Ford 7.3L Power Stroke (1999-2003) :: Truck Harder To Start After Long Cranking

Background on the vehicle, Last week installed Swamps 200cc/30% injectors with a 38r. Had swamps reburn my chip for the new upgrades.

But heres the problem i noticed starting the truck was a little harder ( longer cranking ) till it would start never thought of anything since i read air gets in and can cause it but then yesterday and today its taken 30 minutes to start the truck since i have to do a trial and error.

The truck just seems like the batteries are being drained or something along those lines. i also noticed my gauges keep resetting back to blue( default color). Today I plugged a battery charger up all good voltage i charged them so both read 14v and still no start. So a couple of attempts at starting with chip in and ICP on nothing

I unhook the chip and ICP get a half start then eventually it starts. After then i can hook it all back up and it starts good for the rest of the day but for what ever reason after it sits all night it doesn't want to start up right away. I'd like to figure it out today since id rather not wake up at 4am and attempt to do this all before work each day.

I noticed that my gauges would reset to the default color after each turn off. So i unscrewed my ECU and then redid that to make sure its tight. along with making sure the chip is seated properly. after that it stopped resting my gauges. Whether that's the issue or not i cant say but ive been checking my HPOP oil level since i stopped driving it around 1400. and hasn't changed oil levels are good. I plan on starting it before I go to bed around 2200-2300 just to check and see what happens.

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Truck Won't Move In Drive?

I have a 2000 Excursion diesel 7.3. I drove it for an hour yesterday and it drove great. When I arrived home I left the truck running and put it in park. Checked the mailbox and jumped back in the truck and put it in drive and it would not move. Tried FWD and reverse. Moved a little in reverse.

I turned the truck off then cranked it back up put it in drive and it drove fine..... Took it for a test drive and seems fine.

Did the same thing today. Went to drop my kids off and I put it in park and left the engine running. Put it back into drive and it would not move.

Turned the vehicle off and back on. Put it in drive and it drove off fine.

Fluid is full, red and no burnt smell. Wondering if this is converter or electrical and how long I can drive it like this.

Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 Truck Stars But Won't Drive

I have a 2002 f350 7.3. It was running fine 2 days ago. After I put some diesel in it my water in fuel light came on. I drained the water out and took all the fuel out and put fresh diesel in it. It starts up fine and idles okay but when I try to drive it it looses all power and acts like it's starving for fuel and almost dies. It was smoking white smoke for a little bit even after I took all the water out but now it's black. What it could be.

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 7.3L Power Stroke (1999-2003) :: Harder To Start In Morning

Replaced cups 3ish years ago
Replaced IPR (non- Motorcraft) and ICP last year
New (not remans) PIS Stage 1 injectors with Hydra Flash October

Truck has been running and starting (down to 19 degrees) like a dream since the new injectors. After the last fill up the truck has been harder to start in the morning and if I don't let it warm up till at least until the needle moves it will stall and be difficult to start. Once started and up to temp it runs just fine but will definitely take aa few extra turns to get started whether cold or hot.

There is CEL, I don't smell or see any diesel in the coolant, oil looks good and the diesel in the filter is kind of a clear blue? The way it acts when it stalls is kind of like when the IPR went bad the first time... kind of. The few times I was able to get my phone connected fast enough I saw and IPR duty cycle in the 90s flash and a HPOP pressure of 1500 or so flash all while the truck is barely hanging on to an idle.

Ford 7.3L Power Stroke (1999-2003) :: Hard Start Getting Harder

My e99 f250 has been getting harder and harder to start over the last year.

I think one of my batteries is dying or dead but it still cranks fast while it does.

For instance when I tried starting today it seemed to crank just like normal but their was some relay clicking inside the cab that was abnormal.

My understanding is aside from cranking no power is required to start the motor? what if the dead battery is taking some cranking amps from the good battery preventing the computer from getting juice?

would the truck throw a code if it was a glow plug?

