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

    Excuse me, but what's with the "Thanks for Trying" rating?

    I gave advice based on the information you provided. Then asked for clarification on your problem so I could be more effective in finding a solution.

    I take pride in my rating percentage. The name 'Thanks For Trying' might be misleading. TFT is a negative rating, not a neutral one. If you aren't going to clarify your problem when asked, rate the solution helpful or don't rate it at all.

    Done venting.

    If you still are having troubles, let me know (preferably by answering the questions on my first response). You might find the results warrant a rating upgrade.

When i turn the key the engine cranks over but does not start, if i continue to crank it for a minute or two then it will eventually start and drive just fine. any ideas?


This sounds like a fuel system priming issue. When you first turn the key to the ON position (not cranking yet), you should hear a three-to-five second buzzing noise. This is the fuel pump running to pressurize the fuel system for cranking. This is controlled by the PCM and is relay activated. Once the vehicle starts and oil pressure rises, then the fuel pump is activated by the PCM via a different relay. If you can't start at first, what is probably happening is that the prime is not occurring and you have to crank it until the PCM sees oil pressure and then fires off the fuel pump. It could be PCM wiring or a bad fuel pump prime relay.

Put on new fuel pump got pressuer but want stay cranked


Your post is lacking any detail. However, if you are stating that the engine starts after being cranked but dies out (wont stay running) there are 2 ways the fuel pump is activated. When the key is first turned on, there is a 5 second fuel pump run (the ECM energizes the fuel pump relay). After the engine starts, the fuel pump relay will only stay energized when the oil pressure switch closes keeping the fuel pump relay on (oil pressure is above 5-7 psi). If the oil pressure switch is faulty or there is no oil pressure, the engine will stall just after starting.

No power to fuel pump on 92 olds silhoutte


The oil pressure sensor only keeps the pump running after the vehicle is started. If you turn key to on, the computer should signal to the fuel pump relay, turning the pump on for a couple of seconds to pressurize the fuel system. Then the computer signal stops. When the key is turned to start-cranking the engine- the computer again energizes the fuel pump relay, keeping the pump running until the engine starts.
If you have a voltmeter or test light, pull the relay out and check the relay terminals. One should be hot at all times-the power feed for the pump. The computer signal will be on the coil side of the relay-will have power for 2 or 3 seconds after key is turned to on. Or it will have a constant signal when the engine is cranking. If you can find both hot terminals at the relay, then start looking for a bad wire from relay to pump, or a bad ground for the pump, or a bad ground for the relay's coil side. Post back if unclear or other questions. When you pull the relay out, the diagram for it will be on the side of the relay-telling you which is the power feed and the terminal to the pump, and the coil side of relay, both the coil power side and the coil ground terminal.

1990 s-10 4 cylinder 2.5, 5 speed, throttle body injection, 120,000 miles won't start without stating fluid. Runs fine after started, I've changed fuel pump, filter, plugs. I appreciate any help.


My first question would be is the injector spraying when you crank it ?
The way its supposed to work, the fuel line to the tank should have about 10psi of pressure before you crank the engine. When you turn the key on the pump gets power for 3 seconds to boost the pressure. The pump stops working until the engine has oil pressure which takes a few seconds.
If the base fuel pressure leaks back to the tank, or the pump relay is not powering the pump, you won't have any fuel pressure or spray until you get oil pressure.

Cold start problem mazda 2001


Could be the fuel pump relay, or a faulty pump, or pressure regulator.
The fuel system is supposed to hold pressure after you turn the engine off. A faulty pump or pressure regulator could allow fuel to drain back into the tank overnight. You would need to crank the engine for several seconds to build pressure back up.
The relay could be faulty and not giving the fuel pump power until the oil pressure comes up.

1998 chevy astro van sometimes works, sometimes not.? At timesm rarely, the astro will crank but will not start. Fuel pump not cycling and making its hum noise so I changed the fuel pump with an AC Delco...


When you first turn on the key, no crank, the fuel pump should run for a few seconds then stop. There shows to be an oil pressure switch in parallel with the fuel pump relay. It's just a redundant power supply to the fuel pump. Once it cranks enough to bring up oil pressure and the switch closes, the pump will run even w/o the relay. Both the fuel pump relay and oil pressure switch get voltage from the ecm b fuse.
At the fuel pump connector, check voltage and ground, when problem is ongoing. Gray wire is voltage--black wire is ground.
You could pull the fuel pump relay, use jumper wire between terminals on load side of relay. The load side is that line with arrow head, when energized that line moves to the other terminal. As you can see, the orange wire is hot all the time, the gray wire carries voltage to fuel pump. If it runs with jumper, then check control side of relay, the control side has to have voltage and ground, dark green wire with white tracer is voltage comes from pcm. The black wire is ground.

Fuel pump won't run unless engine is cranking, but won't start


Are you sure it's running when cranking? It should have come on when key turned on.
This is for camrys up to year '91. It may apply in your '95, also. Check the 7.5 amp ignition fuse and the 15 amp EFI fuse and the EFI main relay, all located in the fuse box next to your battery. There is also the circuit opening relay tied in to fuel pump operation. It is usually found under center of dash. It is usually not the problem, but it is part of the checks for fuel pump operation.
If your car has a " check connector" or "service connector" (also called a fuel pump check connector) under hood on driver's side near the firewall (a little 1 inch cube with a cap on it), then bridge terminals +B and Fp with a jumper wire. Turn key to on (don't start car). The pump should come on. Listen for fuel return noise from the fuel pressure regulator, and verify pressure in hose from the fuel filter. If nothing, check those fuses above. Here is how power runs to pump: Battery to 40 amp main fusible link-to 15 amp EFI fuse-to EFI main relay-to circuit opening relay-to fuel pump-to ground. Ignition switch and the computer (ECU) work the relays to pass power to pump. Hope this helps some, Randy. 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.

Ive got a 1997 cavalier it will start but quickly dies out ive got fire to my plugs and fuel to the injectures ive just replaced the ignition switch is there somkind of a security


You need a new fuel pump relay. The engine fires up and runs off the oil pressure switch untill the oil pressure PSI is reached at normal operating conditions. When the oil pressure reaches its operating PSI the PCM or engines computer will shut off that circuit and turns on the fuel pump relay to run the fuel pump untill you shut the engine off

03 cavalier starts then dies


Generally when this happens all the time the fuel pump relay has gone bad. Upon starting any GM car up the fuel pump operates off the third wire on the oil pressure switch. When the oil pressure reaches operating pressure which happens in a few seconds the computer shuts off the current from the oil pressure sending unit and opens the circiut flow to the fuel pump relay. The relay will run ythe fuel pump until you shut the engine off. Replace the fuel pump relay and you shall have a good running car again
