No power to fuse box or ignition.

Ignition/run circuit short to power, safety belt lamp circuit short. Where might these all com into contact?

Hello I have a 07 f150 that died out at the light and would not restart. Replaced battery which was 9 years old and done for. I have checked fuel which I’m getting it is reading at range on scanner. Crankshaft, cam sensors are good. Ignition module is good, I checked fuses believe all the ones I needed. Swapped pcm fuse with another. I I have no spark to any cylinder. Starting fluid did nothing as well. Will crank but not start.

Change spark plugs and coil packs and fuel pump car will crank but no start no spark not getting power to my fuse box

Has power with overdrive off but hesitates and Boggs down when going up hill with overdrive on and acts sluggish when cruising at low speeds with overdrive on. When you step on the gas halfway to the floor or more it Boggs way down before accelerating. I have replaced all 8 coils all 8 spark plugs fuel filter both evap valves and the fuel pump control module and cleaned the mass airflow sensor and dumped fuel system cleaner in the tank.

Esof not working ,when u switch the dash selector switch nothing happens found that the 2wd vaccum valve [under Hood] never drops out and the 4wd valve never turns on. There isn't any clicking noise indicating that any relays r trying to work also found resistance values at dash switch 3k for 2h, 1k for 4h and 300 for 4l what should the voltage be at switch i have the constant 12v on the coils for the vaccum valves but the gnd is not switching to turn the 2w off and the 4w valve on

It started with jerks while driving; when starting gold y vibrates and then it normalizes. While driving it losed power as if choking a little, but now it got worse. It chokes while accelerating and sounds as if exploding, when I let go it keeps driving; if I accelerate again it does the same but it doesn't stall. If I turn it off for 5 seconds it works for 10 minutes and then it fails again. I alreadi cleaned the injectors, changed spark plugs, air filter, fuel filter, fuel pump, coils and their sensors. I've already had this problem for a year and they can't solve it, yesterday I scanned it and had air sensor error, but changing it didn't fix it.

I just bought this 05 f150,the guy I got it from said he replaced the fuel pump , coils, spark plugs, it will start if you spray it with some starting fluid and will run between 5&20 minutes then dies and will not restart for several hours even with starting fluid.

My vehicle jerks and stalls while driving, usually when I speed it up. I've already chan the gas filter, the catalytic converter, the gas regulator, spark plugs, wiring and coils. Even though the jerking problem is not as worse as it used to be, the car still stalls. Can anyone help me please?

Got gas and then the problems started. Changed out 5 coil packs, all new plugs. New purge control valve. New fuel pump. Checked fuses and relay. Truck will start, rev up and then die. I hear a clicking sound near the kick panel fuse box just before it dies. Snap-On scanner is showing Code B10F1

No power to coilpacks cranks no start

Seems To Skip But Feels Like A Shudder Have Replaced Plugs , #1 coil fuel filter trans And differentel speed sensors gas cap had a p0500 code and emission code

I parked my truck A/C was working fine. Next morning started it up no A/C. After I did some troubleshooting the determination is fuse 30 (A/C clutch power10 A) in the power distribution box is good. I dig up some wiring diagrams and start through it. The load side of fuse 30 should have a internal (in the power distribution box) jumper to pin 3 (switch leg) on relay # 23 (fan clutch relay). I start it up, turn A/C on, I pull relay 23, check pin 3 nothing there. I go ahead and run thru the rest of the circuits. Relay 23 coil pin 1 is hot, I check pin 1 to pin 2 I show power across pin 1 and pin… Read complete

The fuse number 33 gets blown. I already checked coils and oxygen sensors, everything looks normal. There are no cables making a short circuit, and I also checked the gearbox harness. Scanning it gives codes for shift solenoid a and b, but the gearbox seems to work fine. What could it be?

Check engine light was on so had auto zone run a scan on it. And at that time my truck would barley creep down the road. Well holy crap a ton of codes parked it till was able to slowly work on it. First changed all spark plugs helped a little then all 8 coil packs. New throttle body new EGR valve. Got a little better new fuel filter. Still ruff idle and cutting out on exceleration. Used smoke machine to check vacuum leaks didn't see any smoke. Checked vacuum line from brake booster that hooks to back of intake seems intact. Brake light stays on mostly sometimes flashes on and off. I'm at a loss help me figure this out. Plz

Good afernoon, I own a Ford 150 fx4 2007 and recently I've changed both VCT (Variable Camshaft Timing), pinions and roller chains, a camshaft, spark plugs and coils. I have as well changed the oil but the engine is now giving off a sound at low revs, as if those chains were touching themselves.Even more, if I drive in reverse, the car usually starts trembling and, in order to stop it, I need to desaccelerate or stop it. No failure is provided by the computer, any ideas?

