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) :: 2000 F350 Idles Fine But Runs Rough After Warms Up A Little

2000 F350. Starts great. Idles fine. After it warms up a little, it will run rough and lose power like it is only hitting on a few cylinders. It will eventually stall unless I push the clutch in and bring it back to idle and then it smooths back out. I figured it was starving for fuel but I can rev it with the clutch in with no issue. I ran it up to 2500 rpm and held it there with the clutch in and ran perfect.

I let the clutch out and start rolling....missing again. The check engine light does come on but my scanner says that there are no codes stored. If I idle it, it will smooth out, and the light goes off. All I have done so far was change the fuel filter which was almost plugged shut and the housing was full of rust looking debris which I cleaned out. BINGO! Nope. Same issue.

I am really at a loss as to where to start. I bought this with 120k on it and it now has 170k and I have not had to do anything other than routine maintenance.

Ford 7.3L Power Stroke (1999-2003) :: Idle Surging / RPMs Will Drop By 300 Or 400 For A Few Seconds

My '03 7.3 is "surging" on idle. When warmed up, and idling, the RPMs will drop by 300 or 400 for a few seconds and then will correct and shoot back up. It cycles like this (every 5 seconds-ish) continually . I just put in a new IDM and checked the UVCH - is there a separate idle control mechanism that I need to have a look at? (2003, 7.3, 214K, stock).

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Crank And Start Then Idle For Few Seconds And Shut Off?

I've developed a problem, usually when starting, that the truck will crank over, start and idle for a few seconds and then shut off. The few seconds it idles it doesn't get any throttle input. I'll crank it back over taking a little more than usual to get it started. When it does start it seems slightly sluggish but that quickly, like almost immediately goes away and the throttle is working again.

Oh, 2001, 7.3 stock w/200k

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Take 10 Seconds To Crank At Operating Temperature?

I have a 2000 F250, 300k. Starts beautifully when cold, takes 10 seconds of cranking when at Operating Temperature. Did the injectors and plugs in September, kept doing it and now that it's summer it's getting harder and harder to start. Just replaced the ipr, still doing it. Gonna do an overdue oil change tonight or tomorrow, I'm hopeing that will improve it. I can understand 3 or 4 sec of cranking, but not 10. Truck hads no drivability issues whatsoever. Will an ICP fix it? Change to a heavy-duty 20w-50? (Last oil change was delo 15w-40) The code reader that I have is really basic, and only shows me RPM and map.

Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 Starts And Runs With Rough Idle For About 10 Seconds When Cold

I have an issue with my 7.3.... the truck will not start if it sits overnight without being plugged in, even in 65 degree weather. It starts and runs with a rough idle for about 10 seconds after its been plugged in for an hour, after the rough idle is gone it runs great .. it will Stat back up as long as the truck is warm (70+).... I've replaced the batteries, glow plugs, starter (it was going bad) and fuel filter. .. also replaced the gpr today. ....

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Smooth Idle But No Power

I purchased a 2000 excursion with the 7.3 a couple of weeks ago. The guy said originally in the add that it need #2 and #8 injectors replaced. When I went and looked at it he had already replaced them and said the it still has no power and needed the remaining 6 replaced. I purchased it as it was a good deal thinking I should be able to get it fixed for worst case a set of injectors. BTW the engine has little to no blowby and starts easy and idles great.

The problem it it will not build any boost (has external boost gauge). Actually the gauge only shows vacuum. With the truck in park or neutral you can slowly rev the motor to 2500rpm and all seems fine but as soon as you break past 2500rpm it sound like it is missing and starts blowing white smoke. The smoke smells like when a diesel heater runs out of diesel. If you try and drive it it has NO power and will not move out of its own way and will eventually start like it is missing and blowing white smoke.

