I have had this problem with my 87 camaro for a while and it is a total nightmare!!! I can start the car it will run perfect and drive great. I park it turn it off and can't restart it for about 20 minutes. The guy I bought it off of butchered the wiring in the engine. I want to buy a new engine wiring harness and set the wiring back to stock so it might solve my problem but even if It doesn't it would give me a guide of what has been tampered with. I emailed hawks third gen and they don't have any in stock. My camaro is a 305 auto with 74k miles. Does anyone have any I could buy or know of a place or site that sells them. Please and thank you!

 

I will have my 86 engine wiring harness up for sale at the end of next month if you would like.

 

never heard back from u on my harness i have....lmk ty