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) :: Extremely Slow To Startup / Starter Is Spinning Over Quickly

My brother has a '99.5 with about 130k on it. It's extremely slow to startup even the the starter is spinning it over pretty quickly. I pulled my Edge CTS out of my truck to get some #'s off of his. At idle mine has about 700+ ICP, his has about 480. My IPR is about 14%, his is about 10%. The only other obvious things noticeable is that his oil pressure gauge takes 3+ solid seconds before it comes up. Once it's running, it's seems normal and ICP & IPR match mine under full acceleration. The only other thing that is odd, while cranking his volts drop to mid 10's but isn't turning over slow. Where to start?

Ford Super Duty (1999-2016) :: 2000 - Extremely Hard Ride - Steering Wheel Jerky Over Bump?

I'm completely aware a lifted truck will not ride factory and most likely ride harder. But this is ridiculous.

So I bought a 8" super lift for my F250 7.3 2000, although the price is very cheap at that shipped to my door debating if I have messed up either with the brand or somewhere because I feel like I went from a casual ride in my lovely 7.3 to feeling like a horse carriage of a few century's ago.

Lift is setup with lift leaf springs in the front, one add a leaf in the rear with a block, and 4 new shocks and all the other hardware included to do the lift.

I'm wondering if it's possible the springs are installed wrong, or the shocks are just that bad or if there a weird issue I've over looked.

Tire pressure is set to 35-40 psi all around on toyo open country mts, (which I was running before the lift so that hasn't changed) but I mean this is so stiff that when I hit a bump my steering wheel jerks and I feel like my suspension has absolutely no flex in it. Debating on returning to stock or not at this point...

Ford 7.3L Power Stroke (1999-2003) :: Truck Won't Go Over 45 MPH

I have a 2003 7.3. Suddenly a week ago when I left work, I noticed my truck wasn't picking up much, but i was in a 40mph zone. I then jumped on the freeway and noticed the truck would not go over 60mph. Once I exited and got on another road with a 55mph speed limit, the truck would not go over 45mph, I had the pedal pressed all the way down and would not go over 2000 rpms. Also, for the transmission to shift, I would have to let off the accelerator.

Ford 7.3L Power Stroke (1999-2003) :: No Power - Truck Will Crank For About 15 - 20 Seconds Before Turning Over

I have a e99 f350 7.3 all stock. I have no power. The truck will crank for about 15-20sec before it'll turn over. I just purchased the*AE*but am fairly new to understanding it all. In idle its a little rough and when I drive I can only stay in the neighborhood because of fear of getting rearended due to very slow acceleration. Whats weird is that when i have no power while i am driving ill keep the pedal down throw it in nuetral and my rpms and*icp*pressure jump up right away. Things I've replaced:

Icp*sensor
Fuel pump
Pcm
Tps
Cps
Ipr
Dropped tanked and cleaned screens

When cranking my*icp*pressure climbs slowly to right under 500. I dont know what else to do ive been working on this truck dor two months some days 13hs straight, I am feeling defeated. Codes p1249 1211 1209....

Ford 7.3L Power Stroke (1999-2003) :: Truck Wouldn't Go Fast / Plenty Of Power In Low End

2002 f250 7.3l diesel...

I got a new radiator and the tranny fluid was the worst the mechanic had ever seen. He serviced it and warned me that it might not be long for this world. I broke my flexplate and so I had to pull the tranny, and I decided to throw a new torque converter in because it was giving g me symptoms like a broken sprag( it wouldn't rev up or do a brake stand in gear, therefore slow takeoffs).

I was recommended to replace the tranny, I decided I could do the job again down the road if I needed to. About two thousand miles down the road I had a hard shift going from overdrive down to get up a hill and about 10 miles later the truck started slowing down....I couldn't give it enough pedal to keep it going and the engine sounded rough.

I pulled over and checked fluids and everything was fine, truck idled fine, bright red tranny fluid not burnt at all. Pulled on to the road again and it pulled fine until about 40 mph and it wouldn't go any faster. I got it towed home and ordered up a tranny from Ford figuring it must be toast, but I thought I'd throw it out to the forum to see if there is any other troubleshooting I can do before I install the new one in case it is some other problem or some electrical harness or something, or if that is a pretty standard reaction to a fried tranny.

