i have an '88 iroc-z 350 tpi and when i try to start the engine when it is cold it is fine, but if it is even the slightest bit heated up it will not start, any suggestions? please help

 

3rd gen starters are **** to what we call "heat sink" it is caused by the starter being positioned so close to the exhaust and after a short time of driving the solanoid will heat up and when you try to start it next time it will not start or start hard

it happen to me when i had my first 3rd gen a 1986 z28 b4c police pkg i had to replace the whole starter but after i should have just replaced the solanoid

first i would take out your starter and have some one test it to see if it is working properly then you will find out that you will either need a whole new starter or it is just the solanoid and i would also install a heat shield or wrap it with some of that heat tape

hope that helped and good luck

 

My car will sorta do that. In the morning I just barely turn my key and the car starts right up. I then drive it to college and a few hours later I leave to go to work and it usually takes 4,5 cranks to fire it up. I have a heat shield on my starter silenoid to protect it since the last one left me in the middle of no where.

 

ya it was the heat shield thanks a lot, now on to other problems
