It is fuel injected & what engine? They did use an Enertia switch on some , have you located that? I'll see if I can find normal location & get back, in meantime check near kick panels (by drivers left foot & passengers right foot) on drivers & passenger side, for a switch with a small push down to reset, button on top.

    Look for a brown wire from fuel pump relay. It may go to Impact switch, or also referred to as inertia switch, and coming out of inertia switch should be a red/with white wire which goes to fuel pump/sending unit assy.

    Check up on firewall inside on drivers side above where carpet runs up to. Push plunger down to reset.

1986 ford f150 tested fuel pump with cables,pump runs no power when hooked to wires going to tank, is it relay


THIS IS ALL ON MEMORY SO GET YOURSELF A WIRING DIAGRAM FOR THAT TRUCK!!!
If you have one you should install an inline fuel pressure gauge to verify that you are indeed not getting fuel pressure first. Assuming you have no fuel pressure, it could be one of a few things.
check all of you fuses
if ok, check fuel pump relay for activation during engine cranking. I believe in that vintage Ford, the oil pressure switch is responsible for activating the relay. So with a test light backprobe the activation wire at the relay. if you get activation power at the relay, and no relay activation, then yes it is the relay, but if you get nothing, then it will be the oil pressure switch. If you get activation to relay and still no pump activation then you might have a break in the wiring OR the fuel pump has short brushes.

I know thats alot to take in but hey thats what a diy forum is for right? Good luck!!!

92 F-350, 460 auto, two tanks/pumps. I have no current to either pump. Fuses and relays are good. A hot wire to pump turns pump on. Not seeing a switching valve, just the dash selector switch. Bypassing...


if the fuses and relays are good then have you check the dash switch,you may have to check the wiring(powers)from the pump back through the system until you find were you have lost power.

Im working on a 1986 toyota pickup 2.4l efi non turbo 4x4 i replaced the head gasket and i have a black wire coming from the intake wiring harness that has no plug on it .if i touch this wire to a hot wire...


Sounds like this wire should operate the electric fuel pump through the fuel pump relay.The fuel pump relay should start the fuel pump to maintain fuel supply to the common fuel rail and any surplus fuel will be bleed back to tank by pressure control.The injector opening sequence is contolled by computer once the engine is properly timed.
If you say the engine runs for a few seconds it would indicate fuel pump or relay is not getting power to operate or fuel pump is not delivering enough pressure to feed the injectors

Bronco turns over but not getting fuel tank pump no noise or high pressure pump no noise 1986


Bronco V8 ?????Check for voltage at the Inertia Switch, it it has power, then the fuel pump may be bad. If no power then check the fuel pump relay and fuse. The yellow wire should have power when trying to start i tis powered from the relay which gets power from a fusible link at the starter solenoid (yellow wire, fusible link)

No power to fuel pump


You might want to check out the relay if the fuse is good. It should be located under the dash. Otherwise connect the fuel pump directly to the battery to see if the pump will run if it does check the wires that goes to the pump, the ground wires and the wires that connect to the ECU.

Hope you can read it, the load side of relay gets voltage from fusible link. The load side of relay is that line with arrowhead, showing open switch on left side of relay in diagram.
