Did you replace the fuel filter when you replaced the pump ?
Is the pump getting power and ground ?
Do you have normal fuel pressure at the injectors ?

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: ran out of gas, car wouldn't crank replaced fuel pump, fuel relay, and in line fuel filter and still won't crank on 2002 chevy avalanche

still won't crank ? how's your battery ? starter ? starter solonoid ? if your engine does'nt crank , its dead ! would'nt you check the battery first ? then move on with checking the starter circuit ? seems like your putting the cart before the horse ! first of all, when you run out of gas, you need to replace the FUEL FILTER, your engine just sucked the dirt, garbage, etc., out of the tank. there's plenty of sediment in the tank, don't know how it gets there, but, you'd be surprized ! talking threw experience !!! I operate heavy equipment, its a cardinal sin to run out of fuel !!! you say you replaced the inline filter, which one, up by the engine or the main filter, under vehicle along frame ? are we talking about the same animal, PLEASE CLARIFY !

SOURCE: 1996 chevy silverado v8 4.3 won't crank. Replaced

Check the voltage coming from the battery and check it again at the coil.I suspect you are not getting the proper voltage going through. Clean all the terminal ends to bare shiny metal and make sure all the connections are tight. If I remember correct your truck still has the HEI setup with the coil in the top of the distributor cap. If all the voltages are good, 12+ volts you should replace the coil. Hope this helps.

Check spark plugs, leads, distributor cap & rotor arm, fuel pump, fuel filter, coil pack(s), relays, replace any items that are suspect IE Fuel filter which has probably not been changed since new even though they should be changed on all vehicles every 18 months, all of this can be done at home & will save you a lot of bucks in mechanic/garage fees,

Hello. My 1997 Chevy Tahoe refuses to start. The problems began with a bad fuel pump. I changed. It worked. The fuel pump died again. I changed it again and it has been working. I parked it for two weeks....


Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.

1996 silverado 5.7 vortec cranks but wont start. fuel pump, gauges, "idiot" lights, blinkers do not work. flashers and all the rest of lights operate. Just replaced coil and this happens


Had the same problem with my '96 Silverado with 350 Vortec. The truck would only crank. It would start if fuel was poured down the throttle body. Could not hear the fuel pump hum. Fuse was good, but could not hear relay click. Relay was good, Did some electrical wiring trouble shooting. Turned out that one of the connectors that clasp onto one of the pins of the fuel pump relay wasn't making a good connection, too loose. I just stuck a peice of wire into the connector and pushed the relay back in. Relay clicked, Truck Started. It's been more than 4 yrs. since I made that McGuyver fix. Still firing.
