My car will not start. When I try to start the car it does nothing. No clicking or anything. Initially it had blinking Check Engine Light. This is an indication there is a serious problem. I had AZ test my battery and it is good, and I have a new starter, so the problem is somewhere in the system. So I borrowed a Code Scanner from AutoZone and I am trying to read failure codes. I used the information from the code scanner, I got a code P0346-00, and it was telling me the Cam Sensors may have a problem. Well, the Cam Sensors had cracked connectors from a previous repair. So I replaced the connectors and the sensors, and the failure code went away. I also replaced the MAP (its and intake Air sensor) because the connector was also damaged and was seriously corroded with oil.
The first three pictures are the initial Failure codes I was working with.
When I try to start the car now, it still does nothing, no clicking, just nothing. The blinking Check Engine light is gone. But the ignition won't allow me to remove the key. So I have to use a tool to remove the key. I ran a scan tool a second time I will post that information in the next Reply below.

Anyone have any ideas?

i haven't found a pinout yet for that connector.
it doesn't look like a splicepack but i'm not familiar with the ones used in the caddy, i can try and look for it in my car but mine is a 2008 so it likely won't be the same.
when i was at the wreckers i seen what appeared to be the splice pack with 3 strips of green combs

The fact that someone was in there before is interesting. You may be getting warmer.

geocoy2 · Mar 27, 2023

Well I am surprised to see somebody has worked on this before, I still think this issue has something to do with the repairs I made when I replaced the right front Catalytic Converter. I was getting occasional blinking prior to that but it was just incidental blinking of the dash gages. Still, you can't help wondering about the wiring repairs, what were they trying to do?
Almost forgot, what have you discovered about the pins on the connector?

what does it connect to?

A closer look at the taped-up wire.

First of all this is a major connector, judging by the shear size of it I dont know if it is SP200 or not. You picture of the SP 200 places it next to the steering wheel taped to a harness. That description seems to fit where I found it. BUT my Repair manual says SP 200 is under the glove box???

Where does this connector go?

The female side of the connector runs straight toward the engine bay for about 5 inches, then it makes an abrupt turn upwards where it fastens to a large aluminum frame. I cannot see it after that, but I can feel it making a turn and I am thinking it goes straight to the engine bay.

See the pics below for possible places where it comes thru the firewall to the engine bay.

This is a larger view of the engine bay so you can see where the wiring comes thru the firewall.

that is not the spice pack. that appears to be one of two possibly three steering column connectors.

1997_eldorado · Mar 27, 2023

1997_eldorado · Mar 27, 2023

that connector that you pointed out is the steering column connector and i believe there are three connectors total. and i believe they are the ones you've pictured.
regardless of who done them patches i would remove the tape inspect and solder the joints possibly put some heat shrink tubing on them to protect them rather than tape.

weather wasn't nice today so i didn't get to look under my dash.

I can do that

1997_eldorado · Mar 28, 2023

can u take a clear picture of the connector i pointed to?
and if possible take the cover off

Team ZR-1 · Mar 28, 2023

We can just do more guessing, but GM does not take a black (known as for Ground)
and do a bad splice like that to orange ? Which is normally a switched voltage circuit

I wonder if a past owner put in a cut-off switch to prevent theft and added a switch out of sight to prevent startup
Guessing has to stop, must determine what the pinout is for that connector and GM wiring drawing showing
at the least, what circuits those to wires are for

Maybe if they added an ign lockout that switch is outside the car, and you bumped it when doing the CAT work
but clearly once seeing what the 2 GM wires are for would then answer why the splice was done and how to undo that splice and any others
GM would have used heat shrink and so far see non GM blue and black tap
Determine the black wire going to that 6 pin connector where that plugs into and what each of the 6 wires purpose is

Is that all black or also with a white stripe, and is the other color solid orange ?

You need to follow the wiring connectors pin outs 1997_eldorado
has been supplying and find as with this large connector, which one as example has a blue wire at the end and looks like an orange in next position would then tell you for sure what circuits are in that connector

Also, if in fact the connector by its colors is the splice pack you're looking for \?

Team ZR-1 · Mar 28, 2023

Also, have not answered to the other photo I posted if that is another splice job that is blue to the left by firewall ?

