: '03 Escalade intermittently won't start!

Hi,

I have an '03 Escalade that intermittently won't start. It just started doing this in the last week. I was at the gas station and shut off the vehicle to fill up and when I got back in and tried to start it up it wouldn't crank. All lights and chimes were going, just no crank. I tried everything I could think of and then quit trying and spent approx. 30 minutes reading through the manual... after which I tried again and it started right up.

It has done this to me three times now and I am afraid to drive it anywhere.

I have read through other posts and have tried everything I could find. I checked the fuel pump fuses and they were all okay, I ordered a new ignition switch and installed it this evening, however the vehicle still won't start. I'm guessing if I let it sit for a couple hours it will start right up though.

Is there possibly a faulty security sensor or something? I used to drive an Alero for work and it had a faulty security system that twice did pretty much the same thing. It just wouldn't start for 30 minutes after it tripped. Anyone heard of anything like this on an Escalade? Any help is appreciated!

this happened to a friend of mine and it was his starter wires,but he did have to replace the starter

have you checked battery voltage by chance? My girlfriend was having similar issues with her 03, I put my volt meter on it and it read 10.5. Needless to say I changed it out last week and no more issue. With the truck off batt voltage should be in the area of 12.2-12.5 with the vehicle on in the area of 14.0-14.5.

It could be a cell starting to go in the battery, as said above have it checked. :)

Check for corrosion or loose battery terminals.

What does it do when it does not crank? You said all the lights, etc still work..

Does it click once? Click at all? Click repeatedly? I would check to make sure your battery cables are tight and corrosion free as suggested earlier, but other than that I would doubt it is a battery issue.. I believe the security setup on these trucks will cut the fuel off which will cause allow the vehicle to crank but not start - not what you are experiencing..

Depending on if it clicks or not you may have a starter on its way...

Did you ever solve the problem? I am having the same issue and am curious if you were able to fix your issue?

Don't forget the fuel pump... this happened to my son in laws 1999 Tahoe... quits or will not start. Let it sit for a couple of hours and it starts just fine until everything warms up... dealer replaced the fuel pump... solved the problem.:yup:

Thanks -- the Dealer checked the pump and said it was fine. I read on some other posts that the crank sensor can go bad -- I am going to have that checked tomorrow so hopefully that is the problem. Or else I guess there are just gremlins in the electrical system :)

Did you ever figure out what the problem was? Our 03 is doing the same exact thing!! Happened twice within two weeks.

Thanks

The Alero was pretty notorious for Passlock 2 problems, just like the 1st generation malibu. Check for the security message to appear in the info window when cranking. If its there ur stuck! If not problem may be elsewhere. I doubt the crank sensor tho, as this is vital for the engine to run, if would show other issues while the engine is running and not only upon startup. Would be interesting to know if there is a click at the starter, or nothing at all?

I don't think there is a click - just nothing. It starts now so I can't check for sure!! We found this on another site:

'We have yet to ID something that causes the passlock system to think it is being stolen, and cuts off the fuel flow. The only work-around that seems to work every time is to wait one full hour and then try, and it always starts. But waiting one hour is not very practical 99% of the time. I read someplace that when it malfunctions, you turn the key to the "on" position, and wait a few minutes, till the "security" light on the dash goes out, then it should start. But, wouldn't you know it, I can't get it to malfunction, so I can't test that work-around. Anyone have any ideas? Thanks.

This is true. Turn the key to the start position & wait 10 minutes. If you don't have kids making noise anyway, turn the radio off & listen. You can actually hear the thing unlock.

Anyone out there know what to cut to by pass the PassLock system completely??? I guess this is a common issue.'

So, I guess next time this happens we are going to try this.

Thanks.

The waiting period of 10 minutes with the key on is the reprogram feature. When replacing the ignition barrel, the resistance doesn't match the known value of the PCM, so the passlock is activated. Leave the key on for 10 or so minutes, till the security or theft light stops blinking and stays lit, key off. Wait a few seconds then on and system should be functionnal. This learn routine will not work on a defect passlock, where the resistance is sometimes not seen by the PCM.

I bypassed the passlock on my truck. Its the most reliable way of installing a remote start (no bypass relay needed), its a pretty non-effective theft system anyways, and I got a good aftermarket alarm. Add to that the fact that it sumtimes fail when not convenient, so it was an easy choice to make. Very easy to do I can post instructions how to do it if you have a good digital probe and got soldering wires experience.

Look for the theft or security light next time it happens. Keep us posted.

Hey- thanks!!

You probably won't hear from me in a while since its working fine now. Last time it took 2 weeks to do it again. Anxious to see if thats the fix. Better than another $2,000 repair bill. Last month it was the differential, oh and the A/C compressor! It does have almost 180,000 miles on it though.

Milage might also be an extra hint pointing to the passlock (key cylinder wearing out). Cost to bypass the system about $2 for the variable resistor. Let me know.

SK7 - I am interested in the bypass details for the "passlock" system. My daughter's '00 is experiencing starting issues with a remote start install. We've replaced many parts (dealership) and still it acts up! Help!

No prob! I'll post instructions how to with pics in a different thread. Tomorrow 4 sure, my brain is still in limp mode after a few nite shifts...

Probably NOT the security system. I had a problem with the security system when I first got the truck. The truck WILL crank, but not start.
The initial post says it does NOT crank. I think he would have noticed a flashing yellow or solid yellow caution in the instrument panel.
Check for codes????

