Fuel pump warning light came on and the fuel gauge did not register. After a few minutes the lamp went out and the gauge starting working again. Any ideas

you used voltmeter at the pump?> or just didnt here it run
do say this...please. details, matter....
it told you low fuel is it? is the fuel gauge near "E"
why not state that first.?
dead gauges, be 1st right, smacks of gross power loss.
right>? not clear to me what no gauges means.
but the voltmeter is #1 no?

did you tests fuse that look ok. fuse that look ok can be bad.
no gauges, means all dead, no movement,
well the fuel gauge must work , does it, does it match reality?
cranks but never runs. good input there.

does not run for the jeep 3 seconds.? (ASD rules)
no 12vdc power to pump, when cranking,?

is the skim lamp off, the cluster lamp for SKIM security is first.
it must go out after key turn on, or it will never run, ever.
I can help.

this jeep has a voltage gauge, it must read 12v keyon
if not power is lost, or battery low.
if cranks that tells me the fues blew.
skim cuts spark and fuel, not cranking btw.

see that lamp 12, if stuck on car will never start but will crank.
the lamp falses if skim is not working or stays on for ******* key.
we SCAN ALL CARS NOW.
IF You can not scan a modern jeep then it can near impossible to diagnose (a hard cold fact)
IF the ASD fails to work, the PCM tells you every time
all 8 ways for it to fail.
but that takes a scan tool (any modern scanner works,)

The engine temperature is normal?
If any warning lights have appeared on your dashboard, this may point towards a faulty sensor such as throttle position sensor, Oxygen sensor ..

If you have no warning lights it sounds like a classic case of a faulty/failing fuel pump.


Nissan Sentra Fuel Pumps

The pump fits into the fuel tank.
A quick check you can do is to disconnect the fuel line somewhere in the engine bay and turn the ignition on. Fuel should literally spray out.

Before buying and fitting a new fuel pump get somebody - a workshop - to do a pressure check on it/ confirm that it is the fuel pump.

A faulty/failing fuel pump can work intermittently. One minute it's fine, the next minute it stops working.

depending on your year, make and model. most are located in the fuel tank with the electric fuel pump.

Where did you buy the alternator? Charge the battery and have them both tested.

try hold up the key while starting, shot in the dark. if it startes remove extra items off key ring

You probably have a bad fuel relay switch. It is located in the engine compartment in the fuse box. It costs about ten bucks and takes 2 minutes to change. I hate to say it but you probably didn't need a new fuel pump. If the relay is not the problem then it will be your fuel pressure regulator about $60. This part will affect your fuel gauge and cause intermittent starts and stalls or a no start. If your car sits for awhile the pressure will fall off and the car will start again but will not run well and it can stall out at anytime and not re-start.

The LS Lincoln Has 2 Fuel Pumps . The One On The Drivers Side Is Called A Transfer Pump , It Pumps Fuel From Drivers Side Of Tank To Passenger Side Both Pumps Have Sending Units On Them The Transfer Pump Sending Unit Was Bad

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

Hey Mudkicker,

Who ever thought of putting an electric fuel pump inside a tank of gas........

Check your other gauges for accuracy. They do that when a ground is loose.

Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.

Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.

Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes

Comment me back

Check the fuel pump relay:


It is below the park lamp relay.
