I HAD THE SAME PROBLEM. I FIRST REPLACED THE FUEL PUMP IN THE TANK. THEN WHEN IT STILL WOULDN'T START. I WENT THROUGH THE FUSES. I FOUND A GREEN 30 AMP FUSE IN A FUSE BANK IN THE ENGINE (DRVRS SIDE, UP BY THE FIREWALL) THAT WAS BAD. I REPLACED THAT FUSE, THE PUMP GOT POWER, AND THE CAR STARTED. ALSO, THERE IS A "MULI-RELAY" SWITCH IN 92 SABLES THAT IS MOUNTED RIGHT AT THE FRONT OF THE ENGINE. IT LOOKS LIKE A 5" X 5" METAL BOX WITH A HUGE WIRE HARNESS ATTACHED TO IT. THAT HARNESS HAS A BOLT INSERTED IN THE MIDDLE OF IT, SO YOU CAN'T MISS IT. THAT RELAY WILL ALSO CONTROL THE FUEL PUMP. UR BEST BET ON THOSE IS TO GET ONE FROM A JUNK YARD. I GOT ONE OFF OF A 1993 TAURUS AND IT WORKS FINE. IF YOU GET THEM FROM A DEALER OR PARTS STORE THE ARE USUALLY OVER $100.00. THE JUNK YARD CHARGED ME $35.

HOPE THIS HELPS...STEVE PHX AZ

SOURCE: fuel pump on my 1987 ford ranger has no power

There is a Fuel Pump relay. Not sure if Ford has a Relay Box under the Hood though. There are also Fuses that Control some items of the Fuel System. Try the Relays first and see what you have.

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

check for voltage at the pump. If it has 12v there, (and a good ground) then pump is bad. there may be a pump fuse on the fuse block (can't remember) but if you find it has blown, the pump may be getting ready to fail. If fuse fixes the problem, replace it and carry an extra with you, then change the pump.

SOURCE: no power at fuel pump chev.S-10 looking for fuel pump relay and fuse

The fuel pump relay is located Under hood, driver side, upper firewall, mounted in relay block.

The fuse is located under the instrument panel to the left of the steering column. The fuse block should be visible from underneath the steering column, near the pedal bracket. If the panel is not visible, check for a removable compartment door or trim panel which may be used on later models to hide the block.

Why want my 93 ford ranger pick up start without pouring gas into the intake fuel pump want come on unless hot wired straight to batt


There is a fuel shut off switch (inertia fuel shut off-opens on impact) in the wiring between the fuel pump relay (in the under-hood fuse/relay box) and the gas tank. It may have opened. I don't know where it is located, it may be behind a kick panel under the dash. You may have to ask someone where it is.

The fuel pump fuse is a 20amp fuse, also in the engine compartment fuse/relay box. This fuse and it's wire is the power feed for the fuel pump relay.

WHHY IS THERE NO POWER GOING TO THE FUEL PUMP RELAY OR THE CHECK RELAY


sometimes its because of an aftermarket alarm system or a natural gas system. they both latch on to that circuit to deactivate the pump.

Cant find the fuel pump fuse in a 2002 galant


Your vehicle actually has two fuel pump relay's ! You can view fuse box diagram here http://www.bbbind.com/free_tsb.html Enter your vehicle info. year , make , model and engine size . Under system click on electrical distribution ,then under subsystem click on junction block . Then click on the search button , then the first blue link . Scroll down you'll see fuse box diagram . Do you know how to do electrical testing where the relay plug's into the junction box ? Check for B+ voltage , control from the PCM / ECM or ECU what ever Mitsubishi call's the engine computer . The computer will energize the fuel pump for two seconds to prime the fuel system , it won't turn it on again untill it see's a input from the crankshaft position sensor while cranking the engine. Videos on youtube testing fuel pump electrical circuit .

My 1998 S-10 is not getting gas to the throttle body. I can pour gas down the throttle body and it will turn start and I am able to drive for miles. Once I turn it off, I have to repeat the process of pour...


when you first turn the key on you should hear the fuel pump run for about 10 seconds . this primes the fuel system .If you do not hear the pump run then you need to check the circuits for the pump
the fuel pump has a fuse and a relay that is use to power up the pump . you should check the fuse and if they are ok then switch the fuel pump relay with a like one in the fuse box (horn relay is the same as the fuel pump relay ) I think the fuse and the relay are both in the under hood fuse box on your truck . If these all check out ok then you need to check for power and ground at the fuel pump connector . if this checks out all good then replace the fuel pump . some times if you think the pump is not working you can bang on the gas tank with a rubber mallet this may move the pump winding off of the dead spot and the truck will start ... but this is not a fix .. just a way to get it started to move it or take it to a shop

I shut the engine off. tried restarting, failed to do so, seems like not getting fuel. Is there a fuse for the fuel pump. It was on empty and I did add 1.5 ga gas


When you shut the engine off then it was not out of gas and there is a fuel fuse in the fuse panel and a fuse relay in the engine compartment. The fuse and relay box is always near the battery. It sounds like by the information I gathered so far is the fuel pump was sucking most of bottom gas which is always dirty gas and probably plugged the fuel filter. Make sure the to have someone listen if the fuel pump works by listening under the fuel tank while the ignition is turned on but not the starter.
1. Listen for a humming noise near the tank while someone turns the key on.
2. If the fuel pump makes is on then its your fuel filter.
3. If no sound then its your fuel pump. Start with the fuses then your relays and if they are all in working then its time to change your fuel pump.
( note: sometimes its just the way the car is sitting and tilting where all the fuel is unreachable for the pump and you might have to put more gas.) Hope this works. Cam

Car is not getting gas to motor even after new fuel filter is installed


If you change the fuel filter and still not getting fuel to the engine, then the other possible problems are:
- Clogged fuel lines due to 'dirty' fuel.
- Defective Fuel Pump which may not provide enough pressure to 'push' the fuel pass your new filter.

Hope it helps.

Engine started and died. Will not restart. Seems to be electrical issue - what fuses or relays should be checked? Thanks.


Does it run if you put gas into the throttle body? If so, then it may be a fuel pump going bad, or the circuit to the fuel pump is dead.

Test for power at the fuel pump, then, when ignition key is on.

Test for pressure of fuel using a gauge at the fuel rail.

Basic Fuel System Diagnosis Two of the most import diagnostic checks, when dealing with a driveability problem involve the ignition and the fuel systems. The questions most technicians attempt to answer first are "is there spark?'' and "is there fuel?'' This often leads to solving most basic problems. For ignition system diagnostic testing, please refer to the information on engine electrical components and ignition systems found earlier in this manual. If the ignition system checks out (there is spark), then you must determine if the fuel system is operating properly (is there fuel?).
