Car dies and shuts down

[doug41686]

I have a 97 gsx, I had a high performance fuel pump get put in,all new belts including timing. I thought the problem was the high performance pump so i put the stock pump back in. When my car is just running it will just shut down. It could be 5 min or it could be 30min. I have no idea what is causing this please helppp!!!!

Are you getting any check engine lights? before it shuts down?

 

[doug41686]

no check engine lights come on

not all problems will trigger a idiot light. My advice have it checked to see if there are codes on there.

the code that states on the car is misfire but i'm getting spark and the fuel pump is good. i think the pump might be shutting down for some reason?

Check or replace the crankshaft position sensor and camshaft position sensor.
Let me know if it works.
