Ford Wiring/Electrical :: 2008 F150 - Cold No Crank / No Start
Feb 13, 2013
I have an 08 F150 5.4L with about 68k miles. When the temperature is 40 degrees or colder it will not crank. I had the same issue with my 2005. I can turn the key and nothing, lights, radio and everything work. The dash display has dashes all the across for the miles, temp and compass. I have found out that it doesn't matter if I leave the key forward in the run position or try to crank, it won't do anything.
Battery is good and no problems with the truck. After the key is in and I give it anywhere from 15 to 60 seconds you can hear an electrical click real faintly and see the red security light come on and then the computer display comes on and then I can start with no problem? What could this be? My dealership has no clues and I can get it to act up because after I get it there it starts with no issue. The remotes work fine and this issue was why I got rid of my '05.

I've been trying to trace down a issue with the airbag warning light flashing. The seatbelt light is flashing also. The airbag code is 53. If i search it i get the front crash sensor..I replaced it with a new sensor and pigtail. Other than that the search leads me to believe it could be anything.
I've checked and clean every connection that i could find. I haven't removed the center console yet to check the module. I did buy the truck last fall as a winter/work truck. The issue started a couple of months after i started driving it. Not sure if the module would just go bad.

My 85 f150 5L is parked to far in into my alley.. the last time i saw my keys i moved it up to water the plants that it was tucked almost on top of.
ive been looking for the keys for 2 months.. the truck isnt being driven at all but i think my neighbors are getting mad at it being out so far.
I can get in the engine bay, and i have jumped the starter on our big trucks at work before.. but what wires do i have to join to put the ignition into the run position?

Start out, drive about 20 minutes, get on the Interstate and the battery light comes on 2008 F 150 5.4L 4X4 - 57K miles..... get to my destination, went about 20 miles, turn around to come home, without turning the truck off because of the battery light being on and I notice the charging gauge drifting down to the left, get back on the Interstate and the wipers are slowing down and lights on the dash are dimming.....go around 15 more minutes I lose all lights on dash, wipers, defroster everything, charging gauge is now pegged all the way down to the left and the truck is starting to act up running like crap so I barely make it off the Interstate and call a flatbed, I guess I was about an hour into the trip ..... battery is only about a year old and it started fine that morning and the day before when it was about 12 degrees ...... dealership had the truck, just gave me a call and said they can't find anything ?? ..... never a days problem since I bought it new in late 07' ....

2000 XLT F150 4.6 - New starter & solenoid(s), battery cable & fuse links good.
When i turn the key, I hear one single click and the power cuts out entirely. I can't attempt a second start or turn on the lights or have any power going through the truck until I disconnect the battery for about 10 seconds then reconnect. Electrical becomes live again, then when the ignition is turned the electrical cuts out again. I do hear a single cluck at the starter (probably attempting to engage when it cuts out) and a clunk right at the inside fuse box (drivers side).

I have a need for a 12-volt signal to indicate the engine is in start or run mode. I would like to pull this from the engine compartment but I'm not sure what would be the best or easiest way to do this. The 12-volt signal is not used to power anything so it will draw very little current. I have a 94 F150.

I have a 1998 Ford F-150. It has an issue with starting sometimes. The truck won't start with a fully charged battery but when I hook it up to a charger, the truck starts normally. It was going to get the wheels aligned today and when the mechanic went to drive it off the ramp, it wouldn't start. I told him to put a charger on the battery and it started right up. Without the charger it just cranked over and wouldn't start. It doesn't do this every time I go to start it only occasionally. The mechanic had no idea what the problem was and has never heard of this kind of situation. I'm assuming it is an electrical problem but I'm not an expert with engines. The battery was fully charged at the shop and the battery is a year old.

1996 Ford F150 5.0 ... New battery, new alternator, new starter, new coil, dis cap good and rotor is good. New plugs and wires. Ignition mod tested good.
Drove a mile from my house and lost power to my engine. Lights and radio work. Just sits there and cranks and cranks. I'm not getting spark from the coil. Don't know a lot about engines.

My neighbor's kids truck battery drains from full charge to "no start" in 1-2 days. 1999 Ford F-150 w/ 4.6L engine. He has already.....
1) Replaced the Battery.
2) Replaced the GEM module.
3) Replaced the Turn Signal Relay.
He did all this before I looked at it....
I checked the following....
1) Truck off, doors closed, hood open... Amp meter shows 3.6 amp draw. When 1st hooked up, shows 4.2 amps... after a while drops to 3.6.
2) To isolate the draw, we pulled fuses while checking current draw at battery.
a) Under Dash fuse Panel. (Yes, with door closed) We remove fuse #15 "stop lamp switch, speed control, brake shift interlock, ABS, PCM,GEM, RABS test connector". (Really... couldn't be more stuff?)
b)Under the hood is another fuse box (drivers side). We remove Fuse #103. "Junction Block Battery Feed".
3) Found that if we remove the #15 fuse under the dash with the door opens, all interior lights flash on/off at about 1 second intervals... weird.
4) Again, another weird one... with the fuse #15 removed and door closed, the "ABS" indicator and some other indicators and dash lights are staying partially lit... not fully lit.
5) The only "aftermarket" stuff i can see is a dealer installed trailer brake system. Wiring looks professional and disconnecting it does not remove the amperage drain.
I'm hoping that one of you wizards will give me the "slam dunk"... if this happens, it must be that. Can I be so lucky? And, yes. I have my own '06 F-150 that i absolutely love. 6-cyl., manual trans, stripped down without even power door locks... my kinda technology.

