Question about Cars & Trucks
How can I tell if the problem is the fuel pump? I've checked all the fuses and they seem to bee good. I've even disconected the battery thin king it may reset the computer and car would start. When I turn key to "on" I don't hear the humming noise of the fuel pump.
This procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.
·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

A mechanic would check fuel pressure, and check the pump relay to see if it is powering the pump when the key switch is turned on.
