Question about 2002 Chevrolet Silverado 1500
Fuel pumps up then turns over but wont crank
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.

SOURCE: FUEL PUMP FOR CHEVY SILVERADO
fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?

First check the fuel pump fuse in the fuse panel to make sure its not blown. Chances are that it is the fuel pump, that is a common problem with chevy trucks. The easiest way to access the fuel pump is to remove the bed of the truck from the frame. Good luck. dont forget to rate.

Should be on the passenger side kickplate below the glovebox and to the right. You may have to remove the plastic panel to access it or look for a small hole in it and feel around for the button

take the six bed bolt loose and then take three buddies slide the bed back put in the new pump slide it back n place and put the bed bolts back in. if u drop the tank u can easily break the hard plastis lines that go to the fuel tank. u only have to take the fill lines and taillight wires loose this way its alot quicker, and easier.

The best way to help find the problem, is to have a fuel pressure test done on it, that will tell if the fuel pump is weak, or the fuel pressure regulator is malfunctioning. If the pressure is low, the fuel pump is weak,
if it is high, the fuel regulator is at fault.