The previous owner replaced the following:

#2 injector
#8 injector
UVC gaskets
MAP Sensor
Wastegate solenoid sensor

The first thing I did was start looking at the no boost issue and pulled the turbo. I deleted the EBPV while i was there. Also the turbine wheel was in very bad shape so i replaced the turbine wheel, shaft, seals, bushings and installed a new compressor wheel 5+5 wheel off ebay. Reinstalled turbo and the symptoms are the same. I also replaced the clamps on the spider with Tbolt clamps instead of the worm gear styles and it psi tested all piping and intercooler to 30psi with no leaks. Also the up pipes have already been replaced with the bellowed style so there are no leaks and it has a 4" straight exhaust.

I have since ordered oring kits for the injectors and also ordered the fittings for the fuel bowl so i can check fuel pressure. it has a new air filter, oil filter, oil and fuel filter installed.

The ICP sensor has oil in the plug but if i unplug it the symptoms are still there.

I have also used a scanner and the ICP pressure is approx 500psi at idle and the duty cycle is about 11% at idle. Also the HPOP looks to be new as it is very clean compared to the surrounding parts and i have checked the HPOP reservoir and it is full to withing 1/2" from the threads.

2000 Excursion
7.3
205000 miles

I am assuming that the injectors are original other than #2 and #8.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 Rough Idle Sometimes

I have a 2000 F350 4x4 CC 7.3L 323,000 miles auto trans. I have removed my tuner just to make sure that it was not the issue. The truck will run fine then all of a sudden the idle will rise then fall or shudder or go up and down and sometimes it will just Die but it always restarts. No trouble lights at all. I am not sure what is causing the issue?

Accent LC (2000-05) :: 2004 - Starts And Idle Fine For A Few Seconds Then Dies - No CEL

A few days ago, I went to start the car, and it will start, and idle fine for a few seconds, and then begin to run crappy, idle down, and die. I tried starting it, and giving it some accelerator pedal, and it dies. I changed the timing belt, idler pulley, and tensioner this summer, so I'm ruling out a bad timing belt. There is no check engine light, and I replaced the plug wires because when I removed the cover, I noticed one of them was worn in a spot, and the wire shielding inside the rubber insulation was visible.

Ford 7.3L Power Stroke (1999-2003) :: Fuel Pump Runs For 20 Seconds At Key On / Long Start Takes About 6 Seconds

This applies to a 2001 F-350 with 73,000 miles on the engine. Engine oil level is good, batteries charged, HPOP reservoir is full and passes Cody test with flying colors. Fuel pump runs for 20 seconds at key on. Start takes about 6 seconds. If I shut the key off and restart immediately it starts in under 2 seconds but if I wait about 30 seconds it's a 6 second start. Here is an AE that I ran on it, it has me stumped. FWIW it seems to start quicker when AE is hooked up. ?? An odd whir type of noise comes out from somewhere under the hood when I first turn the key on and when I clear the codes with AE.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 - Noise Like Exhaust Rattle Or Vibration At Idle

I have a 2000 Ford F350 7.3 with the auto and 262,000 miles on it. As far as I know everything is stock on this truck. It has been a great truck but lately its been making a strange noise. It almost sounds like an exhaust rattle or vibration but it is intermittent. Its not really loud it can be heard best in the cab at idle. I've looked all over on the truck and haven't found anything. I can't pinpoint where it is coming from. I tried starting the truck with the serpentine belt off no change.

I took the inspection plate off the bell housing and couldn't see any cracks the torque converter bolts appear tight, and the starter is not engaged while running. I've read a few forums on the torque converter going bad. It looks to me like its more the 99 trucks that had trouble with that. Did the torque converter issue carry over to the 2000's? Would a torque converter/transmission problem be intermittent?

Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 - High Idle / Over Drive Light Started Blinking

OK, truck is 2000 F350. I am heading on a 2000 mile roadtrip to Yellowstone for my wife's 40th birthday in two days. What was our rock of a vehicle is now causing me severe anxiety.

Over the last few days the truck has been difficult to start - almost stops turning over as if the batteries were low. So I ignored it because if I plug it in, it starts fine and if I drive it and it gets hot - it starts fine.

