The spark plugs were changed multiple times. The vehicle was taken to an independent mechanic who stated that the spark plugs should not be touched because they were Ford certified spark plugs and tear easily. A special onsite Ford mechanic repaired the spark plugs. The accelerator pedal and stalling failures were not repaired. The manufacturer and dealer were not made aware of the failures.

The failure mileage wasFord recall number 11S Vehicle was manufactured at Norfolk, va plant. My VIN was not included in the original or expanded recall; however, it is now exhibiting the same problem; airbag warning light flashes twice X five times, then remains on. Possible clockspring jumper wire chafing. Wear could cause electrical short and unexpected airbag inflation while driving. This first occurred about ten days ago, but then the vehicle sat in the driveway for eight days.

Current mileage is Today I called Ford customer service and was informed there was no warranty action or active recall that would cover this investigation and repair. I believe the recall should be further expanded to cover this incident. It began with vehicles made at the Norfolk va plant. Search CarComplaints.Cab 4WD. I believe my fuel pump relay is bad. Truck will crank but won't start.

Cannot hear pump running. I ran power to the fuel pump and got it started so I believe it's the fuel relay. I'm seeing that some people are saying this year truck the fuel relay switch is soldered into the fuse box and isn't interchangeable. Is this true? Do I have any other options than buying a new fuse box? New fuse box costs from the dealer. At the relay, unplug it, is terminal 30 hot, with engine cranking, It should be.

If so, you can use jumper wire between terminal 30 and terminal 87, the fuel pump should run. If it runs that usually means the problem is on control side of relay, voltage and ground.

The two top wires in diagram are voltage and both fuse protected. The voltage comes from pcm power relay. I'd want to check voltage and ground circuits for the relay before replacing.

Just my opinion. WHITE answered 3 years ago. The relay is hard wired into the fuse box. So I cannot take it out. I spoke to another person who told me that if I have power on 32,33,34 with the key on, then my relay should be fine I've changed the driver module and couldn't get it to start.

I put power to the pump and got it to start. Cannot figure out what the issue is. I have a model that began cranking and not starting on occasion and most recently will not start - it has no fuel pressure, relays K4 fuel pump and K PCM bench check O. Yes it would be nice to find a nice clearly legible electrical schematic of this circuit Not a diagram.

GuruW8FM9 answered 2 years ago. In checking my problem further I find my fuel pump circuit has 2. Digging into this more I find that one of my fuel tank straps has let go and maybe with the tank hanging down a bit it has pulled a connection loose??

Cheers " another old guy ". Anthony answered about a year ago. Qwerty answered 11 months ago. I found posts in other forums about a harness junction that's under the truck, driver seat.Recently changed out the fuel pump and alternator to this car once done noticed that there was a 15 amp fuse blown, replaced it, it controls the PCM, ECM, TCM, and fuel pump.

A girlfriend was driving it. Went to go get the car, installed a slightly larger fuse in place of the 15 started the car made it about a mile had to pull back over and then when I restarted it and back out the fuse blows again.

Had it towed replaced the fuse started. I want to make it safe for my girlfriend. Anybody can let me know? Do you. Hello, The reason your vehicle keeps blowing this fuse is that you have a short to ground somewhere in the circuit that this fuse protects. Also, you should never replace a blown fuse with one that has a higher amp rating.

The original fuse was put in place to protect whatever the load is for that circuit. If you replace a 15A fuse with a 30A fuse you could be allowing excess current to reach the device the 15A fuse was protecting, frying it. A short to ground works like this. The neat thing about automobile electrical circuits is that according to Ohm's law is one of the three electrical properties remains constant, than when one of the others rises the other must fall.

What am I talking about. The constant in this equation is voltage, or the force of the electricity. Your car battery supplies a nice constant So if you have a bare wire that is grounding out on the car frame, and not allowing all available voltage to be dropped across the circuit's load, resistance, or anything that opposes the electrical flow, goes down, meaning that current amps must go up. The current, or flow, of the electricity will continue to rise until it surpasses the rating of the fuse on the circuit and, pop, blows the fuse.

So, in the diagrams below I have given you the diagrams for the under hood fuse box and the Power Distribution Wiring Diagrams for your vehicle. Follow the circuit from the blown fuse and find the wire that is shorting to ground from the information below. Please get back to us with what you find out. Was this answer.