Engine runs good at idle, shifts perfectly to drive and reverse, drives forward and back(I'm very hesitant to drive it out of the driveway in case I can't get it back in). Only happened two times before I decided to tow it. Temps looked fine on the gauges, fluid was a little overfilled in the tranny, but again, not hot or burnt.

Ford 7.3L Power Stroke (1999-2003) :: Truck Would Stumble And Lose Power / Idles But Won't Rev Up

Problem started 2 days ago, driving around and my truck would stumble and lose power. Give it gas, won't rev up but it cleared and ran fine for a mile or so then it comes back (off and on all the way home). Check engine light didn't come on the first few times, came on a couple times on the way home (maybe 4 mile trip) but goes off when the truck runs fine. Thinking it was maybe the fuel pump (got 140K on the stocker). Talked to a few friends, some thought it was algae build up in the tank that was clogging the filter on the pump, underhood filter changed a couple hundred miles ago. Looked fine with slight brown build up at bottom of bowl when I replaced it.

Ran it around yesterday with a friend of mine and his scan tool hooked up, acted up once, check engine came on for a few seconds and shutoff. No code and for some reason we couldn't get it to live data while driving. I dumped in an algae eater yesterday and left the truck overnight since I had to work. Got home this morning to run her around the block to circulate the eater. Truck started and idled fine, went to pull out and she won't rev up, pumped the gas and NOTHING! Check engine light is on now but don't have a scan tool handy to read it. I heard the truck will store the code?

What this problem might be? What's a good scan tool for our trucks that can live data as well? CPS is good and already did the UVCH mod.

Ford 7.3L Power Stroke (1999-2003) :: Transmission Slipping When Put It In Drive

My tranny is acting odd. I put in drive and seems to slip a lot in 1st, barely even move at some times. If I put it in 1st with the shifter it goes in and grabs then I can shift up to 2nd or drive and there aren't problems. It drives normally when not from dead stop.

Transmission has 50k miles on it since replacement. Fluid level is normal. I don't tow and drive it particularly hard. I will have to go back and look at miles since last fluid change. I should be right around 30k miles since last change.

Ford 7.3L Power Stroke (1999-2003) :: Can't Drive - Sway After Leveling Kit?

So I went from a 3 inch to a 2 inch leveling kit. After tightening everything up the sway bar was a hair off. I pulled it out of the garage and got it lined up. Fast foreward the next day and went on a 200 mile trip hauling an empty goosneck and noticed it one time. The day following the the truck has went into this horrible sway through the tires back and forth that makes it undrivable. Looking at tie rod ends the one at the pitman arm is shot. I order the whole front steering kit from xrf and I'm going to replace. I know I also have some play in the box but I have for awhile. So what else would there be to look at? I need to get this fixed. I will update after the steering is put back together.

Ford 7.3L Power Stroke (1999-2003) :: Tranny Slowly Go In Drive

Tranny rebuilt, truck in sig, and beefed up 2 1/2 years and 30K miles ago. Recently started going into D after 10 to 20 seconds after putting it in gear, cold or hot. Very frustrating, especially when trying to maneuver a trailer.

Transmission builder has been running his shop for 20+ years, all makes and models, not Ford specific. I choose him because he runs a local business, has a good reputation, and happens to live less then 1/4 mile from me.

I have searched the forums, and read where Mark says this is loose valve body bolts, or forward drum going out. Builder can't grasp where it would be drum seal if it doesn't do it all the time, which it doesn't. He said it sounds more like something electrical, but there are no codes stored on pcm.

Builder also said he would pull tranny to check drum. Does this sound like I'm moving in the right direction? Or can it be something else?

Ford 7.3L Power Stroke (1999-2003) :: Truck Runs Very Rough And Lacks Power When Cold

My truck runs very rough and lacks power when cold, even during the Texas summer. Once it warms-up, everything is fine. It's almost like turning on a light switch. If it's plugged in for a couple/few hours, it's smooth as soon as it starts. I'm assuming it likes the oil once it reaches a specific temperature. What my problem is?
