Can you hear the pump running? If not why not check for power to the pump on the grey wire. Get as close to the pump as possible. If there is power you just confirmed the fuse, relay, and wiring are all good.

The relay is located on the firewall behind the plastic cover that usually has something like electrical center written on it.

Wont idle or start without priming tbi


first check fuel pressure with a mechanical fuel gauge that attaches to fuel line schrader valve. around T.B.I. if no pressure with key on check fuel pump relay for correct operation, and also the oil pressure switch has the fuel circuit to it so possible oil pressure switch also. fuel pump has a check valve to keep fuel from going back to tank, so when u turn key on fuel pressure should go up within 1-2 seconds on gauge. if fuel pressure goes down quickly, possible bad fuel check valve, change fuel pump and fuel pump check valve (located right above fuel pump inside tank)

2002 GMC Sonoma 2.2l 4cyl. I have been having intermittent fuel pump problems. I replaced the fuel pump and now the truck will not start. There is spark and there is flow at the filter, but it is very...


With the ignition key turned on without trying to start the engine you should hear the fuel pump run for a few seconds. That is how its primed to start. Upon starting the oil pressure reaches normal operations & the prime switch will cut off by the signal from the computer. Thus the engine still needs fuel to run so the computer switches on the fuel pump relay to provide the fuel to the engine. The prime switch is intergrated with the oil pressure switch. If you do not hear the fuel pump upon having the key on replace the oil pressure sensor

1994 mazda b2300 turns over fine but won't start not getting fuel, i do not hear fuel pump when i turn key


There is a fuel pump "roll over" valve in the floorboard on the passenger side. It stops the fuel pump from running incase you roll the vehicle to prevent a fire. Check that the switch didn't trip from someone possibly kicking it or something. Then check any fuses or relays (swap relays if you have a spare or switch with the same on in a different slot). If everything checks out ok, then you probably need a fuel pump

I need a wiring schmatic for a 88 vw fox


The ignition switch and relay supply the power. Switch to relay, relay to pump. make a set of jumper wires and run them from battery to pump and see if pump runs . If it does its ok. Next pull fuel injection relay (under dash in fuse box)check it for burnt terminals , resistance and continuity. Its a good idea to get a shop manual for this car. This car is a pleasure to fix . After you pull relay for pump get a voltmeter and test the circuit for B+ (don't forget to put key in ignition and turn to the on position.
If you get B+ here switch is ok most likely relay is the culprit.
Remember there are two fuel pumps for this vehicle
One in the tank (accessable via trunk lift carpet and its in the right corner) the other under the car by the tank. have fun and good luck

I have a 1995 Dodge Neon with a 1999 motor in it. Recently it has had some issues starting. All I would have to do is just switch the relays (usually horn to fuel pump and vice versa) and it would start....


If switching relays got the car started for you before, maybe you had a relay that was sticking. Check the fuel pump relay & the ASD (Automatic Shutdown) relay. Either relay will keep the fuel pump from working. Listen for the fuel pump when you turn the key on. It should run for a few seconds & then stop.

poss. is fuel pressure reg. problem. put a guage on the test port and check press. should be above 35psi. see if it stays running when you spray choke cleaner in the pcv valve steadily while starting. if the engine stays running after a few seconds of running on choke cleaner then probably a bad fuel pump relay cause the oil pressure switch will keep the pump on without the relay when it has good oil pressure.
let me know if ya can do this or if it helps.
