Ford F-150 - 1997-2003 :: Truck Not Moving In Reverse Like Clutch Is Still Disengaged
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.

Just got a 98 f150 yesterday and I noticed last night when I went to shift into reverse, with the clutch all the way to the floor as I tried pulling the shifter back, it sounded like the clutch wasn't engaged at all. Shifting from all the other gears works just fine. Ive found that If the truck is off and I start it in reverse it works just fine.

I have a buddy that has a 1998 f150 4x4 with 4.6l and 332836 km on it. It will go in to reverse but will not go in to drive at all. Is his transmission shot? Or is there anyway to test it to find out what the problem is.
View 4 RepliesFord F-150 - 1997-2003 :: AC Clutch Harness Causing Truck To Not Start
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.
Ford F-150 - 1997-2003 :: Can't Get The Truck Into Gear With Clutch Pushed And It Doesn't Even Grind
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.

E 350 with a 5.8 drive ability headache 94 E 350 with a 5.8. about 1/2 throttle or under quick acceleration it bucks violently and will die if you don't let up on the throttle. This all started when it was run out of fuel. I found the condenser wire was shorted to its own body. Causing the PCM fuse to blow. I have since replaced the condenser. Same problem exists. I have replaced the map sensor with a known good one, same with the O2 sensor.
The TPS is in range and goes through its range smoothly (this was done on my scanner) Also replaced the fuel pump either due to the fuse blowing or running it out of fuel it wasn't working. Fuel pressure is 30 to 32 psi. I've checked the EGR for leaks and proper operation. I have noticed its very hard to start when its cold. Someone has had problems with it in the past as cat is new and i have noticed some things have been removed or replaced recently. The van was just purchased a few weeks ago by my buddy.
Ford F-150 - 1997-2003 :: Engine Only Bucks / Stumbles Intermittently And Not At Idle Or At Harder Acceleration
2001-F150 5.4 Eng. bucking/stumble. I think my problem is slightly different than what I am reading about. Here is what I get (125k miles):
* Engine only bucks/stumbles intermittently and not at idle or at harder acceleration (this bucking is really harsh and makes the truck feel like a learner trying to drive a manual transmission and it is jumping down the street). The engine stumble is not a regular timing such as a cylinder going out and staying out for a period of time. It is quite a random pattern to the jumping
* Originally thought it was humidity related, but now I realize it happens in any climate
* No stumble in neutral at any rpm... only at a stop if I put it in a power brake load.
* When the stumble shows up, it seems like the throttle is around 10-25% (my best guess)
* Sometimes goes days without issue, but sometimes every ride and virtually every acceleration.
* Normally no stumbling at highway speeds, unless going up a hill.
* Every time it stumbles, it can be eliminated by either backing off on the accelerator some, or hitting the accelerator harder.
* No engine codes or CEL has ever come on
* Fuel mileage appears to be the same before and after the trouble started
Here is what I have done to try to correct it:
-> Fuel related (bad gas)... tried to run the tank as close to empty and fill it with fuel from different stations... when this didn't work, I have added HEET to it to dry up any water in tank.
-> Fuel delivery... replaced the fuel filter... seemed to work for one day, but then the gremlins came back.
-> Fuel delivery... ran multiple injector cleaners through tanks of gas.
-> Intake... replaced the filter.
-> Electrical... I don't believe this is related, but my battery died... parts store tested the system and stated the alternator was bad... replaced it, and took the old one to the parts store for bench testing and it was 100% OK... even thought the old showed OK, I left in the new one as a precaution. Only other item was a set of plug changes around 30k miles ago... I think I put in the super duper Bosch plugs with a lifetime warranty.
Current thinking and items I don't understand:
A) The bucking is so severe, it appears to be a random harsh loss of either fuel or ignition. A component that has failed electrically should give me a fault code with this level of severity. No trouble codes or indicators to electrically sense this disturbance...
B) For the fuel path, the most likely item is bad gas and I emptied my tank by running it as close to empty as possible and then used different gas and HEET to eliminate water. THIS MIGHT STILL BE THE CAUSE???
C) Another one for the fuel path is an intermittent fuel pump electrical connection or a weak pump from a pressure point. But if this is the cause, then why does it dissappear upon harder acceleration?
D) One last fuel thought is injectors... perhaps one or more have a range of delivery that they don't work properly... but this doesn't make much sense as at idle and harder accels are fine
E) From an ignition standpoint, perhaps I have failing COP's. I have not just gone out an replaced them due to my limited budget and the difficulty I read about changing them. Again, if one of these is failing in an either open or short condition, the computer should set a code for a misfire for the related cylinders. I get nothing. Hence my hesitation in making this change so far.
One thing i don't understand from the various posts is that the cops can fail under loading. what makes this happen as electrically, i don't think they can detect a load or not? it is hard for me to also understand why my truck would allow me to back off on the throttle or hit it harder and the issue disappears.
Subaru - Legacy :: 2003 - Replaced Clutch Now Reverse Light Going Out - Clutch Not Smooth?
I had the car worked on a while back. They replaced the clutch and the viscous coupling in the transmission. ('03 Subaru Legacy manual transmission) Things seemed fine, then I realized my reverse light was acting like it was going out. Fuses are fine. A while later the car decided the clutch didn't need to respond as smoothly. Then: "Nope, you're funny to think you can drive me. I'm not budging." The car started grinding gears. I have to slam it into gear for it to work so I can drive it home and let it sit. The car will go into gear when off, no problem. New fluid has been put in. Bled. Then some sort of SUPER LUBE was put in and it still grinds. What might be happening? I really don't have the fundage in order to buy a new car at this time. But at the same time I hate feeling like I'm chasing a rabbit down a hole..

