SOURCE: 1998 Mercury Grand Marquis Fuel Pump Replacement

you can try just resetting the fuel pump switch located in the car

the switch is originally in the car for in case of an accident, however, if changed, chances are you also have to reset it

in my 98 grand marquis, the switch is on the left side of the trunk

SOURCE: 1991 camaro RS Fuel pump not working- no power to pump

If the oil pressure switch has two wires on it it may be one that shuts down the pump. I'm not positive but I think it completes a ground circuit, not the hot side though (but may run through a relay.) There should be a pump relay under the hood with a group of other relays. I don't have a wiring diagram for your car but you can get a basic diagram in most inexpensive manuals. They wont usually give you locations but at least you can get an idea of how the system works. There usually is a fuse. If the fuse block is not labeled, use a test light and probe the back of every fuse for power with the key on (takes about ten minutes and faster than trying to find info) change any that are blown. The most likely culprit is a relay, so after testing fuses look for it. (usually on drivers fender or on right side near firewall.) Worst case, trace the power lead all the way through the harness 'till you find where power begins.Testing is important here...I could give you much better info if I was there to do it for you. Most important is to stay "on track" till you find the place where power ends. Don't jump all over the place or you will end up doing an incomplete test.

SOURCE: new fuel pump, hear it run,guage works, car won't start

My Isuzu Bighorn 4jx1 engine of yr. 2000 stalled after having had a hard start for a few day. I changed the fuel filter after I suspected that i might have been sold adulterated diesel. I took a sample of the fuel for test and it was found ok. After checking it out with mechanics we have established that sufficient fuel is not reaching the engine and in particular during idling. My mechanic tells me it is fuel strangulation! We wanted to carry out electronic dignosis but we are unable to located the socket. Where could this be? My enginee is uses common rail mechanism. could there be some valve inside somewhere that has mulfunctioned? Could there be a possibility of low pressure with the fuel system and how to I chech out that?

Car wont start

My routine to check non-starting motors: (petrol/gas models)

  • Check immobilizer status
  • Check fuel supply -does it reach the fuel rail when starting. If not OK, check 12v supply to fuel pump when starting. If OK, fuel pump maybe dead.If not present, check fuel pump fuse and relay.
  • If fuel supply is OK, check spark ignition. If not OK, follow the supply circuit backwards to the ECM. Coils and/or ignition amplifier connector should have one 12v supply to it when ignition switch is on.
For Diesels with 'common rails' you can take same approach for fuel. No ignition testing possible. The diesel fuel pump still needs battery power. It will make some sound when IGN is on. If not, check ALL fuses and relays.

I drive a Nissan 1400 bakkie (not a champ) i drives good and then starts jerking and wants to die as soon i i give petrol it sounds like its smothering

hi, personally ..i love that bakkie. Ok you changed points condensor, petrol filter! please check.. When it cuts out 1. if the ignition coil is not hot, if so thats your problem.2. also on the carb... over the needle and seat there is a tiny filter... somtimes gets blocked. 3. also check when it stolls if the fuel pump is not hot or pull the outlet fuel from the pump
and crank the engine... note if fuel comes out sufficiently.

Feul probelem

disconnect the fuel line near the engine (usually at the throttle body assembly) and turn the key to for a buzzing of the pump..if you dont hear it or see liquid shooting out of the fuel line..theres no power to the pump or it may be bad..if it comes on but no looking at the filter under the car by the front of the gas tank.. it may be plugged can also check the pump for operation by powering it up manually at the pumps connector near the gas tank..if it works there..there is an auto shutoff relay that controlls the pump and the ignition.. it may be bad also..

I have no ignition lights on cluster when ignition is powered on, also fuel pump wont kick on the windows, trunk, wont open. the radio will still work and has light on it and engine will crank just no...

Man ,
This sounds like an alarm or security issue.
if it were a ford I'd say check the fuel shutoff (roll over sensor)...
Maybe a fuesable link?
Check around the posative terminal on the battery and see if theres a loose/unattatched wire there...

Car lost power during a drive. Battery is ok but there is no fire up. Sounds like there is no fuel coming into engine or there is no combustion / ignition.

Easy enough to check it out, you should be able to hear the fuel pump kick on when the key is turned, if you can't hear it, it might be the problem, but just to make sure, Squirt a little gas in the throttle and see if it will fire, usually even when the fuel pump goes bad the fuel will get into the injectors enough to fire it. Check it out.

Ran out of gas wont start now

if its petrol engine bang bottom of fuel tank while some one else cranks vehicle over if it starts good just pump jammed if it dont buzz to life and you cant hear fuel pump buzzing ceck for power to it if thats there replace pump. running out of fuel kills electric fuel pumps internally in petrol tanks.

if its diesel you must bleed fuel system taking extreme care if you un do lines some very high pressure

Nissan skyline 1988 .Noticed a petrol smell in and around back of car. looked underneath and there is petrol leaking out of the top of the petrol tank. Any suggestions please

A lot of Nissan models have an inspection cover in the trunk that you can remove to get at the fuel pump in the gas tank. If not there, perhaps under rear seat, but should be in trunk. Locate it, remove it and have a look for possibility of broken or cracked piece of fuel line hose attached to pump, or look around for other source of your leak. Careful with trouble light near fumes!! Use a good flashlight if you can. Be sure to relieve system pressure before doing anything on fuel lines if that's the problem.
