1988 fiero 2.5 runs for a few minutes then dies. please help
I have a 88 fiero 2.5. It will fire right up when cold and run a few minutes then die. After it dies it will spray fuel when you turn the key on and it will start but will nor continue to spray and only runs a second then dues. If it sits about 20 minutes it will start and run for 10 minutes or so they die and not spray fuel. I have replace the crankshaft sensor and ignition module and coolant temp sensor and nothing has changed it.

Sounds like a bad ECU. I had exactly the same problem on an '88 with a 2.5.
Over time, the conformal coating on the main circuit board shrinks, and bends the board, breaking it in random places. The solution is to buy a new or remanufactured ECU.
