please need help still
my 89 305tpi camaro has a problem. when i first start it up( motor is cold) it drives and runs fine. when i shut the car off and go to start it again (motor is warm) it wont start. its at the shop and they tested the wires that cap on to the fuel injectors and when hot the light is very dim compared to very bright when cold. they just put in a new distributor, ignition coil so its not an ignition problem...... starting to think that the problem is in the harness because my car sat and mice made a home inside the dash.....someone please give me some answers so i drive my car

I guess since it is at the shop, have the shop check the resistance of the injectors while hot. The ones that are under 12 ohms are bad. Just replace them all.

Re: please need help still
I got a car in my shop right now with the same problem. At first I thought it was in the tunning or the ignition and if I spray a little gas in the tb it fires right up. I think it might be an injector like Rbob said. I'm going to check it out today. 89tpi you should try that first before spending money on parts. imo
