Ford F-150 - 1997-2003 :: AC Clutch Harness Causing Truck To Not Start
Jun 5, 2013
My issue started as simply a lack of air conditioning. Upon initial inspection I noticed that the compressor clutch is not engaging when I turn the ac on. So I figured the next step would be to see if I am getting voltage to the clutch. My Chilton book says to test this with the truck on, so I disconnected the harness from the compressor, attached my meter to the cable, and attempted to start my truck. I've found that the truck wont start with this cable disconnected. It will turn over but just never starts. Also the fuel pump comes on as it should.
I've repeated this several times. It always starts with no problem when the compressor clutch is connected. I understand that there is some monitoring circuit with the pcm so maybe that has something to do with it but I'm pretty fuzzy on how that works. Upon further inspection, it looks like I should be able to test my ac signal with the engine off, so maybe that's not such a big deal, but this whole truck not starting business is blowing my mind.

After/during the rain, every other time my truck loses considerable power to accelerate. It's not consistent but happens increasingly often. As I accelerate up to ~ 50km/h (also when I reverse), my engine will shake the entire truck. Past 50 it "appears" to go away. Typically this will last up to 10 mins and will disappear and run fine again. The last time it happened the check engine light came on and went away the next day. After reading online, I've heard about the "COP" connection??

My truck was working fine and I drove it to school one day and I was driving and I noticed the RPM was high and the truck wasn't moving correctly luckily I made it home and parked it now it won't move at all I can shift into gears and I put it in first and reverse and let off the clutch and it doesn't move like the clutch is still disengaged. The Slave Cylinder is pressing against the pressure plate to disengage the clutch and then releasing. I have a single cab 1999 Ford F150 4.2 V6.

I'm having an issue with my truck. It only seems to happen during warm 80+ weather. In the mornings, and during colder weather, the truck runs perfectly.
My problem is; Every time I go to get going and feather the clutch, either in 1st or reverse, my truck bucks wildly.
I changed the plug wires about 500 miles ago, and am about 4000 miles on a rebuilt engine (plugs as well) and new clutch/resurfaced flywheel. The clutch reservoir is full and I haven't noticed any leaks. There have been no codes thrown.
Could it be a possible fuel problem? I think I changed the fuel filter about 7k-10k miles ago.
I was also wondering if the Gotts mod could be causing it. I did the mod during the winter time, and this is my first summer with it on. My air filter is fine.

Well here it is I just put a new slave cylinder in my 02' F-150 and once we figured out all the little issues we were having we finally got the truck to fire up!!! Now my problem is that when the truck is running I can't get the truck into gear with the clutch pushed and it doesn't even grind. But when the truck is off it goes through the gears no problem what so ever. When we did the slave cylinder while we were in there we just replaced everything clutch, pressure plate, flywheel, rear seal, and pilot bearing. We figured that since all the shops were quoting me 800 and up for just doing the slave that since were in there we might as well do everything since nothing has ever been replaced yet. My question is why will the truck not let me shift into gears when running but no problem when off. Oh and yes the system was bled after doing the slave actually twice so far.

I've tried everything I can think of to get my cruise control working again to no avail. I have a late 99 with a 6 speed. So far I have checked all the fuses with a multimeter, I've checked continuity from the harness under the dash through the clockspring to the switches, truck does not start without the clutch pushed in so the neutral safety switch works, has the upgraded switch and harness off the master cylinder. the previous owner said the cruise was intermittent about a year after they did the harness and switch recall on it. is there a way to test the harness and switch? I got a 1800 mile round trip coming up in about a week and I am gonna have a sore foot if I cant figure this out.

2002 Model, F150, 4.6L Triton....
Early last week one day my truck just wouldn't start. I had driven it the day before. but that day nothing. It would spin over just not start. the following day though, it started as always, no hesitation and run smooth. But the was the last day it has ran.
Since then I have checked the relays and fuses. I have checked the inertia switch (pass. side kick panel). Removed the cap on the schrader valve on the fuel rail. (no pressure)
I have sprayed starting fluid into the throttle body and it starts for 1 to 2 seconds. (dies once starting fluid is gone). I have changed the fuel filter and pulled the bed and changed out the fuel pump. I'm thinking about trying the fuel pressure regulator next.
Just not real sure where else to go if that doesn't work.....

Took the beast out for a good road trip to try out the new tires. She is running good now, but has picked up a weird miss which cause the truck to shudder. It does feel and sound just like a miss, I know that it is a diesel but that is only way to describe it.
When driving along with the cruise set at 75, when I hit a hill, the truck will gradually accelerate, and it will miss a beat. Just like you turned it off and right back on very fast. Usually once, twice if the hill is long. If I accelerate harder it will not do it. Most often does it while gradually moving accelerator.
Has new fuel filter ad cam sensor.. Runs great the rest of the time.

