Vehicles have a safty device that kills the fuel pump in case of a roll-over accident so the fuel will not be poured on to the car and ignite. also, this fuel pump kill switch is used when you are going to remove the fuel pump to de-pressurize the fuel line by cranking the engine while the fuel pump safety switch is off. you can restore the power back to the fuel pump by resetting the fuel pump safety (kill) switch. some are located in the trunk, by the fender well, behind the carpet. some are located inside the kick panel where the front passenger sits. check your motor manuel for that vehicle or ask a parts person at the dealership for the location of the safety switch for the fuel pump.

Code p1237 on a 2002 mercury cougar


Code 1237 is for a problem with the fuel pump circuit.
There is a fuel pump driver module in the back of the car that handles voltage going to the pump.
The problem could be the computer, the module, the wiring to the pump, or the pump itself. Each component would need to be checked.

No voltage to electric fuel pump relay?


voltage comes from fuse box, should have a fuel pump fuse, check for blown fuse, if not try jumping a fused wire from 12 volts to relay and see if fuel pump runs, hope this helps ?

My 2002 Intrigue will not start and seems it is starving for fuel.


You said you checked the pump. Is the pump getting voltage after the 3 or 4 seconds from the relay ?
You get voltage for the pump in the first 3 seconds then none if the engine does not start and produce oil pressure. That is to prevent a fire in a wreck.
Can you jumper the pump relay and hear the pump run past 3 seconds ?

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.

My 2002 envoy won't start, turns over fine. I have no power to the fuel pump, I have power at the fuse and relay. Has anyone heard of a camshaft or crankshaft sensor being faulty and turning off power...


You say you have power at the relay, but what part of the relay? If you don't have 12V at the gray wire going to the pump, then maybe the relay is bad. Also check to see what voltage you have on the dark green/white wire, this controls the relay (should be 12V).

No power going to the fuel pump?


the crank sensor is most likely the problem. If the PCM does not sense the engine is cranking then the fuel pump will not turn on. Also just because a fuel pump will run does not mean it will pump fuel.. Jump it while its in the fuel tank to see if it will pump. But still when you turn the key on you only have power to the fuel pump for 3 seconds unless you continue to crank. . If you have a 3 second voltage pulse when you cycle the key on, then spray some quick start or brake cleaner. If it now starts and you know the fuel pump has power then the fuel pump needs replacement. If you don't have the 3 second pulse look at the crank sensor as being the problem,

02 silverado stopped running today while driving..had it towed back to house...think it's the fuel pump...or is there a fuel pump relay that may have gone bad?


Could be a relay or fuse, if ok check for voltage down at fuel pump harness over by gas tank ,probe wire's only one will have voltage with key on , then check other wire's should have voltage at one of the other wire's while cranking engine only and should go away when stop cranking, if you do have that voltage replace fuel pump.Good luck.Let us know if you need more help.
