Ok I've had this car for a while, it was recently overheating so I replaced the head gasket (but the problem was still there before). I don't know if these problems are In any way related.

1st Problem:
Car won't start due to fuel pump not turning on. This only happens in two situations, if the engine is warm and i try to start it. Then if I park in the sun on a hot day (or if it's just hot) it won't start either.

Things I've tried:
Checked fuel pump - Good,
Swaped Main Fuel Relay (has about 184k on) - Good (maybe, the car runs when cold at least)

Thanks.

 

if your car is still overheating, it could be the thermostat. And for the not starting thing, it could be the fuel pump, main fuel relay, or the ignition fuse, or a bad ground from the chasis to the tranny. Another member just found out what caused his car not to start and it was the fuse.

 

The car doesn't overheat, it runs excellent when once it starts. The problem is getting it started when it is hot outside. I sanded a ground that was from the main relay, hopefully it was the problem. I'll see tomarrow...
