Ford 7.3L Power Stroke (1999-2003) :: Turbo Boost Loss And Engine Starting After 2 Attempts

I've got a 2002 Excursion which has been giving me a little trouble lately. I've got a DP tuner, 4" exhaust, afe stage 2, and gauges (boost, trans temp, EGT). I've been running these for about a year now without any truck problems until recently

So I noticed over the past couple weeks it has gradually been taking longer for the engine to start. Started off by just having to turn the engine over a few more times. Now it has turned into having to turning over the engine for a few seconds, then turning it to off, then trying again. It always starts on the second attempt to start my truck and sometimes really hard where it blows out a little black smoke.

Not sure if this is a correlation to the problem above or not, but I've also been losing boost pressure, and I'm not sure when this started since I haven't been on the highway for a while. I noticed this because this weekend I drove on the highway and saw that I was blowing some black smoke every time I accelerated which has never been the case.

So I check my boost gauge and see that I'm sitting at like 3-5psi when I used to be at around 10psi+. I also noticed when I accelerated the boost pressure would increase like normal but then quickly drop once I stopped accelerating which is unlike anything I've seen before in my truck. I don't seem to notice a huge difference power or throttle response, but then again 95% of the time I'm driving under 40 mph to get to work. So this problem could have started the same time as the starting problem, but I can't say definitively.

What this problem could be, what to check or test?

Ford 7.3L Power Stroke (1999-2003) :: Engine Code P0683 - Surging / Near-stalling After Starting And Hiccup At Speed

I have a 2000 Excursion with the 7.3L. We bought it in February of last year with 81,000 miles on it, and it has 111,000 miles on it now.

First problem:

It threw a code today: P0683 indicating a communication issue between the Glow Plug Control Module and PCM Communication Circuit. Other than the code, the truck isn't doing anything out of the ordinary today. Drove it about 40 miles, up to 80 MPH, problem three below did show it's head once, but other than that it ran great.

Second problem:

Ever since we've owned the vehicle it has done a strange surging/near-stalling thing (for lack of a better word) when it's started up. It only does it occasionally, and the problem seems to appear, and then go away for several weeks or months only to reappear. Here's how it goes:

- Start truck
- After starting the truck immediately begins to surge (rev?) and then nearly stall.
- It will do this over and over, about one surge/near-stall cycle per second, until I tap the accelerator, at which point it stops immediately. So far it has never stopped on it's own, but has always stopped with a tap of the accelerator.

Up until recently I chalked this up to "huh, that's weird" since the truck has otherwise run fine.

Third Problem:

Every once in a while the truck will hiccup while it's up to speed. It only seems to do it at highway speeds, typically between 55-70, and the hiccup typically only occurs once.

The first time I distinctly remember it happening was right after I had replaced the Camshaft Position Sensor (approximately 5-6 weeks ago).

While digging around online I found one other guy say his truck started doing the same thing after replacing the CMP in his F250 with the same little plastic gray one I used. So that problem might be caused by that part.

My Thoughts:

It seems like the run-away favorite for fixing problem one is to replace the GPCM. I've dug through a couple hours of forums this afternoon/evening, and it looks to me like the GPCM is the culprit the vast majority of the time when code P0683 comes up.

I'm thinking problem 2 might be an ICP issue. I can't find any previous forums anywhere that describe the exact issue I'm having - or really anything very close. Maybe it's out there, but I couldn't find it. So I'm really grasping at straws.

Problem 3 could either be related to the ICP (if problem 2 is an ICP problem) or it could be due to the new CMP I installed (the cheap gray plastic one from Autozone). It's possible the hiccup has been around longer than I think. Half the time when it happens (or does it?) I can't decide if it was a hiccup or a bump on the road I didn't see. I am sure it's happening at times, but there are other times I'm not sure if it was a hiccup or a bump I just didn't see. So I think it's possible it's been going on longer than I realize, and I noticed it that first time because I had JUST been under the hood and pretty finely attuned to how the truck was running as a result.

I'm about to hitch my 35' camper to this truck and haul it a few hours and I'm not feeling real confident right now. Problem 1 hit today, problem 2 is more prevalent than every right now, and problem 3 has been hiccupping for 5 or 6 weeks. I'd like to get at least problems 1 and 3 sorted out before hauling 8,000 lbs if possible.

