[quote=”wysetech” post=111784]Yeah…..G.M. had issues with older cars as well. The switch smoked sometimes so they recalled them and installed a relay for the starter solenoid on the radiator support.[/quote]

I have read about that issue you described…I also want to thanks you for the input on the fuel pressure rising in the tank, and that is probably why I got the strange fuel pressure issue

[quote=”wysetech” post=111781]I didn’t read carefully through all of the help replies (seems like I missed or ignored this post) but did anyone ever consider that it might be the infamous G.M. ignition switch issue?

I don’t know of any vehicle that will hold fuel pressure forever after shut down. The heat of the day could make the fuel pressure rise by itself also.

Just some random thoughts :unsure:[/quote]
thanks you for your input, I appreciate it… GOOD CALL!

The Cavalier is an 04, and there was no recall for the ignition switch, however the owner mentioned to me that it maybe an ignition switch issue, because of the GM ignition switch problems.

I know that I was going to test that switch at some point, but to me it seemed like the ICM was just shutting the engine off…we’ll know at some point what the techs find

[quote=”Tedybear315″ post=111708]There is no shame in having to see the project go to a dealership. They have some special tools and test thingies that hopefully will allow the issue to be found.

Please keep us informed as to what the final resolution is. Most of us have our PopCorn at the ready and have been following this with great interest.

Don’t feel bad at all!! This has stumped the bulk of us as well.

Plus everything you have done? Was NEEDED repair, and not throwing unwarranted parts.

Sometimes you just gotta keep the faith!

(That’s my RAH RAH speech. Any good?)

Just kidding. Actually we’ve all been there at some point in time. I’ve had issues stump the batcrap out of me on some of the complex games I work on. And it pains me to say “I can’t do this, Can we send it back to the field support center and have the bench techs look it over?”

So while it might hurt the pride? It’s the right call.

Just let us know what they find out!!

Thanks for the ” RAH RAH ” speach, and yes it was good:) and made me feel better already 🙂
So, for now it’s back to building my boat engine, which I have neglected to work on over the weeks…it’s calling my name Lol..

With the cavalier, watch it turn out to be the battery…I have a load tester but didn’t think about using it…
When I know what the tech think the problem is, I’ll post it so we’ll all know and could help others in this form

Thanks again Tedybear315

for all who have been interested in this thread, I thought y’all would like to know where I’m at with the issue.

The owner, who is a vary close friend decided to come pick up the car and take it to a Chevrolet dealership to have it a professional tech try and pinpoint what is causing the issue. I thought it was a good idea at this point since I’m not a professional tech, just a ” Shade Tree Tech “. I hope that whoever works on it, graduated from ScannerDanners class with top honors!!

I feel like I have failed, because I had the car for a few weeks, and could only work on it a limited time after work, and weekends. I ran some test, and replaced a leaking fpr, and installed a new fuel filter, but couldn’t pinpoint what was causing the stalling, because of limited time. I felt like I was in the right track with it being an electrical issue, but it would have taken me a bit longer, and more troubleshooting procedures on the CSI system.

My friend is in no way upset at me or nothing,he and his wife are cool folks, but they need to know what exactly is causing the issue, instead of throwing parts at it…and I agree

I will post what is going on, or what the tech thinks is going on with the enging, ASAP.

I would like to know too, and are awaiting for the diagnosis

[quote=”EricTheCarGuy” post=111686]Based on what you’ve posted there I would say that fuel pressure is not the issue. I believe it’s time to turn your attention to the ignition system. Have you replaced any parts there recently? I also noticed a bunch of wires that looked like they would belong in a harness on the back side of the engine. Have these wires been tampered with in some way?[/quote]

Thanks for the input Eric…I too think it’s an electrical issue.
This car was purchase at a used car lot, and yes someone was into most of the wiring at some point. I have noticed old electrical tape over wires, also some new wire looms,skinned wires for probing, which was all covered up.

I have done major work to this car in the past, but never bothered the wiring harness, except for unplugging electrical connectors. This issue just popped up a few months after I completed the work, and after sever thousand miles were put on the engine.

I don’t have the car here at my home to work on at the moment, and will explain where it is in a separate post

thanks again

I second teadybear315 comment….I can only remember using rtv sealant when doing a intake or oil pan gasket, and in on specific locations per manual
