SOURCE: need location of fuel pump relay

You are going to have to remove the fuel pump and disconnect the wire harness. Check for voltage at the plug. Not sure of the excact location.

Help... I have a 92 350 chevy truck that will not start. I have replace the ECM, coil, ignition mod., the fuel pump relay and the fuel pump. When i turn th Ignition switch on th fuel pump doesnt come on....


You said you jumped the wires for the pump? Was that at the pump relay?
If you have a voltmeter or test light, keep the jumper wire in place and check for voltage at the fuel tank connector. The pump wire will be gray. With relay out and jumpered there, you should have battery voltage at the fuel tank connector. The key doesn't even have to be on, cause the relay has voltage to it at all times. If you jumpered it right (terminals 87 and 30 on the relay), and no voltage at the tank connector, you have a broken fuel wire somewhere between the relay and the fuel tank.
If you do have voltage at the tank, but the pump still won't work, only two possibilities, a bad pump or the ground for the pump is lost. Check the pump ground first.

93 chevy caprice classic fuel pump relay


i would think if it were the relay you wouldn't hear the pump come on. I would unhook the fuel line just past the fuel filter. turn the key on long enough to see if the pump is pumping and is it getting past the filter. if it is you can rule out a possible clogged filter and you know the pump is pumping. I would then start looking for a clog. or locate the relay take it to the part store and get a new one. the problem is the relay only relays electrical signal to the pump that turns it on and off etc it doesn't tell it to pump or not pump gas so if you can hear it running it's not the relay

Turns over and over can hear fuel pump come on will start with starting fluid and runs great but when shut off for a little while wont start again only with starting fluid


If the starting fluid works then you have a fuel pump or a fuel pump relay issue. The fuel pump relay allows the pump to come on for about 2 secs and prime the fuel system. Once the engine starts then the power to the fuel pump runs through the oil pressure circuit.
If the car starts on starting fluid and then continues to run... I would lean toward a fuel pump relay issue. Hope this helps, Good Luck!

Fuel Pump Electrical Circuit
OPERATION
When the key is turned ON with out the engine running, the control module turns a fuel pump relay ON for two seconds. This builds up fuel pressure quickly. If the engine is not started within two seconds, the control module shuts the fuel pump OFF and waits until the engine starts. As soon as the engine is cranked, the control module turns the relay ON and runs the fuel pump.
When the engine is cranking or running, the control module receives the Crankshaft Position (CKP) sensor reference pulses which in turn energize the fuel injectors. As a back-up system to the fuel pump relay, the fuel pump can also be turned ON by a fuel pump oil pressure switch. When the
engine reaches about 28 kPa (4 psi), and the fuel pump relay does not complete the circuit, the fuel pump oil pressure switch will close to complete the circuit to run the fuel pump.

An inoperative fuel pump relay can result in long cranking times, particularly if the engine is cold. The fuel pump oil pressure switch will turn ON the fuel pump as soon as oil pressure reaches about 28 kPa (4 psi).



You can test to see if the relay it's self is bad by swapping it temporarily with another relay. If your truck has AC then that one should be compatible. Just compare the two to see if they're the same and if so, try using the AC's relay.

94 dodge grand caravan no fuel in fuel rail


Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe

1987 4.3L starting difficulty


First off, I'm a great believer in the simple solution. If jumping the relay works, then replace the relay.

As far as a relationship between fuel pump operation and oil pressure, coincidence of operation.

If the new relay fails you, I'll need some more info:
  • Fuel Injected? If you turn the key on (not to start) do you hear the fuel pump come on for a sec then shut off?
  • Hard to start when hot, cold, doesn't matter
  • When it does start, does it idle ok? erratically? High? Won't stay running? Dies immediately?
  • Does it blow smoke? Black? Blue? White?
  • When driving, does it lack power? Stumble? Stall?
Hope it's the relay