Thanks sk7!!! I'll look for your new thread!

Oldword is correct, the passlock doesn't cutoff the starter. But if you are experiencing remote start issues, then permanent bypass of the PK2 is the way to go!

Just happened to me with the exact same symptoms. I had my mechanics rebuild the starter and everything works great now.

Dear sir,
I have an 03 escalade. It will only start after waiting 10 min or so. The batt is fine. It was at inspection station when they turned it off after doing thier OBD diag. Car passed then wouldnt start so they can move it out of line. Can u explain this reprogram passlock fix that worked for you? I cant afford to take to dealer. Im no mechanic so explain it as if your telling a 10 year old. Thanks

Haha. I know it's not funny but this problem occurred to me 5 times already today. The first time it happened was last month. I have an 06 esv. Battery in perfect shape. All lights and electrical accessories inside and outside the truck works fine when this happens. I put in the key and turn it to start. Nothing happens. No crank. No sound. Lights on dashboard, stereo fades just like when I start normally but without sound or action. I sit there a couple of minutes to wait then do it again. Nothing. Wait couple more minutes then I get it to start normally.
I do all sorts of weird ritual every time this happens like closing, opening doors; Putting gear on drive; Release parking brake as I switch the ignition hoping this would start the engine. But nothing happens. I just repeat the process of waiting and guessing and starting.

Now here's the best part. I went to get my car washed today. Shut off the engine and for my vacuuming done. Truck started normally with my fingers crossed to move to the washing bay area. Shut it off. Washing finished so I was told to move to air drying and wiping area. Truck wont start. Sweat running down my forehead as other trucks behind me were waiting. One worker came and helped me. He tried but truck still won't start. The he did some trick. Blew my mind away. He kind of pushed the key in in the ignition and wiggled it. VIOLA. Started the truck! And he said: "I've seen this problem many times before with all those big GM trucks. Same thing happened and same pushing in and wiggling of the key solves the problem". I LMFAO.

So what seems to be causing this starter problem? Why would pushing the key hole in and wiggling of the key solve the issue? At least for me. Coz it's not normal for an escalade to behave like that.

I think the key switch is getting worn and causing a intermittent connection at times

Ok...today is a first. I walk out to parking lot from work and nothing! I get chimes, int lights, windows work, dash lights on, batt gauge moves to 12.0 but turn ignition i get silence. I wiggled the key, pushed it in and still nothing! Today is especially hot. Could this effect the starter?

1.) Starts in morning...if driven long cart wont start again for ten minutes.
2.) Key does appear to be aftermarket key...but this wasnt a issue when i bought the SUV months ago.
3.) One of the Dash icons is the car with the padlock over it. This lights up when turning the ig...but so do others.
4.) Today first time it wont start at all when it hasnt been driven.
5.) My mechanic is suspecting the starter.
But the starter being or getting hot will stop a vehicle from starting?

Most likely the starter solenoid has failed but to be sure it ain't the padlock system is the lock going off after the truck is started or does it stay on?
If no then its the starter or relay(if it clicks loud its good) I had the starter fail on me(luckily I was at my uncles house and he drove me home back home till I could get it towed to the shop to have the starter replaced

Age may have a hand in its failure as heat rarely keeps them from working its either it does or it doesn't

FWIW, my 05 had that problem, left me stranded once about 60 miles from home.

In my case I had some kind of short in the starter itself, the solenoid maybe? Not only would it not start at times but it would also drain the battery sometimes in only about 8-10 hours. The starter body never got hot so it wasn't a major short, but enough to kill it overnight.

I put in a new starter after killing a new battery thinking that was the problem and I never had the issue repeat itself. I've changed out a dozen or so starters in my lifetime but never experienced this type of failure before my Escalade. Usually the starter either works or doesn't, or you have to tap the solenoid on the side of the starter to get it to engage. This was a new one for me.

got the same problem with my 03 cts, did u figure it out yet?

My 00 STS began showing the same symptoms many shared here with good lights/gauges, etc, but no start or sounds when ignition turned to start. I tried the WD-40 trick to no avail and bought a dealer key with no fix. I have figured out that it will start every time after the key has been in the ignition on "run" for 2 minutes. (the security light only stays on for a few seconds, not the entire 2 minutes) Anyone else tried the 2 minute mark? My next step appears to be either the ignition cylinder lock or the pcm since it starts every time after 2 minutes.

I don't know if this is a coincidence, but I changed the battery in the keyless entry FOB and my STS has started immediately, every time, for the last 3 days.

OK, the car seems to start fine when it is 80 degrees or more outside. Tried changing the battery and the starter, as well as cleaning battery ground under the seat and ground under the hood; no fix yet. Also bought a new relay for Start 1.

I'm having the same problem... When I crank it over nothing happens, all the dash lights turn on, then extinguish as they've done before. I replaced the starter in 09 and
pulled it for a bench test & it passed. I just purchased an ignition starter switch Duralast PT#LS1115 but I don't know where or how to install it. Can't find any write ups but read somewhere it's on the column. If so how do you remove the column cover & or steering wheel to change it out? By the way after I reinstalled the starter the truck
fired right up geez.. Any help would be greatly appreciated.

Could you hit me up with that info as well. I am in the middle of trouble shooting mine as well. Turn the key and dash lights up, but no sound at all from the solenoid. Was figuring a bad starter/solenoid. My battery is also sometimes having draining issues. Mines is a 2004 ESV
