If you are sure the fuel pump relay is working, check continuity from the pump to the relay socket. These wires love to corrode. When you turn your ignition on, the fuel pump will only run for a couple seconds before it shuts off via the automatic shutdown relay. Make sure you are checking power within this window. The PCM (powertrain control module) is what completes the ground in order for the relay to send power to the pump. If the PCM does not recieve a signal from several sensors (mainly the Crank Sensor) it will not turn on the pump. You may want to check these sensors, is the check engine light on? You can scan it to see if any sensors have thrown a code. Be sure all applicable fuses are ok, the PCM may have its own fuse, check that even if the fuel pump fuse is ok. Your Truck may also have an inertia switch for the fuel pump which shuts it off during an accident. Check that as well.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

SOURCE: process to change fuel pump on 2001 chevy silverado 1500

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.

I have a 1996 chevy silverado 2500 every once in a while it will stop running,when i pull the fuel pump relay out and put back in it starts back up. it is very warm to the touch,just noticed today tha


I would just replace the relay. Then if it still happens, your fuel pump is drawing too many amps. Causing the relay to overheat and shut off. Time to replace the pump, before it dies on you.

96 chevy truck, fuel pump relay switch (located under the hood, driver's side wheel well) keeps shorting out and melting fuse panel


I would replace the fuel pump and the fuel pump connector, both have problems in this year that cause excessive current draw and blow the fuse and overheat the system. If the relay socket terminals are discolored from heat that must be replaced as well. Of course before replacing any parts have a GM dealer confirm the problems i have guessed are to the cause.

Chevy Silverado 2002 2500 shows trouble code, P0230, and P0300


P0230 - Fuel Pump Primary Circuit Malfunction Symptoms - Engine Light ON (or Service Engine Soon Warning Light) Possible causes - Blown Fuel Pump fuse
- Open Fuel Pump Monitor Circuit
- Faulty Fuel Pump Relay
- Damaged ECM. P0230 Description The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. When the ignition switch is first turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump. The ECM enables the fuel pump relay as long as the engine is cranking or running, and crankshaft reference pulses are received. If no crankshaft reference pulses are received, the ECM de-energizes the fuel pump relay after 2 seconds. The ECM monitors the voltage on the fuel pump relay control circuit.
Please go to this LINK for P0300 diagnosis.
