Ford 7.3L Power Stroke (1999-2003) :: Truck Stutters On Road After Long Drive When Running

This is wife typing in middle of trip. Today we drove almost 300 miles down the road before it stuttered. We lost the tach but nothing else. No check engine lights. It has done it a few times since. Watching with Torque and don't see anything there. Have 100 miles to go and it's happening more frequently. Replaced CPS 4 weeks ago with a Ford grey. Running down road it's 95 day. Oil was checked to be good at 211, transmission 182, EGT 790, pulling enclosed 6x12 cargo trailer. What can I check?

Ford F-150 - 1997-2003 :: Truck Randomly Not Want To Start While In Park

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.

Ford F-150 - 1997-2003 :: Truck Randomly Started Missing - Misfire On Both Cylinder 1 And 8

I've got a 97 f150 4.6 that has randomly started missing over the last month. It has started to get more frequent and codes are showing a misfire on both cylinder 1 and 8. Both of these cylinders run off the same coil pack. I'm thinking its the coil? The plugs and wires, motocraft, have about 3k on them and the truck runs great otherwise. I just don't know how common a coil would cause this or if they would act intermittent like this.

Ford F-150 - 1997-2003 :: 2002 4.6L Dies While Driving Randomly

My 02 F150 4.6 4x2 shuts off while driving - usually when I am coasting, but also at varied speeds, even highway speeds. The motor dies, the gauges all go to 0, and the odometer shows ------ I have to shift to N and coast...if I try to re-start it just turns over and over...gauges still all at 0.

I have determined that if I reach behind the fuse panel and wiggle the wiring harness, my gauges will come back and I will be able to re-start it.

I noticed yesterday, that after it did this and I got it re-started, the red 'Theft' light was blinking rapidly. A clue, perhaps?

I have tightened the 10mm bolt that holds the two wire bundles into the back of the cabin fuse box (by driver's door).

Where to start? I have crawled under the dash, looking for loose, chaffed or otherwise odd looking wire, but so far no good.

Ford Super Duty (1999-2016) :: 2008 F250 5.4L - Gauges Will Randomly Start Jumping Around Then Truck Will Just Shut Off While Driving

So I'll be driving down the road and the gauges will randomly start jumping around then the truck will just shut off, this just started a couple days ago, it seems to be gaining in frequency, when i try and restart the engine all my warning lights flash on and nothing happens, try again and it starts back up, now the last time it happened all of the above happened but it was followed by a fast clicking noise from under the steering column, it has to be a electrical issue as i have full tanks and motor is in tip top shape. Also no codes pop up with my code reader.

Ford 7.3L Power Stroke (1999-2003) :: Truck Shuts Off When Going Down Highway

Headed to town with the kids and my truck shuts off going down highway. I pull over and start it back up and make it to 30mph and shuts off again. This time it will not start. I have 1/4 tank of fuel, I first thought it maybe the issue inside the tank causing it to shut off. I get some diesel pour it in and it fires up for about 15 secs and shuts off. I pull the fuel filter, making sure o have fuel in the bowl. Start it up and it runs for about 10 sec. I then swap out the CPS. Same thing, runs about 20 and cuts off. I then call AAA because I am tired and ready to go home. I have it towed to my buddy's shop. He has not looked at it yet.

Chevrolet :: 1999 Truck Won't Restart After Driving At Highway Speeds For More Than 20 Minutes

I have a '99 Chevy 2500 diesel truck. After driving it at highway speeds for more than 20 minutes and turning it off, it won't restart. The problem seems to be in the battery cable and is definitely heat-related. In cold weather or after a fairly short drive, all it takes is popping the hood to cool off the engine compartment, and waiting. If the engine and/or the weather is too hot, that can take an hour. Then it starts just fine. I've cleaned the terminals and made sure the connections are tight. Two mechanics have looked at it and were stumped.

Ford 7.3L Power Stroke (1999-2003) :: Truck Has Begun Randomly Having A Delayed Start

As would be expected things deteriorate on a 16-year-old truck. My alarm has, on a few occasions, decided to annoy anyone around by activating for no apparent reason. This has happened in various conditions (in the parking lot, in the driveway, right after I've driven it, or sitting half the night). I chalked it up to aging circuitry.

