Question about 1992 Pontiac Grand Prix
My car cranks but doesn't start i changed the starter and fuel filter, it now cranks and acts like its going to start but dies after a second or two. I checked the fuel pressure and there is no pressure at all. But at times there seems to be good pressure but now its as if it has lost all pressure, fuel pump works. What should I do to fix this problem?
Did you check the fuel pressure at the fuel rail? with key in the on position to activate the pump? If you did and there was no pressure I would first check for the obvious, gas in the tank, leaking fuel from a line, check for flow before the fuel filter, located at the rear of the vehicle near the gas tank. take the fuel pressure line off put it in a catch can and have somebody turn the key to the on position to activate the pump, if it flows chances are the filter is plugged. Also pay attention to the sound of the pump if it is very loud there is a good chance the pump is failing and needs to be replaced. It could also explain why sometimes it dies. The pump is going out of range. Hope this helps

If fuel pump was working you would have fuel pressure.check the relay for the pump, check for power at the pump.
