Hi, there should be a black wire with a white stripe that provides ground directly to the pump. If that wire is grounded to the frame and connected to the pump, you have ground. Not sure where it connects on the frame.

Can't get gas to the motor, but there's a lot of gas in tank...


Need more info to answer your question better . But a couple of things could help you. When you turn the key on do your hear the hum of your fuel pump ? If so then that is working . If not check fuse panel next you will need to drop your tank and check your ground from the fuel pump to the frame ... some times you can get to the ground wire with out dropping the tank ... make sure it is clean if those don't work new fuel pump is needed . If you do hear the pump and you are not getting fuel then change your fuel filter

What can make a fuel pump not work attached to gas tank but work when conneted under the hood stight to the battery ?


Check the ground wire for the pump and see if it is grounded to the frame. Use the ohm setting on the voltmeter to do this. Or using the pigtail. Put the hot wire in the harness plug and ground the other to the frame, if it works, your ground is bad. You can trace it or just cut it and ground it close to the tank on the frame.

check all your GROUNDS, I can't express this enough, grounds @ tank, from top of pump, frame, check relay for fuel pump @ engine compartment, maybe on firewall ??? it may have a fuse. check all fuses, does pump HUM for (2) seconds when you turn key on ? listen for it, check all pump wiring front to back. along frame.

Just changed fuel pump in 95 gmc jimmy now it wont start where is the gas kill switch


when the key is turnned on do you hear the fuel pump run? if not find the ground wire or wires coming off the fuel pump they are bolted to the frame with a wire brush and or sand paper clean the frame and the wire eyelet for the ground and try restarting it If I'm not mistaken the fuel pump is in the gas tank and you should replace the sending unit as well as the fuel pump... Then check to make sure your getting fuel to your engine... If you are then it has to be spark/fire...lack of that is...Good Luck

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.

My gas gauge is really empty when it gets to half a tank is there a fuse I need to check I have an 02 s-10 blazer replaced fuel pump 2 years ago


Not a fuse if it reads any thing at all. Find the two wire harness that feeds your fuel pump and sending unit. It is near your fuel tank. It has a ground that goes to the frame near it. Unplug the connector and see what you gauge does. (key on) If you can determine the wire that becomes hot when the key is first turned on (feeds the fuel pump) put a ground to the other one to see if you get a change at your gauge.

Fuel pump keeps failing


check the fuel pressure first with a gague the pressure should be at 40-47 psi
does any other things stop working when the pump stops?
it sounds like you have a short to ground in the fuel pump circut, check the circut for any chaffed wires.... there is a fuse in the fuse box there is not supposed to be one on thr frame rail
another possibillity is a clogged fuel filter making the pump work harder and overheating
check pressure wires and replace the filter one of these is your problem
let me know dant forget to rate me