Ford 7.3L Power Stroke (1999-2003) :: Series Of Clicks And Chirps And Acted Like No Power When Starting

About 10 days ago following a heavy rain, I went to start my truck. It made a series of clicks and chirps, and acted like there was no power. Like dead battery or something. After fiddling get with the key and trying to figure the issues, all the sudden started normal door chimes....and truck started...no issues after that for several days.

Had another rain storm...same issues only this time took longer to get it to act normal. Once it did....no problems till today. This time wasn't a big rain...still acting weird. Battery's have power. ..it's not a battery or alternator issue I'm sure. Seems like a grounding issue if I had to guess....but can not tell where...or if that's really it.? No codes or lights once it acts normal.

Ford 7.3L Power Stroke (1999-2003) :: Suddenly Not Starting?

'99 F-250 7.3 PS 2WD Automatic 246,000 miles

Jumped in my truck a bit ago and it wouldn't start, although it is turning over. The "Wait to Start" light is not coming on and the Overdrive button on the shifter is lit up OFF and won't change with me pressing the button. I've checked all the fuses under hood and inside cab with multimeter and everything checks out ok.

Also, when it was raining last week I found that when I turned on my windshield wipers the truck would die. My solution to get home was to just flip it back & forth real quick every so often so I could see out the windshield.

Ford 7.3L Power Stroke (1999-2003) :: F250 Not Starting / Won't Fire Up?

My dad has a 99 F250 with a no start issue. Everything was starting and running fine one day. The next he gets a no start. Cranks fast and fine but wont fire up and start. He has a scangaugeII hooked up to it and his oil pressures and volts look fine. His tach moves when he is trying to start it. He checked the icp sensor and it had oil through it so he replaced it with a Ford part. Unplugged it and the scangauge pressure goes up but no start. He also replaced the ipr with a new Ford one just in case. He checked and is getting low pressure and high pressure oil. I am having him check the fuel heater fuse #22 to make sure it is not blown. He had the block heater plugged in all night along with a battery charger to make sure they are topped off as well. We have gone through a couple of the checklists on this site for a no start condition but nothing has solved it yet. If you need any info off the scangauge let me know and I will post the exact readings. I think he is sitting at about 200k on the motor. No major issues or problems until now. He is currently also pulling the ICM to check it out as well. No codes are being thrown.

Ford 7.3L Power Stroke (1999-2003) :: Truck Not Starting When Cold / Would Not Crank Up

I had issues with my F250 cranking last winter when the temperature dropped, so I changed out the glow plugs in the spring. I hadn't been able to truly test them yet, since it hasn't been cold, but the other morning my truck wouldn't crank up. It was 40 degrees out the night before, and it had been almost 24 hours since I cranked the truck, but it seems to me like the truck shouldn't have an issue in that mild weather.

I'm not sure what I need to do next to try and fix this problem, it's been driving me crazy and risks stranding me if I park for a while in an area where I am unable to plug by block heater in. The truck cranks fine when I have had it plugged in for a while, so I'm fairly certain it's a heating issue. I haven't done any tests since last year, but I know that the GPR was working properly last winter, which is why I changed out the glow plugs.

Ford 7.3L Power Stroke (1999-2003) :: Hesitation When Accelerate Especially Starting From A Stop

I have hesitation as I accelerate especially starting from a stop. It will continue until cruising speed. Funny thing is when I put the cruse control on the hesitation stops and it runs fine. If I want to accelerate while on cruse the hesitation starts again until I let off the accelerator. Is it the TPS ? I changed it two months ago.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F450 Truck Not Starting

I have a 2000 F450 with a 7.3. I am having problems starting it. Batteries are good, engine turns over strong. It has started a few times after a extremely long crank (so long I am sure I am burning out the starter). I have replaced the CPS since it was cheap enough but that didn't make a difference. I have unplugged the ICP and it is very oily inside the connection. Does this mean the ICP should definitely be replaced? The truck will not start with the ICP unplugged. Should it be able to start with the ICP unplugged? Other items I plan on looking at at the IPR and possible the IDM box. Am I on the right track?

Ford 7.3L Power Stroke (1999-2003) :: Intermittent Starting / Spin Like A Top But Not Fire

2002 7.3 PS TD.

