Ford 7.3L Power Stroke (1999-2003) :: Service Engine Soon Light Comes On For A Couple Minutes At Cold Start

On my 7.3 super cab, I changed the fuel filter last Friday and now on cold start the service engine soon light comes on for a couple minutes (approximately) on a cold start. No other issues. Tried scanning with my scan gauge 2 and no codes. (of coarse I think that thing is a joke for scanning). Not sure if this means anything, but last week before I changed the filter I thought I smelled diesel fuel on a couple different occasions. If I actually did it may not even be related.

Ford 7.3L Power Stroke (1999-2003) :: No Start After Starter Replaced - Engine Won't Fire

I replaced my starter with a new one from car quest yesterday, it was starting to turn the engine over slow. I checked the batteries, they were fine, so went for a new starter. After installing, the new starter turned fast and fine, started the truck ok, but I noticed a fast clicking sound from under the dash. Ran it home and tried to start it up this morning, turns over fast, the clicking sound is still coming from under the dash, but the engine won't fire. Just turns over. When it's turning over the check engine (and all the other dash) lights flash.

Ford 6.0L Power Stroke Diesel :: Truck Will Sometimes Momentarily Cut Out And Buck A Couple Of Times

I replaced the speed sensor in the differential yesterday, but it didn't make a lick of difference. I've been having intermittent problems with the speedo ever since I bought the truck. When the speedo starts acting up, the truck will sometimes momentarily cut out and buck a couple of times. It was first mentioned this post, post # 35. I had the truck in the shop for a new oil cooler, EGR delete, standpipes, dummy plugs and STC fittings, and when I got it back it ran worse than before as detailed here in post #1. It turned out I had a torn IPR screen.

I replaced that and it cleared up all of the problems I had except for the speedo problem I originally had. The truck actually ran perfectly on the way home from work yesterday, about 20 miles. No speedo problems and no cutting out. This is not unusual, as the problem is only intermittent. I put the new VSS in last night but did not drive it until this morning. This morning, same thing again, speedo swinging crazily. When cruising about 70 it the speedo would suddenly jump up to about 90 and that is when the truck would cut out and buck a couple of time. The VSS is a Dorman product and proudly displays "MADE IN CHINA".

Should I try a better quality sensor? Rock Auto sells an Airtex/Wells sensor that seems to be of good quality, but I can't determine where it was manufactured. The only reason I bought the Dorman is because I could get it next day from Amazon. Should I be looking at another source for the problem? This is very discouraging because this one thing is what is keeping the truck from being mechanically sound, and I'm trying to get it ready to tow an RV this summer.

Ford 7.3L Power Stroke (1999-2003) :: Engine Died Suddenly / Turns Over But Won't Fire

I have a 99 F450 bucket truck. I was up in the bucket when the engine died suddenly. It turns over but won't fire. I have no dash warning lights now either but everything else seems to be working. Lights, radio, annoying beeping sound from the key left in the ignition, etc. There are roughly 5 or 6 fuses in the panel to the lower left of the steering column that don't have power to them. Are they all supposed to have power when the ignition is on? I checked the fuse panel under the hood and all of the fuses that have 12V to them are good. There are a few small ones that don't have power to them but I don't think they do all the time.

Ford 7.3L Power Stroke (1999-2003) :: Run Extremely Rough For A Couple Seconds Then Died?

Tried starting the truck, fired ran good for a couple seconds, then ran extremely rough for a couple seconds then died.

I did some research and changed the ICP because there was oil in the connector so even if it wasnt causing my issue i wanted to replace it.

Now I have the same issue but it will actually run a little longer and not stall. I thought it was fixed so i took it for a drive, after about 3 miles it bogged down and i was able to make it home with half throttle going about 30mph. Sounds almost like its running on half the cylinders. i unplugged the ICP and it continued to run that way.

I had done the 50cent mod a few years back with the peices from ford but i know the harnesses themselves can wear through so i checked the resistance between the center pin and the two pins to the right and left for both the injector harness and they had about 3ohms.

I am leaning towards an IPR but from the reading i have done it seams like most trucks will not restart after they die. I have AE so i am going to hook it up later today, just wanted some reccomendations on what to look at.

I also remember when i shut it off the unplug the ICP to see if it would clear up the needles on the gauges did a full sweep as if i disconnected the battery which i though was weird.

Ford 7.3L Power Stroke (1999-2003) :: A/C Goes To Defrost At First When Cranking But Then Runs Fine After A Couple Seconds

I have Warn hubs that I have to lock in. All works good. A/C goes to defrost at first when cranking but then runs fine after a couple seconds. So, I was thinking that maybe my pump is running all the time. Who knows. I'm sure all my vacuum lines are dry rotted. What exactly is the need for it exactly and what's the best way to cap? Hoping to do it at the unit itself if possible.

Ford 7.3L Power Stroke (1999-2003) :: Started Up After Cranking A Couple Of Seconds / Blowing Oil Out - Valve Cover?

I had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.

When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Battery Drain And Slow Crank If Sitting For Couple Of Days?

