There should be some over-sized fuses in a fuse block under the hood. Often they are on the firewall, behind a cover or near the battery in a fuse box. It's all just a guess since there isn't enough information to figure out what's really going on. There is a "lock out" in the control module. Disconnect the battery. disconnect the control module. Wait. reconnect the control module. reconnect the battery. Voltages should be correct. If that does not help below is a link for fuses:

may be the crank senor also as if it doesn't sense spark it will not engage relays. Hope this helped Tim

My ba xr8 ute fuel pump starts going on its own when there is no keys in the ignition. when i put the keys in and turn on it stops. any ideas


I would replace the fuel pump relay, the diode inside the relay is likely defective and this allow the relay closing coil to energize and turn the pump on, the repay is under the hood I think in the fuse and relay center.

I put in fuel pump, replaced the relays, and also put in fuel filter. Tried running a diagnostic on it but it seems the plug isn't getting power either. There is no fuel getting to the P71 motor.


The problem with the ALDL connector could be the cig lighter fuse.
Do you have power to the fuel pump relay ?
Will the pump run if you jumper the relay ?
Do you have power and ground pulse to the injectors ?

No fuel pressure in efi system


Either the fuel pump is not working, or the filter is totally blocked.
The fuel pump circuit needs checked to see if it's a wiring problem or a failed fuel pump. There will be (probably) a fuel pump fuse in your fuse block, and a fuel pump relay under the hood.
If you check the fuel pump wire for power at the gas tank connector while the engine is cranking over, and there is power there, and the ground for the pump is good, then the pump is not working and will have to be replaced. If you do not have power when cranking, the wiring at the fuel pump relay will have to be checked. Simple relay- has a power feed for the pump at one relay terminal (it is hot at all times), and a fuel pump wire to pump on another terminal (the power out for relay). When relay coil side is energized from a signal from computer, the relay contacts close and power is sent to the pump. The other relay terminal is a ground for the coil side of relay. Pull the relay out and you will see the diagram etched on it. If there is a fifth terminal, that could be a pump prime terminal, or a way to keep the pump running when engine is running through the oil pressure switch. But when cranking the engine, the computer will signal the relay to send power to the pump.

2000 rodeo will not crank checked fuel pump and relays they are good .When I bypass relay it runs fine anyone know whats wrong


Sounds like the relay isn't receiving it's signal power to close and activate the main power to the fuel pump. Test to make sure it's getting the power when you first turn on the key [ The PCM will turn it off after a few seconds if it dosen't sense a imput from the Crank Sensor that the engine is running ]. If there's no power there, first look for a blown fuse and make sure there's power to the fuse, if not then you will have to test back thru the circuit to find the cause [ also check the igntion switch].

My buick park avenue wont start, i think its a fuel pump relay


the relay can be found in the fuse box thats located under the hood open the box and look for the fuse or relay that says fuel pump. this fuse box is usually on the drivers side of the vehicle but it can also be on the passenger side.

1994 buick park avenue . driving home and shut off


how did you jump the fuel pump relay, by bypassing the relay or by applying power to contact that closes the relay? If you bypassed the relay completely you need to b ench test the relay you can do this easily by using any 12v dc power source. If you tested the fuel pump relay by applying power to the relay and the pump run and developed pressure. I suspect a wiring or ground issue. Good luck

1991 camaro RS Fuel pump not working- no power to pump


If the oil pressure switch has two wires on it it may be one that shuts down the pump. I'm not positive but I think it completes a ground circuit, not the hot side though (but may run through a relay.) There should be a pump relay under the hood with a group of other relays. I don't have a wiring diagram for your car but you can get a basic diagram in most inexpensive manuals. They wont usually give you locations but at least you can get an idea of how the system works. There usually is a fuse. If the fuse block is not labeled, use a test light and probe the back of every fuse for power with the key on (takes about ten minutes and faster than trying to find info) change any that are blown. The most likely culprit is a relay, so after testing fuses look for it. (usually on drivers fender or on right side near firewall.) Worst case, trace the power lead all the way through the harness 'till you find where power begins.Testing is important here...I could give you much better info if I was there to do it for you. Most important is to stay "on track" till you find the place where power ends. Don't jump all over the place or you will end up doing an incomplete test.

First, check with the key on to see if you have power to the pump, if no power then we'll look elsewhere, Some solutions could be a faulty pump Or Inertia switch, but that does not match with having to tap the fuse box to start it, Also, remove the fuel pump relay and with the key on test for power to the relay, this can be done with a simple test light.

Not getting any Fuel


Check the fuse and relay for the fuel pump if they check out ok then its either the pump or the wiring.(heres a simple check to determine if the fuel pump is working or not...In a quiet area remove the fuel cap then have someone turn the key to run(not start) keep your ear close to the opening of the fuel filler neck and listen for a buzzing or whirring noise) another way to check for fuel is to remove the cap on the fuel pressure relief valve (with the key in the run position) depress the stem of the relief valve with a screw driver or a key (stand Clear!) if fuel spurts from the relief valve opening then your problem is elsewhere.
hope this helps.....Good luck!