1997_eldorado · Mar 28, 2023

as Team ZR1 said they need to be traced to determine what their purpose is.
where does that white connector go so i can see if i can find a diagram

1997_eldorado · Mar 28, 2023

a clear pic of that 6 pin white connector as well
i haven't been able to locate that one thus far
what is it connected to?

geocoy2 · Mar 29, 2023

Also Team ZR1

I plan to trace the wiring to see where it leads
You gave me the pin info for this white connector, it plugs into the ignition switch
I plan to open up those wires that are taped together and make sure they have good connections. May have to acquire a soldering gun, I did not do a good job with the torch.

I was just about to say this is the only one we did not find yet and I noticed this pic on post # 260, this looks a lot like the connector we are looking for. Could it be correct?

Team ZR-1 · Mar 29, 2023

He cannot go further until he sees what the pinout is for that white connector,
what each of the wires is for and WHY was that splice done, not just if the splice is good

Report here what each circuit wire is for and exactly what color wires with that splice

GM does do crap splices like that, looks like painter tape used

Right now, I'm feeling a little stupid that I never noticed this connector / switch is not on any of the pictures of the ignition switch in my manual. This has to be something someone added, but who and why?

1997_eldorado · Mar 30, 2023

that is not something added.......unless it was also added to the car that was in the wreckers i went to.

appears to be

Team ZR-1 · Mar 30, 2023

Does not match as that is a 6 pin connector which looks like 4 wires inserted
and post #188 wire colors do not match and has 6 wires
where is the VATS circuit to that connector ?

1997_eldorado · Mar 30, 2023

yup i see that now......6 pins in one row

1997_eldorado · Mar 31, 2023

i do recall the old 97 eldorado had an aftermarket remote start hooked up and also a bypass that was needed for it..... which once removed left a couple of unused connectors. the wiring mess they left was not pretty but luckily no issues

geocoy2 · Apr 1, 2023

Plan to get back at this today, having a few health issues because of the weather

1997_eldorado · Apr 1, 2023

as always take care of yourself first.
hope ya feel better soon

This is the pin count you sent me a while back for the white connector that has the taped-up wires. I'll see what I can do to repair this taped up wiring.

Team ZR-1 · Apr 2, 2023

You still have not answered what was done under that blue tape ? ? ?

And do the color of wires follow the exact pinouts of that connector ?

geocoy2 · Apr 2, 2023

I working on exactly that sir

Team ZR-1 · Apr 2, 2023

Damn, you stumbled onto a real rat's nest !
Wonder what the 4 fuses block is for, if even stock and looks like only 2 amp fuses ?
Any voltage to that fuse block and all fuses good ?
I doubt GM would have had that fuse block that is hidden and no easy way to replace fuses if need be

Very odd for what looks like multi hand splices, and what the hell were they trying to do ?

Still smells like some security
power cut off for ign to prevent starts ?

A little history. I bought this car in 2005 at a used car lot. I've been suspicious all these years why it was in a used car lot. I noticed it had a GM Union insignia on the door (in the area of the latch) that made me believe it was owned by an employee of GM. I NOTCED the front wheels had serious dents in the front rims, like it was driven very hard. I only had it a few months when the rear wheel bearings, both wheels locked up. It caused damage to the transfer case. It was under warranty so GM replaced them. Then after a few years it started having a check engine lite issue. Dealer told me to replace the gas cap and that fixed the problem for about 5 years.
The whole thing was very strange.

1997_eldorado · Apr 2, 2023

i believe the 2 amp fuses are for the steering wheel controls. and yes i think its a stupid place to put them

never nice to try and figure out the hacks and slashes tho

n7don_srx · Apr 2, 2023

I discovered two blue tape "connections" in the TCM connector on the 2007 SRX. Bought the car new so no aftermarket add-ons. So there's possibility it's something GM did and not aftermarket

1997_eldorado · Apr 2, 2023

i would say that is unusual......but the quality turned out today it doesn't surprise me....cheapest fix is usually all that is required.

the remote start that was installed in the 97 eldo had a hack and slash install done by what one would call a well know large car service center.
every wire used for the install of the remote start and security bypass was black with not so well taped connections, no soldered joints. as i mentioned i was lucky not to have any issues related to that but it wasn't for the quality of the install.
wiring problems are a PITA in an untouched system let alone a spliced one