Lately sometimes when I get in and start the truck all is well. Then the next time it will spin like a top, but not fire. New batteries. Then it will fire right up. It may go a few weeks, or days, then it happens again. Temperature does not seem to be a factor. It also doesn't matter if the engine is hot or cold. Once when rounding a corner at low speed, it just died, then started right up.

I recently changed the fuel and air filters. I think the glow plugs are getting old. In cool weather I turn the key on for about 1 min. before cranking. I have 110,000 on the engine with all original parts.

Ford 7.3L Power Stroke (1999-2003) :: 2002 Not Starting When Hot / Cranks But Won't Fire

2002 7.3 Power Stroke... I bought the truck about 4 months ago and I absolutely love it but over the last few weeks is has been acting funny at times, it doesn't do it all the time but it has been getting progressively worse, ill drive the truck all day and no problems when I shut it off and go to start it again it just cranks but won't fire.

* Batteries are charged and in good condition, oil is a little dirty but full, I have no codes or check engine light on, and my wait to start light seems to be working fine!
* If I supply a fuel source(starting fluid) the truck will fire but not stay running
* And let it sit for 15 to 45 minutes fires right up like there was never an issue.
* There are no blown fuses

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Died After Starting - Won't Restart?

My 01 4x4 F350CCD was having this "issue" where, after leaving it plugged in all night, I would start it up with no problems but then after idling for maybe 15-30 seconds it would just fade out and shut off. The first few times I would hit the key again and it would crank for an extended period but then refire and it would idle normally. Eventually I learned that if I held the idle up at around 1000 I could see the rpm drop slightly after starting but it wouldn't shut off.

About a week ago I started the truck and wasn't paying attention and didn't hold the throttle open and the truck shut off. This time after cranking it (probably way to much) it wouldn't start at all. I changed the fuel filter but that did nothing. I also notice that the tach does move to around 500 or so when cranking. I have not changed the CPS but a new one had been installed in May 2015. The engine is cranking but there is no white smoke or even attempt to fire.

Ford 7.3L Power Stroke (1999-2003) :: Intermittent Starting / Code P1280

My 02 f250 w/ 7.3 won't start. Cranks and nothing. No smoke or anything. For the last year It has had a intermittent starting problem, where I would drive it for 15-20 mins. If I shut it off like I would if I was at the fuel pump and then restart it, it wouldn't. I'd have to wait 30 minutes with a hood open and then it may start. Other times I would have to wait hours.

I tried replacing the crank position sensor, the fuel pump and filter.I did all this in the Last 300 mile . There's No change. After a week or two of sitting it won't start. What can I check and what can I try.

To add more info. Since I am not the original owner I pulled the computer that is located behind the ebrake to see if someone else had installed a chip, as I've heard that if that chip goes bad then the truck won't start. I disconnected that battery and pulled it. Negative on any chip. Put it all back together and tried again. No start. I borrowed a code reader tonight and pulled a P1280 code. I'm back to square one.

Ford 7.3L Power Stroke (1999-2003) :: 2002 7.3 ZF6 - Vibration Noise Starting Out?

I have an 02 F350 7.3 6 speed with only 86,000 miles on it ... Ive owned the truck about a year and a half now and ever since i can remember the transmission has had this growling/Groaning/Vibration sounding noise when ever Im in 1st or 2nd slow rolling with barely any throttle. Itll make the noise going slow and as soon as i let out on the clutch and start moving, but once i give it a little more throttle and start moving at a more proper speed for the gear, the noise fades away ... Id assume its just the transmission making noise due to the low speed and RPM when slow rolling or just starting from a stop.

Ford 7.3L Power Stroke (1999-2003) :: Starting Hard And Run Really Rough For About 10 Minutes

I have had my excursion for almost 4 years, I love this truck. but lately we have been having issues that we haven't been able to figure out. First it has about 390K miles on it.

I ALWAYS have to plug it in. it could be 90 degrees out and I still have to plug it in. if it Is plugged in normally it will start fine. but then when I go to drive it, it wont have any power until I get like 2 miles down the road. you can push the pedal all the way down and it will go like 10mph. but once it warms up its fine. if I forget to plug it in, I will have to plug it in for about 2 hours and then it will start hard and run really rough for about 10 min. And it will blow greyish smoke out the exhaust.

But now I'm having the issue of keeping it running. it will start and run for 5-15 min and then quit and I have to wait anywhere from 10min - 1 hour to start it again.