Tonight while driving - I noticed a high idle and then it went to normal - I thought it was weird and a few miles later at a stop sign it struggled at idle, sort of loping but not romping very high and the over drive light started blinking. When I got home when I went from drive to neutral it goes to high idle and then the overdrive light blinks. The first time it blinked it went off when I pressed the OD button - but now it continues to blink.

Would low batteries be the root cause of this? I will continue my search for blinking OD light but I thought I would get this in the queue in case this is bigger than I can handle. I have 48 hours to resolve this issue - leaving Wednesday early morning.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 - Missing After Start Up - High Idle - Got Codes P1316 / P1211?

Well, long story is that I starting have problems with my 2000 F350 Dually 7.3 PSD about 6 months ago ( ~10K miles ago ). I have sunk almost 5K$ in mechanics and the problem is still present.

By troubleshoot, I do not mean try this, try this, as that has been what is happening. I mean making test measurements and diagnostics. I am fairly mechanically inclined, but I am no mechanic. Looking for primers on how the 7.3 PSD works.

Symptoms: After the truck sits 12 to 14 hours, it starts and idles fine ( ~ 700 RPM on the 'Dash Tach' ) just as it has always done. During the first 5 miles of driving it, the SES light comes on and it sputters, stalls, and vibrates as if a couple of the injectors are not firing. It then clears up and the SES light goes out, except that it idles at about 1200 RPM ( 'Dash Tach' ).

It runs fine like this the rest of the day, If I shut it down it will start right up and run fine, but it has the high idles. Only if it is shut down longer than 12 to 16 hours do the symptoms, other than the high idle, reappear. The high idle is constant. Also mpg have fallen ( 13 opposed to 16 ).

It does not seem to be related to ambient temperature, or the amount of warm-up idle. I have idled it for three hours on startup and it is fine, until I drive the first 5 miles or so.

Now, I have had three mechanics work on it and they have replaced: the ICP sensor ( 3 times ), the Fuel filter ( twice ), drained, flushed and refilled the HPOP, replaced both sides of the valve cover wiring harness, put in a new IDM, fuel heater, CPS sensor ( 3 times ), fuel pump in fuel tank, EBPV ( not sure what this is ), and the last straw was saying the injectors needed to be replaced ( or at least the O-rings, but while we are in there you might as well ... ).

I bought a cheap code reader and it says: P1316 & P1211. I believe these are the same codes since day 1.

Ford 7.3L Power Stroke (1999-2003) :: Truck Turns Over Just Fine But Won't Start

I bought a 99F350 with a 7.3, it was not running when I bought it. Batteries good, new starter, turns over just fine, fuel pump works, but now I don't know what to look for.

Was testing ohms for my injectors and at the plug on top of the driver side valve cover, couldn't get a reading at all, tested the ohms at the pass. Side valve cover plug and got good ohm readings.

Ford 7.3L Power Stroke (1999-2003) :: F250 Truck Ran Fine Now Won't Start

Truck is a e99 f250sd 4x4 7.3 manual trans. The truck started and ran fine to work this morning. Went to leave this afternoon. Hopped in, put key in and tried to start it. Engine just turned over, never started. Thought that it didn't start because I didn't let the plow plugs warm up enough. Turned ignition off, turned back on and let wait to start light to go out. Same thing happened again. Just turned over but wouldn't start. As far as I can tell the fuel pump is running. Felt it vibrating while the ignition was on. What to check.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 Cranked Fine But Would Not Fire

Owning a 2001 F250 Extended cab with a 7.3 I have not had a lot of questions to ask fortunately.

My truck has spent a lot more time sitting than running lately and when I went to start it the other day it cranked fine but would not fire. Quick read on this forum and the first thing I found was how if the fuel solenoid had less than 10.8 volts when cranking it would not start.

I went down and checked the battery voltage and it was at 12.1 volts no load. I put the battery charger on for about 10 hours (time to kill) and when I pulled the charger and cranked it over, started with no problem.