First of it's a 2003 with the 4.6. I replaced a bad alternator a couple months ago and all was fine. On the way home today the radio volume went quiet and all the dash gauges were dead. Truck died and wouldn't even try to start, no starter clicking or anything. A couple times the gauges did the "sweep" but still no start, not even a starter click. Barely even operated the hazard lights. Towed it home and hooked up the jumper cables to my 7.3 Excursion. Truck started right up and I left if hooked up for a couple minutes hoping to get enough charge in the battery to get it in the garage.
Unhooked the jumper cables, got in the truck and noticed the voltage gauge was reading nothing, tried to move it and it died. Hooked the jumper cables back up and let the Excursion charge it for about 5 minutes. Started, drove it to the garage (100ft) and backed it in. Noticed the voltage gauge was where it should be. Turned it off and back to run (didn't start) and the voltage gauge was reading good and it started right up.
Now, it doesn't appear that the battery or alternator is bad. Is there something else I should be looking at? I can take the alternator off and have it checked but don't want to go through the work if not needed to chase a ghost. Advance auto Tough One alternator BTW.

I have a 2000 F150 XLT 5.4L truck. I noticed the AC went out about a month ago and since then I could hear the AC/Clutch bearing making noise. Well I went to start it the other day after eating dinner out and it wouldn't start. It sounds like it wants to start but it just doesn't have enough umph. I replaced the starter and charged the battery up to 100 percent. It still won't start.
If I take the belt off it will start and I checked the AC/Clutch and I can move it with my bear hands. I tried disconnecting the AC/Clutch fuse and relay but that didn't work. Is it possible that the Clutch is freezing up when I try to start it?

I have a 2001 ford F150 with a 5.4 2WD, with a starting problem. Last Friday I went to leave work the truck cranked but did not start, turned the key off and tried again same thing, on the third try it started. Drove it home 30 miles with one stop on the way, restarted just fine. At home in the driveway I restarted it 5 times without a problem so I was thinking it was just a glitch. Did not drive the truck all weekend thinking the problem was fixed.
Monday morning leave for work and everything was fine, went to start the truck in the afternoon and the same problem as listed above (3 or 4 tries and it started). It home again in the driveway restarts every time. I do not have any check engine light on but I thought I would still plug in my code reader NO CODE. Where to start troubling shooting this problem?

2001 f150 4x4 5.4 205k ... This truck is not my daily driver but I use it about once or twice a week. Last night I drove it to the store and it ran great. As good as ever.
This morning it won't start. It cranks and the battery is strong but no bang. It was cold. Just below freezing for the first time this year. No blown fuses where would you start?

I have a 97 f150 with a 4.9..... I drove it less than a half a mile and shut it off. when I got back in it to start it up it wouldn't do anything like the battery was dead but all the electrical worked but it would not turn over. after about 4 hours when I returned, it started just fine. drove it straight home and shut it off and immediately tried to start it again and had the same issue. What the culprit may be ?

Last two weeks I have had my truck randomly not want to start while in park. If I shift to neutral it has so far started up everytime, but as of today I was at work at a security gate that sits at the bottom of a mild to moderate incline and the moment after I had put the truck in park and lift off of the brakes the truck clicks moves forward making a clicking sound life the parking prawl is not fully engaging or something.
So doing some google searching the closest answer come up with is that its a failing/out of adjustment Transmission Range Sensor. Does this sound right? I had the tranny rebuilt last year and only have put on 7,500 to 10,000 miles so its not a matter of age since it looks like the sensor was replaced at that time.

I did the power door fix, wrapping the door actuator motor 'resistor' in foil, and all was good. This morning I started the truck to move it, all fine, then pulled the door panel off to readjust the window guide in the door as windows were binding. After adjustment I went to turn on the ignition to test the window and the Theft light is on, and the truck won't start! It's a1999 F150, 5.4L.
1. The power comes on when I turn the key to ON, then when I turn the key to start the truck I hear nothing, no clicking, and the power goes off.
2. After leaving the key in the On position for 45 seconds, the Theft light blinks rapidly, the odometer is all dashes, the RPM and Speedometer gauges swing to max, then back to 0.
3. When turning the key to start the truck, there's a 1 click sound (solenoid?), then all power goes off on the instrument panel, no cranking.
What might have gone wrong here? Could the wrapping of the 'resistor' in foil in the door actuator have caused an electrical short? [URL] .....
Below happened previously but not any more...
4. When I turn the power back on to ON and push the buttons for the windows, the power seems to cycle On / Off in 2 second intervals, as the window goes down a bit, then stops, then goes down a bit, stops etc. and the lights on the instrument panel dim / go on / dim in the same cycle.

I ran out of CNG - truck won't start on reg fuel. Fuse good, relay clicking and I believe I have voltage going to plug connector going to tank. However, I do not have any wiring diagram to know what I'm looking for. The plug is four wire - yellow- 11 volts, red / black stripe 7 volts, black / red stripe and black wire no volts. What checks can I make before dropping the fuel tank and pulling fuel pump? 2003 F150 7700 Bi-fuel ....