No power to low pressure fuel pump. No power coil - fuses test fine

I have a 97 f150 xlt I recently replaced the engine for similar one I have power going to the coil but nothing coming out. I have replaced coils but is not the problem. Please help. I am going to cut wires off the electric starter hoping that will help. Engine turns over

I have changed the coil-packs, wires, plugs, egr value, & sensor. I have cleaned the injectors on #1 & #2 changed them around. After doing all this I'm not getting any fire in #2 and the above symptoms
I don't know what else to do.

Engine was running fine while warming it up on a cold. After 15 min of running i was about to put it in gear and it just died and would not refire. I began to diagnose by checking for spark at plugs, none, fuel rail pressure, none, all the fuses are good and the breaker for the fuel pump is good. I have power on 1 side of the ignition coil but none on the other when cranking over. I have no power to the fuel pump but i have it at the fuse and relay. After it died I thought I smelled smoke in the cab but cant find anything burnt. I removed the ECM and it smells a little like it but i'm not sure… Read complete

Can't seem to get rid of what is like a miss spitting and sputtering no power just changed coil pks they were aftermarket, along with injectors
Checked all the vacuum lines getting po1701 and 1704 codes and can't find or where to narrow it down

So I have a Ford F-150 and I have literally replaced both camshaft position sensors the crankshaft position sensor I have also replaced the fuel pump driver module I've replaced all the spark plugs all the coil packs and for some reason it's still bogs down when I come to a stop it will bog down and start to sound like a diesel does anybody have any suggestions

Okay the truck doesn't want to run right it's like it's got no power you can feel it misfire your kick in and off I've got a new ECM I got a new injectors I got a new coil packs I got a new tank I got a new fuel pressure regulator I got a new fuel pump I've got new coil packs new spark plugs cam sensor crank sensor the differential pressure feedback sensor throttle body positioner sensor all this has all been put in here pretty much all new stuff even replace the wiring harness from the ECM out to the engine plug and play can't figure out why it doesn't want to run down the road very good it'll be fine unless it's an electrical issue

I have a 2009 ford f150 xlt when i start the truck it will run great drives great,but when it reaches operating temperature it runs really rough it cant hold the same speed with out chugging and the motor sounds like a diesel knocking but smooths out,motor runs very erratic,only when it reaches operating temp,i had many auto shop tell me it was plugs,coil packs,timing,fuel pump fuse relocation,I had all the things listed repaired it has costed thousands of dollars and its still not running the correct way i dont know what else I can do can someone help me please is there anyone else out there having this problem if i resolve this problem ill post what was wrong with it,im hoping someone can help

Installed new zero mile engine. Have power and proper grounding, new starter, new fuse box, new coil packs, new plugs. Turns on but will not crank

My 99’ f150 shut off while driving and when I try to start it I blow a 30a fuse under the dash as soon as I turn the key. Would a bad coil cause this?

1994 5.0 showtruck diegoing down road no fire no fuel won't start,replaced coil still no start

I have a 1994 of 150 and I have replaced the spark plugs wires throttle positioning sensor clean the throttle body remove both cats and put a piece a straight pipe in their place and also replaced the Ignition coil and clean the mass air flow sensor and still the truck doesn't react to me pressing the throttle until I have it to the floor and just recently I started backfiring.

Runs smooth in park. Looses power going down the road, starts popping, will not accelerate, stays on but will not accelerate. Changed coils, plugs, wires ,cam position,egr, vacuum linesMAF.

New plugs, new coils. Im getting the notorious p300 code. If speed limit is 55 ill get to speed and then try to maintain 55mph lightly on the gas pedal... Ca -put ca- put put!! The misfire happens. Get on gas a bit more and it stops! Ive almost had it with this F.O.R.D 5.4 3v nightmare! Help!! Please

My truck has the wrench light on the dash. I had the transmission serviced recently and the coils replaced. Also did an oil change. I replaced my mass air flow sensor myself.

The truck will crank but has no power to coil ignition module or fuel shutoff switch (inertial) we hav jumped between 2 and 6 in the eec connector and still no power to switch checked main ignition switch and all wires have power in the run position found a bad wire to main fuse panel under hood to the # 22 fuse repaired and restored power. Had ignition mod. Tested used noid light on injectors verified spark replaced all 6 injectors verified base timing and plug wire location HAVE Questions about noid light test seems the light is blinking way to fast when cranking like its seeing every cylinder pulse signal not just the one I am connected to ???