Ford Super Duty (1999-2016) :: Codes P0172 And P0174 / Truck Bucks And Coughs / Zero Power When Driving
I have a 2008 Canadian F250 SD 5.4 triton. Its got 224000km on it and began to get the dreaded 5.4 dieseling when hot and idling. I replaced the timing chains, guides, both tensioners and crank gear. I confirmed the cam timing was correct with the crank key at 6:00 and the chains marks on the R and L. I replaced 2 coils on cyl's 2 and 3. I replaced the MAF sensor, fuel rail pressure sensor, cleaned and confirmed working the crank sensor and both cam sensors. I fixed the broken Bank 2 cam sensor wires. I changed the plugs and replaced all 4 O2 sensors.
Now the truck idles great but when driving it bucks and coughs and has zero power. I cant even get to 80km/hr. The computer now shows codes P0172 and P0174 which means the Bank 1 is rich and the bank 2 is lean. The O2 sensors are working and moving around. The back 02 sensors are both reading in the 0.8Volt range but bouncing around. The front 02 sensors are both moving from 0.1 to 0.8 constantly. The long term fuel trims are +9.5% bank 2 and -4.7% bank 1 at idle. When the throttle is off idle they become +25% bank 2 and -25% bank 1 . How is this possible and what can I do to fix this engine?.
Toyota - Tacoma :: 2001 Bucks / Jumps Like Clutch Is Alternately And Rapidly Grabbing And Releasing
My 2001 Tacoma drives well most of the time, but when in 4 wheel drive low range, low gear, in demanding circumstances like heavy snow, it will buck, jump, act like the clutch is alternately and rapidly grabbing and releasing (but I'm pretty sure it's not actually that). Tires are good. Four cylinder, standard transmission.
View 7 RepliesFord - Explorer :: 2003 - Loud Clunk When Put The Truck In Reverse And Once Hit The Gas
I am trying to track down where exactly a clunk is coming from on a 2003 Explorer 4x4(auto, hi, low). My buddy brought it by my house yesterday and i cannot pin point it. If you put the truck in reverse, once you hit the gas, it clunks pretty loud. If you just put it in reverse, let off the brake, it will not do it until you hit the gas.
I got the explorer up in the air and crawled under it. I had my buddy switch from forward to reverse, and back again. Every time he let off the brake in forward or reverse, it would clunk. The reverse clunk was definitely louder.
It does the clunks in all settings, -auto,hi,low. No flashing dash lights. The dash lights do come on accordingly. One thing he pointed out was the Auto,HI,Low Buttons themselves are not backlit anymore. Not sure if that has anything to do with it?
I cannot narrow it down as the whole transfer case, front driveshaft and front diff, shake with the clunk. U joints don't seem to have play (prying with small prybar). I then went ahead and unplugged the big wire connector at the transfer case and the clunk went away.
Ford 7.3L Power Stroke (1999-2003) :: Truck Stalling When Going Into Reverse
This just started happening last week. When I put the truck into reverse, the engine lugs down and dies. It' as if the AT is fully engaging reverse gear with no clutching action. If give the truck a bit of pedal, I can put her in reverse and back up without issue. Going forward into Drive has no issues.

I have an 03 Escape that is very difficult to start after it rains, if I open the hood and let it dry out for a few days it starts fine, however if I put it in drive or reverse and press the gas it will not move... if I hold the brake while it is in gear and give it gas it does not rev up, however if I put it back in neutral or park it revs up. I normally cover the hood with a tarp to prevent this from happening however I was shutting the tarp in the door and a lot of water got in the floor board of the truck I sucked it all out, that night the radio started playing all on its own, I came out to the truck turned the radio off it stop went back in came back a while later and it was on again, so I pulled the fuse... but there are two buttons that stay lit on the radio the preset button 1 and 2 stay on all the time and I can not figure it out either. This is my beach truck I only use it for that purpose..however it is fall fishing time and I really want to go...

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.

My AC clutch is not turning on. I do not have any AC gauges but if I unplug the compressor and put a meter on the 2 harness pins, I do not see any voltage when truck is running and AC on. I really don't know much about AC but I am thinking the problem may possibly be the low pressure switch or possibly low on freon. How can I check if I am low on freon without gauges? Where exactly is the low pressure switch located on my truck and if I jump the switch and the clutch kicks on, does that tell me that the problem can only be the low pressure switch or low on freon. I'm just trying to work through a few of the gremlins.
