I have a issue with my 93 z28. I will be driving and it just turns off. Sometimes it starts right back up then sometimes it takes forever. Does anyone know why this keeps happening. I have put a new fuel pump and fuel pump relay. Is there anything else I can do before I go crazy?

 

ignition control module may be failing, also ignition switch failing can do this. I have had both happen in my 93. the module has to cool off before it will let you start again. until I changed to coil per cylinder I carried a extra icm in the car. with the switch I had to get the switch/key in the right place for it to start. once it got so bad it did it while driving and I held the key in a certain position to get me home and then it was toast and would not run until I replaced the switch.

 

I will check that out thanks for everyone's input on this issue
