Be sure you have checked the impact safety switch. Your owner's manuual should tell you where it is if it has one. This switch kills the power to the fuel pump after impact. It has a push button reset. Check for voltage at fuel pump to rule out having to change the pump again.

Your pump is controlled by the pcm using a 12 volt signal to the relay. Pull out the relay and probe the relay socket with a voltmeter. There should be 2 terminals with 12 volts when the key is on. With the key off, there should be one 12 volt terminal coming from the ecm b fuse. See top left of diagram below.

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.

1997 Chevy Suburban Changed fuel pump fuel filter relay new battery engine turns over but will not start. Getting spark. Took off fuel lines going in top of engine not pumping fuel. Any suggestions


There is a fuse that deals with the fuel pump circuit through the ECM. If you haven't checked it's in the fuse panel under the hood in the engine compartment on the drivers side by the brake master cylinder. I hope that you have a cover for it with the names of the fuses. The fuse you want to check will be the fuse marked "ECM B". I gave you a picture of the fuse layout but it's not a good one but I did put an arrow to the one I think it is. I pretty sure that's the one but not 100 percent because it's pretty blurry. In any case there is a fuse marked "ECM B". I would check there if you haven't already. Other than that You may have to check your wiring. There is a fuseable link at the starter you may want to check if that fuse isn't blown. I hope this helps and good luck.

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

Where is the fuel pump relay fuse on a 1991 camaro with 305 engine?


I do believe it is located in the "relays" panel under the hood. Look on top/cover for "Fuel Pump".
Most likey a 10a fuse.

Not getting fuel to carberator i changed the pump filter and relay


Other things to check, do the dome lights work? If not change the fuse for those and try again. When its quiet around you turn the key all the way on but don't crank the engine. You should hear the pump kick on. But if the fuse is blown for the Dome lights and the Radio it also kills the ECM which kills the fuel pump since the ECM turns on the fuel pump. And the 91 does not use a carb, its a Throttle body injection system.