Now I've picked up something new. Over the last few weeks my truck may or may not arm. It seems to be a flip of the coin. I'll drive to the store and I push the button on my remote and the truck goes "beep"..."beep". 10 minutes later I drive home, park the truck, push the remote, and the truck goes "beep"...and that's it. My alarm light is blinking two quick flashes when this happens.

Since this has started my truck has begun randomly having a delayed start. I'll disarm the truck, turn the key, and nothing happens for about 1 second or so (seems longer) then the truck starts normally.

Both of these issues started pretty close to the same time. I would normally go straight for a starter issue but I don't know if these might be related. I'm the second owner so have absolutely no idea about the Ford anti-theft system, how it's connected, or what the blinking lights mean.

I'm considering disconnecting the anti-theft system to see if that makes a difference but, as stated, how it's connected, what I might disable, or how it works. Was there any documentation published on it?

Ford Super Duty (1999-2016) :: 2003 - Hesitation / Truck Shutting Off Randomly

I have a 03 F250 5.4 4x4 auto, last year I had a problem with the truck shutting off randomly. So after doing all the dumb stuff and research I ended up concluding that the FP relay was acting up and my understanding is that, it is located in the fuse block. So not wanting to replace it I wired up my own relay next to the safety switch in the passenger side kick panel and it has been fine ever since. I did put a new pump in it (Cali emissions) Now to present day-

Over the past month my truck would have a slight hesitation problem when accelerating on the highway/up grade. The issue was it would go away for a while when you would shut the truck off and be good for a while. Well then it started happening all the time.

I knew I was do for a tune up (215,000) so I did all the plugs, COP's, fuel filter and a PM. It got a lot better but was still there at the top end. So after doing a lot of research I found a lot of people having the same issues, so for testing purposes I cut the CAT out and installed a section of flex pipe. (Iwill be installing the cat back in)

So last night I take it out and its even worse...I went don to my buddy's place and hooked up a Versus and got no codes at all, no misfires on the counter..absolutely nothing. So I did what I should have done in the beginning and duct taped a fuel pressure gauge to the windshield and took off.

At idle I have 30 or so PSI, and when it was fine it would stay around that, when it started acting up it would drop to 5-2psi under load and go back to 30 or so PSI at idle. The other thing is now I only have 1/4 tank of gas.

What I am concluding is that the pump is getting hot and weak, because when I had a full fuel tank it was better and now I have less fuel to cool the pump and it is happening faster. Should I just throw another new pump in it? Or go after a voltage problem to the pump?

Ford 7.3L Power Stroke (1999-2003) :: Truck Misses And Randomly Dies Only When It Rains

I am at a loss on what this could be. For the past 8 - 9 months my truck will randomly miss and if I am going slow enough it will cause the engine to quit but only when it is raining. I sometimes get a service light when it happens but as soon as i turn the key off and back on it goes away. My truck runs perfect otherwise and even when it rains except when it randomly does what I just explained.

This started when I replaced my passenger side valve cover gasket and I also took out my "brain box" (don't remember what it's called) and put it back in (didn't replace it). I did have the up-pipe replaced as well around the same time and put in EGT, boost and trans temp gauges. That's about the only things engine compartment wise that's been done.

I did just take it to a shop to put on a scanner and after his testing it did spit out 1 code. It was the cam position sensor. Can this sensor cause what I have explained? Like I said, this only happens when it rains. Doesn't matter if it's poring or barely sprinkling.

Ford F-150 - 1997-2003 :: 2002 - Transmission Stutters While Going Into OD?

I have a 2002 f150 2wd 4.2l engine. With 135,000 miles I just replaced the battery about 300 miles ago and I usually tow a trailer almost always. Also I replaced the Plugs and Plug wires about 15,000 miles ago When I am towing I turn the OD off. Now the problem. I noticed that when I am not towing now that when approaching highway speeds it seems to shift back and forth from overdrive while accelerating only.

But when pulling a trailer with OD off it shifts fine. No engine codes appear. I am due to service the transmission fluid I think I have about 35,000 on the fluid now but before I do I just want to pass this that while I have the pan out. Is there anything else I should check or could this just be a issue with dirty fluid Or Possibly the drivetrain controller because I hardly ever drive without towing..

Ford F-150 - 1997-2003 :: Stalls / Stutters - Cranks But Won't Start

So I leave town Friday with the wife's car for a golf tournament that is 4 hours away. I left her with my 2001 F150 Supercrew Lariat 4x4 5.4L. She calls as I am starting my practice round on Friday stating that the truck had died on her in the local Dillons parking lot. She had driven to the east side of Wichita, then drove all the way back to the west side before swinging into Dillons to get some chinese food for lunch. When she gets in the truck to leave, she starts it and it runs rough.

