I have a 89 camaro I personally don't think it's a fuel pump issue and I recently changed the relay, but whenever I turn the key over sometimes I hear the fuel pump turn on sometimes I don't. Could it be a bad sensor or possible the fuel pump if I'm wrong?
Added from comments/answers:
Update 1: The car stalls while driving but usually cranks right back up but now it doesn't at all
Update 2: If the fuel pump not giving enough pressure do I have to replace it?
Update 3: Yes it's OBD1 it's just been sitting there for so long and I've been trying to solve the problem myself, I'm just gonna take it to a mechanic.
