I can not find the relay so i went to buy one to know what it looks like but i was told it does not have one, in the meen time i found a wiring diagram on the net from a parts store and it shows one, looks like the relay is wired from the coil and is mounted to the firewall, am i on the right track?

Power Accessory jack used to have power even with ignition off. Inside cabin Under hood main ignition fuse is good. Are there any fusible links in this circuit ??

main ignition fuse is only for just that...

if you checked that the circuit to that power outlet is OK, including the wiring, maybe the jack itself is bad

disconnect it, then use jumper wires to the battery to see if it powers on

Fuel pump wont run with key in on position,only when its cranking.

You know that how?

What testing told you that?

I would only be guessing (that is all we do here)

But it sounds as though the ignition switch is worn
& effects the fuel pump circuit, when in the on position,maybe!

Get yourself a wiring diagram & see how the system should work,
then test it at different points that are accessible

Not hearing fuel pump coming on. Checked relay, ok, Have power (using test light) to far right (standing behind car) wire (there are 5 wires counting the ground). I think I should have power to the...

Your fuel pump is powered by the GREEN fuse link in the fuse link holder. If you have 2 terminals (both WHITE/BLACK wires) at the fuel pump relay that is HOT all the time (even with the key OFF) then this fuse link is OK. There are no other fuses to be concerned with.

There is also a "Fuel Pump Control Unit" located on the left rear quarter panel, behind the "B" pillar. (See Picture)

Looking for location of fuel pump relay switch on a 1994 Honda Accord LX


Check for a 15A Fuse labeled FUEL PUMP on the cabin Fuse Box located in the front seating area, driver side, under dash, behind kick panel.

The diagram shows the Main PCM relay controlling the Fuel Pump, but it wont hurt to check the cabin fuse box under hood, passenger side, rear side of strut tower, mounted in fuse/relay box on firewall

I have a chevy van. I dropped the fuel tank to see if I had power coming to the pump and nothing. Tested the relay and that tests good

First check the fuse. Next test the wires from the pump back to the fuse block. It sounds like you have a broken wire.

1999 Meercury Sable. No electric to fuel pump

There are 2 fuses and a relay involved in this circuit but the lines that run power to the pump run partially exposed under the vehicle as well. Check the Interior Fuse, check the Fuse in the box under the hood and check to make sure you have voltage at the fuse under the hood. If these are good check for voltage on the wires going to the fuel pump at the fuel pump itself. You can do this with a multimeter and thumb tack. Use the thumb tack to puncture the insulation in the wires and test for voltage. If you don't have voltage there, start working your way back 12" at a time until you find the point where you have voltage to isolate the area of the break.

No power to the fuel pump at the tank checked all the fuses there is something i missed . i do not have a wireing diagram can you tell me where the fuse is

There will only be power for 2 to 3 seconds at the fuel pump after the key is turned to run position.Check the gray wire for power at the pump connector.
Do you hear the fuel pump relay click at the front engine compartment when you turn the key to run position.
The fuse should be under the hood,if not under the dash.

Check for a fuel pump fuse in the cabin or under the hood!
These fuses or relays as they are sometimes called usually look like 2 inch black square boxes!

Fuel pump system

There is power at the fuel pump for aprox 3 seconds as soon as the ignition switch is turned on
then it does not get power again until the engine starts

so if you are checking the power at the pump you need to have someone else in the car to turn on the switch while you are looking at your meter , you have a relay under the hood under a plastic cover at the fire wall that controls the power to the pump .