She gave it gas and it ran fine for a few seconds, she put it in drive, and then it started running rough again. She stopped the truck in the parking stall ahead of her, turned it off, and restarted it. Same thing...runs rough. She tried giving it gas, but it would not go above 1500 rpm. Then it just died on her. She then tried cranking it, but it would not turn over. She let it sit overnight and got a ride from a friend (it was 102 degrees out), went back the next morning to try again. Same thing, just cranks. So I get back last night and go up with my scanner. No codes, no SES/CEL.

So, I am now thinking it is the fuel pump. I crawled underneath the truck and had her turn the key so I could see if I can hear the fuel pump. Nothing. I went ahead and disconnected the battery to let it sit overnight.

I am about to head up there and see what I can do. So far, here is my list of things I need to check:

1. Fuel pump relay #301
2. Fuel pump fuse #18
3. Check for the theft light
4. Check "inertia switch" on the passenger side kick panel
5. OPEN gas cap and listen for the fuel pump (had never heard of that one)
6. Hit the gas tank a few times with a rubber mallet to "jar" the fuel pump (again, never heard of that one).

My question to all of you is: Am I missing anything else? Alos, with it running perfect, then running rough and suddenly dying, would is necessarily be the fuel pump? I had read something about a "Fuel Pump Module" located near the spare tire. Is that something I should check into with it running rough (well, not running at all now) like this?

Ford F-150 - 1997-2003 :: 2002 Truck Shut Off On Interstate When Driving At 65 MPH

Truck in question is 2002 F150 4.6 with 150K miles. Crew was on interstate tonight driving 65 MPH and truck shut off. They called me out to trouble shoot. Engine had oil (was a quart low) and will not start. Starter engages but will not turn motor over. Had truck towed back to my shop. I removed belt just to see if it may be a locked up pulley i know, long shot)... it was not.

Employed called a shade tree mechanic he knows and trusts. He said was likely a broken timing chain and that is a common problem in 4.6. Said locked engine is probably because broken chain is wrapped around shaft. When I turn key fan does move about 1/4 inch.

1) Does this sound like a possibility or even a plausible explanation? Just trying to verify the information.
2) If this is the case, would a repair be advisable, or is engine likely shot and i should just replace it?

Ford Ranger / B-Series :: 1997 - Randomly Jerks On Highway?

I got a 1997 Ford Ranger 2.5L that randomly jerks on the highway and I can't figure out what the problem is. This morning I had a 3 hour drive and it was fine on the first hour and then the last 2 hours it will randomly jerk on the highway and then be find for a little bit and then do it again. I don't know what the issue is? I did scan my car this morning and did have two code P0141 and P0113 not sure if these would have anything to do with it or not. Also my speedometer is hit or miss when it works, other than that everything else is fine on the car no check engine light or anything like that.

Ford 7.3L Power Stroke (1999-2003) :: Lost Fuel Pressure Going Down The Highway And Truck Died

Last night when i left work I noticed my fuel pressure was running about 77 psi, it normally runs about 68psi. today I took my daughter to practice and it was around 83psi, on the way home it was up to 95psi, so I parked it and took another truck to work.

About a week and a half ago I lost fuel pressure going down the highway and the truck died, finally decided my pick-up foot must have come off and had my sister in law bring me some diesel and it has drove fine ever since. (it was right at a quarter tank).

I have the FRX from riffraff and am thinking some pieces of that foot have got into the fuel bowl and plugging up the return. Things to check? Could it be a problem with the fuel gauge or wiring, and how to test them. It is an autometer gauge from riffraff.

It will probably be a few weeks before I can do much more than clean out the fuel bowl. I don't have anywhere inside to work on it and it's been rain/sleet/freezing rain/snow for the last 10 days. I have most of the stuff to do the hutch mod and its next on the list but was hoping to put it off till spring.

Ford F-150 - 1997-2003 :: 1999 - Headlights Just Randomly Quit

I have a 99 F150, with the 4.6, and my headlights just randomly quit. I checked all the fuses, and switched the MFS, and main headlight switch. All I have is my DRL's. I also checked for wires coming out of the plug-in on the column, but they seem good too. I'm just not sure where to go from here....
