: Help my 94 fleetwood won't start !! Passkey fault light steady on

My 94 fleetwood won't start, the passkey fault light is steady on when i try to crank it and even when it goes off the car won't start , the light just comes back on. I know it's not the ignition because I bypassed it with a resistor( resistor is 11.82 ohms as it is a number 15 key, i double checked so im 100 % sure it's correct) So what could the problem be ? Could the starter being faulty cause the passkey light to come on? any help would be greatly appreciated as I don't know where to go from here and don't have the money for the dealership. Also I checked the obd and no codes came up only history 01-128, 01-142,01-143,01-144. Im the second owner and car has only 61000 miles,
please help :(

A bad starter won't cause the passkey fault light to come on. Only a passkey fault causes the passkey light to come on. It sounds like you might have something fishy with your bypass. Or did you install the bypass to try to correct the no-crank condition? If you leave the key turned on for 3 minutes and then crank it, it will start if it's a passkey fault.

My '94 has been sketchy starting lately. Sometimes it won't crank. If I work the ignition (turn it to start and back several times) it will eventually go. It's random. I think it's the solenoid (part of the starter). When it fails completely I'll replace it.

Some cars with passkey problems will start if you leave the key in the on position for about 15 minutes. I know you dont think its related to the passkey but, if it hasnt started since the security light came on...

Yeah i though it might had been the ignition so i cut the wire under the dash to check the reading, and it was good, but decided to bypass it anyways to avoid problems down the road. So what you are telling me is that its not a passkey fault cause the car won't crank at all even when the light goes off after 3 minutes, so its possibly a problem with the starter or its solenoid? Do you know of a way to check that?

That's news to me , leaving the key in ON position for 15 mins and then cause all pass key fault problems ?
Wish I could help the OP , but I do have an idea and hopefully works for him , unplug the negative battery cable for 15 mins and re attach it ? May be this 15 min trick works for you

I'm going on memory, but I believe the Passkey timeout is 180 seconds (3 minutes). If it's a Passkey issue, it should crank after 3 minutes.

It could be a starter or solenoid problem. You'd have to check to make sure you're getting voltage at the solenoid when it cranks, which means you have to get under the car while someone turns the key. It's the smaller lug on the starter. There might be an easier way, but that's all I can recall at the moment.

theft deterrent module. at the worst. well I had this problem with my 94 roadmaster and my lil brother 94 caddi. hth just my personal experience

I find it to be the owner deterrent module more often. My friend has a 96 and it gave him plenty of problems too.....

+1. Usually a broken wire inside the ignition lock cylinder will cause no crank and Wait for 3 minutes message. If the OP already bypassed the key resistor and it worked for a while, the only other possibility that comes to mind is the module itself. A bad starter would not set that light.

yeah the thing is the car would run just fine with the light on and off for the past couple of months, and last tuesday got up to go to work and it just wouldnt crank anymore,and it never started since, is that a telltale sign of the actual module beeing defective or could that just be a relay or even just a bad ground somewhere? I really don't have any experience whatsoever with those damn VATS but from what i've been reading they are very troublesome

My VATs experience was limited to the broken wire and bypass as a solution. Someone with a bad module experience probably will chime in soon.
Meanwhile check this link (http://caddyinfo.ipbhost.com/index.php?showtopic=42024).

..... really though?Yes, it is a pain when you get stuck and can't start your car. That whole system is too fragile. Wires break, the chip falls out of the key and a host of other problems. If I had that system I would just wire in the resistor value from a pack of resistors from radio shack and be done with it. He eventually had that done. :p Works great now.

I finally decided to tow my car to the dealership today:ill: Ill update later this week to let yall know what the problem was,hope this wont be too expensive

by the way was this very expensive to fix ?

I do not know whether you checked out the link I have found for you, but it looks the dealer will just replace the ignition switch. That is something you could do yourself.

And it would be a waste of time and money if you've already correctly bypassed the VATS.

the problem isnt the ignition,as I have already bypassed it and as it turns out the problem is the module itself, i gotta replace it but GM has discontinued that part, so i gotta find a used one now and have it interrogated to find out the new key number so I can replace the resistor(dont want to pay 100$ for a new key) What a STUPID system!! Wish I could just program the VATS out of the system but I don't know of any shop who do that in my area.:hmm:

You'll need a CCM, then. When you replace it you need to find out what key resistor value it is looking for. The CCM tells the PCM to ground the starter solenoid and turn on the fuel injectors when it sees the right key.

EDIT: That's basically what you said above. I don't know how you 'interrogate' them, but since there's only 15 combinations to try you may be better off trying them yourself.

I had this problem on a past Fleetwood I owned and it was because I worked in a pizzeria and I got flour build up on my key around the chip after I cleaned it and put the key in and out of the ignition a few times while recleaning the key it worked
