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 the coolant temp sensor, the wire that connects to it is a little corroded and i think it might be bad itself.....someone please give me some answers so i drive my car

 

does the motor turn over but just not start? do you have a map sensor or maf.?? try checking the grounds for the injectors and maybe even replace the fuses for injectors for hell of it. when it doesnt start, can you hear the fuel pump prime with key set to on position? when they installed the distributor did they time it to specs. how old are the spark plugs? does when you turn the motor over does it act like it wants to start or does sound like its out of gas. Is the whole distributor and it components inside new?
