Did you check the fuse for the fuel pump you don`t say.there is also a fuel pump relay in the system.if you bypass the system then the ecm won`t have control for the pump,which controls the 2 second prime at the beginning when key turned on and it won`t shut off the pump in case of an accident when the engine stops.you can bypass it but its not recommended because this.if you do bypass make sure you have a 25amp fuse wired into the power wire and a on/off switch that you must remember to turn on and off every time you drive the car.

You need to troubleshoot the relay and terminals. First try a different relay. Another relay in your car may be same part number relay as you pump relay, so check for that. Swap in a known good relay and try it.
If no help, look at relay. Is it 4 terminal or 5 terminal? If 4 terminal, easier to check. One terminal will be your power source, and hot at all times, so check for that-use your jumper wire (if no testlight or voltmeter), stick end in terminal and just touch metal, looking for spark indicating power. If no terminal has power, maybe only hot with key on, so turn key on and check for power. If no power, the feed from battery to fuse block is lost. If you have one power source, another terminal will be to the pump, the one you turned pump on with. Terminals 3 and 4 will be the signaling source to turn relay on through coil side of relay, and a terminal to ground, also on the coil side of relay. If you have constant power on one terminal, check for the signaling power. When the car is cranking over, the signal terminal should be hot-the signal will be coming from engine computer. So when cranking, relay socket should have two hot terminals. If you don't have two, you're right, relay is not getting correct power to the fuse block. BTW, don't use jumper wire to check for signaling source, use a testlight. Don't want to cause spark from computer wire.
What is EGI? Not familiar with that.

Fuel Pump wiring


If I understand right, I would say the normal ground for the pump is bad.
"I am guessing the pump uses a ground source to start." well, just the normal ground like for any motor, you have the power wire (gray) to the pump, then the ground wire for pump, does it branch off near the tank and find a ground? Or does it go into the tank connector and then routed back somewhere through the wiring harness? Anyway, it has to go to ground somewhere. You have the wiring right it sounds,. just make a good ground source, or find the original ground and repair it.

1991 tracker I put in a new fuel pump relay. the new relay has power comming to teh relay the wire going to the fuel pump has no power. put the jumper wire in and the pump runs. Why won"t the power go...


probably becuase its faulty...try replacing it and go from there...or else there is another source of resistance in the circuit some where....also, check your fuses....a blown fuse will stop flow of current as well.

93 volvo 850 no power at fuel pump but power at fuse and relay


Sounds like you have a broken wire between the fuse box and the pump..
Check colour on the pump wire and trace back to box.. if you cannot find it and its only the pump playing up run a new wire from the FEED side of fuse to the pump but remove the old wire before connection up.. Or use a test light to find the short in old power line..
Let me know how you go Ron

Have no voltage to fuel pump. have checked fuse, relay, and replaced fuel oil pressure switch. still nothing


You are checking on the gray wire at the pump.
This wire will ONLY have power for 2 to 3 seconds after key is turned to run position after key has been OFF for 10 seconds.
.....or when there is oil pressure.
If you do not have power under these conditions.....run a new FUSED power wire to the pump/pump wiring that has only power when the key is on.
The other way to fix this is usually a rewire of the relay center/fuse box to supply power to the fuel pump relay when the key is on.

No power to fuel pump on 99 chevy venture


If you do not have power on the GRAY wire at the fuel pump.........
switch the fuel relay with a same type good relay in the relay box and check for power again.
REMEMBER ...YOU WILL ONLY HAVE POWER 2 OR 3 SECONDS AT PUMP AFTER KEY IS TURNED TO RUN POSITION......after key has been off for 10 seconds.(or when there is oil pressure)
If no power in the gray wire at this point and you have checked ALL fuses in engine compartment and on right (pass ) side of dash panel facing pass door.......add your own jumper to supply power to system at fuel pump fuse and test again.........if power at pump now....install a permanent jumper (SWITCHED POWER....OFF WITH KEY) at fuse box......if still no power check all connections between fuse box and pump.....or run new power feed wire to pump gray wire and disconnect old.

2000 S10 4.3L Fuel pump stopped working out of the blue. We Put a new Fuel Pump in, new harnes to fuel pump, new fuel filter, new relay, new fuses in IGN C and ECM B fuses. Still the pump will not turn on....


Did you verify that the relay terminals have the appropriate signals to them? 

ECM fuse B (20-amp) should provide power at all times to the orange wire of the fuel pump relay. The relay coil receives ground via the black wire, and relay coil gets power from the dark green/white wire. When the relay is closed, you should have battery power on the gray wire. 

The relay trigger wire should have power from the dark green/white wire in terminal 1 of the Vehicle Control Module (VCM) connector for the first couple of seconds after they key is turned to run (to prime the system) and when the truck is running. Checking for all the appropriate signals at the relay is where I would start. That is after I checked for diagnostic codes.

Believe the fuel relay is the middle relay out of the three in the left rear of the glove box. Last thing is to hot wire the fuel pump if you can not get it scanned, see if the pump is bad unless your going to have a shop work on changing the fuel pump.
Good luck and hope this helps. keep me posted.