If I leave my truck sit for a couple of days, the batteries are noticeably weaker. It's fine overnight, but two nights and it's slow to crank. Three and it won't start without charging the batteries. I checked for a drain last night and found that it was drawing 1.2 amps.

That seems like a lot, no?

Ford Super Duty (1999-2016) :: Check Engine Light Turns On Randomly And Goes Off After A Couple Of Seconds

I own a 2000 Ford F-250 5.4 Automatic. It tows my 5th wheel trailer very good. On our last trip it suddenly experienced the "check engine light" effect.

The light turns on randomly and either goes of after a couple of seconds or it doesn't go on when I restart the engine.It is mainly annoying, but when in towing it really hurts, because the engine switches into an emergency mode and stalls.

I read that the engine uses only 4 cylinders. I read many articles on the web about that light, but I couldn't find a solution. The thing is I brought the car to several repair shops but none read a code from the computer.

I think it's not a real fault but a misreading or maybe a cable that's grounding? The problem is, I can't bring the car to a repair shop, because there is nothing wrong with the car. How can I find the source of the problem?

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss And Almost Shut Down At Random Times

I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.

Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?

Ford 7.3L Power Stroke (1999-2003) :: Fuse To The Starter Keeps Blowing

I had a problem with this issue a few months ago, was 45 minutes away from home, blew the fuse to the starter. Switched another one in, blew it too. Had it towed to a shop, they did some diagnostics, felt like it was a short in the starter, replaced it and all has been well (as far as that particular issue) until this morning. Got in it, turned the key it cranked for less than a second and stopped. I pull the fuse, sure enough, blown. Swap it with another, it blows.

I know I have a bare wire in the column, the OD light wire is chaffed, I fixed it before but it must be worn again because I can get it to light up depending on positioning of the shifter lever and as I recall, every time the fuse blows the steering wheel is cranked to the left.

Ford 7.3L Power Stroke (1999-2003) :: Gallon Of Oil Coming Down Around The Starter

I just reinstalled my turbo and started the truck up to test it. After 15 seconds or so it shut down so I hopped out to take a look. I had about a gallon of oil coming down around the starter. All I did was reinstall the turbo (I had previously installed without the rear pipe hooked up). I can't see where the leak is coming from but this thing is not even remotely drive-able. My best guess is the pedestal somewhere?

Ford 7.3L Power Stroke (1999-2003) :: Low On Coolant / Oil Droplets On The Starter

Edit, I have also noticed I have been getting low on coolant, but without any noticeable coolant leaks. My engine oil still looks clean, where could the oil be going? How do I fix it?

2003 Excursion 153,000 miles - stock injectors, gt38r with new pedestal, Adrenaline HPOP, double transmission cooler.

I've noticed after some heavy towing with my camper (8,300 lbs), I've been getting a new oil leak showing up on my garage floor. I crawled underneath this afternoon and found three large oil droplets on the starter. See picture. What could this be dripping from?

Ford 7.3L Power Stroke (1999-2003) :: Brakes Sometimes Soft Other Times Firm

So the other day I had someone change lanes and slam on the binders right in front of me which caused me to slam on mine. Luckily no one got hit. Now my brakes feel different. Sometimes the pedal feels nice a firm other times it pushes in 2-3" before starting to brake. The fluid level has not changed in the resevoir and the hydroboost appears to be working fine. The power steering is still operating as before. I have checked the calipers and none are leaking.

My suspect is the master cylinder but was wondering if the symptoms are common with the master cylinder failing? I'm thinking internal o-ring has failed due to the near accident event. I'm going to do power steering flush just because I never have. Is there anything that would display these symptoms that I could check before buying the master cylinder?

Ford 7.3L Power Stroke (1999-2003) :: Starter Sometimes Spins Free 2 - 3 Tries Before Engaging

I just bought a 99 F350 to replace my 01 F250 5.4 and I'm pretty stoked. There are several problem (some i knew about, some were surprises) 1 of which is the starter. The guy I bought it off said that every 100 starts or so (more like every 4-5) the starter sounds like it free-wheels but you just wait for it to stop, turn the key again (sometimes twice) and it engages and starts (although it takes a few seconds of turning over before it fires up).

I have a buddy with the same truck and he has had to replace his starter many times and I read in an old log book from the original owner that he had replaced the starter every 25,000kms (15,000miles). I am not the kind of guy who likes to fix things to have them break again.

SO my question is, WHY do the starters on these trucks keep breaking? What is the weak link? Is it possible to re-build one with better parts at home?

Is the problem partially because my batteries are only 650CCA and 750CCA and it takes more to turn this beast over? Could it be a bendix issue?

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Strange Turbo Sounds And Hard Shifting Into 3rd With TS6

I put a ts6 on my 2001 7.3. I love it shift points are better and truck has a lot more power. But I've noticed when I shift truck shifts into 3 (especially going uphill) I get a really weird turbo sound where it acts like its gasping for air (I have 6637 air filter) and then it shifts kinda rough into third. If I put chip on stock setting it doesn't do either of the things I described. Do I have loose turbo boots somewhere or possible bad turbo bearings?