I am trying to hook up my power door locks to my command start. I am having trouble getting it to work. Ive tried a number of relay diagrams from the12volt.com. I've tried actuators/reverse polarity and it blows both my factory door lock fuse and the fuse I have supplied to the relays. Ive also tried 5 wire alternating 12 volt positive door locks, and 3 wire positive door lock combinations. Both of these combinations the relays click back and forth fine with the actuators unhooked, when I connect the actuators the doors unlock with the factory switch but when I unlock with my remote it blows the fuse. How to properly connect the actuators?

Looking for a wiring diagram for a F-150 XLT LARIAT 5.8L 4BBL, all the books I have looked at show the wiring for this year with fuel injection and this truck came with a 351W with a Holley 600 4BBL, I have a few wire's in the engine compartment that melted away all the insulation, they are located close to where the harness passes the firewall before the ignition module. Is this a common problem on old models ?. Need a clear copy of the correct diagram for a f-150 1987 with carburetor, how I can get a copy so I can fix this problem before it gets worse.

Here's the breakdown. I have a '95 Ford F150 that I bought the previous year and it has been nothing but a problem. The most recent problem is the attempt to turn on the headlights. I will pull the plunger to turn on the headlights but I will only get the parking lights and when attempting to turn on the high beams I still get nothing. The only way that I get any sort of lighting is if I pull on the turning stick (almost like doing a manual override on a tripped wall plugin). Now here's the kicker. I still have parking lights, brake, tail, cab, and dash lights. Winter in quickly approaching and the nights are already getting dark, pretty soon the days will be just as dark.

I got my first truck today and it's a 1988 Ford F-150 and it runs great! The only issue is that the speedometer doesn't work and I won't be able to register it until it does. I was wondering what I can try out to maybe fix the issue and if not, how I would replace it. Every other gauge works, it's just the speedometer that isn't. The needle doesn't move at all it just sits at a 0 all the time.

I have been trying everything to get my speedo working on my Ford. It didn't work for 3 months after I got it then I decided to put some gear oil on the cable. This made it work for about 200 miles then it would only work with the clutch in and then not at all. I've replaced the speed sensor(not one on rear end the thing the cable goes into), and the gear that goes on the end of it. If I hook a drill up to the cable the tach moves. Could the cable be stretched or just needs some speedo cable lube?

I have a 1999 Ford F150 6 cyl. 4.2, 2 WD with 160,000 miles. Replaced the battery May 2010.
Today battery light came on. Battery gauge did not look like it was discharging. Had battery checked they said it was a little low but OK. Then they continued test and tried to check alternator, test stopped and they said something wrong with alternator most likely.
I took alternator out and had it bench tested. They said it was OK, putting out 98 amp on 95 amp alternator. They said check wires, grounds, harness, connections. Checked connections and wires as much as possible, reinstalled alternator, light still on.
Have not checked fuses yet. Was told to start vehicle, disconnect positive battery cable and if engine continued to run alternator was good, if cut off alternator was bad and to replace. Should I try this and is it true?
What is the part on the fire wall that is between the alternator and the battery that the wire connection runs through? Can it be bench tested/checked?

My center brake light went out a month ago. Thought it was the bulb so replaced that, still didn't work. Checked the fuse and its not broken so my guess was electrical?
Hasn't come on once that I know of but I was randomly walking behind my truck and the light was on. Truck was off lights were off and key wasn't in the ignition.
Went and turned my truck on and turned the lights on and the cbl stayed on. When I switched my lights off it went out and stayed out.
Now I'm definitely thinking wiring but not sure where to start fixing?
Oh and it's a 1990 F150 XLT

After replacing my battery cables (Pos and Ground),My Truck stalls every time I turn on the headlights. The truck stays running with the parking lights on or if no lights on at all. Could I have mixed up the 2 positive accessory wires?

I have an 01' f150 that everything is going out on. I've replaced the GEM module thinking that's what it was to no avail. First thing to go was all four windows which have currently been stuck halfway down for 2 weeks. It's stalling out during idle like it isn't getting enough fuel to it. Brake and engine light on dash are staying on. Radio, interior lights won't come on. Will not come out of park once in. I have to do the old forward, back, middle key trick to get it out of park into neutral so I can start it and go. I've also checked all fuses and relays under dash and under Hood.
