SOURCE: 1991 ford f150 no noise from fuel pump and truck will not start

get a code reader like the Actron CP9015 Code Scanner, 20 dollars and will flash codes. if it will not diagnose itself, the ecm must be replaced. this fixed my dads truck with the same problem

The relay is more than likely in the fuse box under your hood.

I would check that box first, then the inside one.

I think it's in the battery box, I know in the older models it was there, number 301.

Did you check the fuel inertia switch in the passenger side kick panel ?

The fuel pump is powered :
the fuse to the fuel pump relay.
The fuel pump relay to the fuel inertia switch
The fuel inertia switch to the fuel pump itself.

At the fuel inertia switch in the kick panel, power from the relay is the Dark Green w/ Yellow stripe wire and the pink w/ black stripe wire is the power. from the fuel inertia switch to the fuel pump.

If you jumper the fuel pump relay, you should hear it run. If not pull the fuel pump relay, and check the pins in the relay socket, pin 30 should be the power from the fuse.

If you have power at pin #30, jumper the relay socket as shown with the red line above, and check the dark green w/ yellow stripe wire at the fuel inertia switch for power.
Press the button on the top of the fuel inertia switch, and check for power leaving the fuel inertia switch on the pink w/ black stripe wire.

This is tests good, check for power at the fuel pump, same pink w/ black stripe wire.
Fuel inertia switch info is in the owners manual, If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

Not sure I am following your story, but here goes.
The fuel pump relay gets power from a fuseable link at the starter solenoid and from the EEC relay. When the fuel pump is grounded by the computer it sends power to the inertia switch then to the pumps and controls.
If you are not getting main power to the relay the fuseable link (yellow wire) is fried. If the pump relay is not engaging, the EEC relay could be toast (red wire). If you are getting power out of the relay but not to the pumps, the inertia switch may be tripped.

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!!!

I have 1986 Alfa Spider that won't start. Car has been sitting for a year. I replaced battery, fuel tank, fuel sender unit, both fuel pumps. I seems that the in tank pumps is not getting any po


Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.

Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.

Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

1986 toyota camry fuel pump doesn't receive power, where is relay located?


The typical placement for the relay is under hood, mounted to wheel well, it may be on either side. Look for rectangular plastic case about 3" w by 8" l with wires attached. To access look for clips holding top cover on pry clips out and remove cover. Relays are about 1.2" square, usually black, and can be removed by pulling directly up. Relay diagram should be on inside of cover. There will be more than one (sometimes as many as 8) and if diagram is missing have a helper turn ignition on and listen for a click to narrow down which relay it is. Often times all relays are the same and you can pull one out and swap it with another to see if pump will work. Good Luck.
