Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 Won't Start Intermittently?
2002 F350 7.3 intermittently wont start after I've shut it off, it runs fine but sometimes won't start when it's (warm)? Wait hour or more and it starts right up.
Is there something I can look for before I bring it to a mechanic?
Just to clarify I am a gal with little wrenching skills but I can look at videos and follow directions if it's not too involved.
Ford 7.3L Power Stroke (1999-2003) :: Hard Time To Start Intermittently
Just got myself a gently used Econoline E-350 7.3 Diesel and was loving it when she ran:
E-350 7.3 Diesel
Recently I have been having some charging issues. It started with it intermittently having a hard time to start, especially when it was warm. I carried a jump box with me and that always seemed to work. Then I noticed the voltmeter on the dash dropping. It went down to the 8 and I was like something is wrong.
Checked the battery voltage, it was at 9.6v. OK, maybe alternator isn't charging. Advance Auto tested the alternator, said it was bad. I replaced alternator. No difference. I pulled the battery and ran it on a conditioner to bring it up to proper voltage. It's now at 12.6v resting. Starts the van no problem. When running though the voltage doesn't increase to 13-14 volts like it should though telling me the alternator isn't doing it's job. Increasing engine RPM actually decreases voltage? Checked all the obvious things like bad grounds but everything seemed clean.
The only thing that was fishy was when I pulled the three way plug from the alternator, one of the pins had corrosion on it. I cleaned it up before installing the new alternator. I didn't do a diode test on the new alternator because I figured it was new, but hey maybe I got a lemon?
Anyway I'm going crazy trying to figure out where the problem is. All fuses are ok. Is there an external regulator or something I should be on the lookout for? Is there anything else that could be causing a non charging issue? The battery was manufactured in 2014 so it's relatively new.
And on a random note my ABS light is now on?
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Cranks But Will Not Start Intermittently
I have an issue with my 2001 f350 7.3 PSD. Intermittently it will not start. It will crank really quick, but will not even try to start. I think it is not getting fuel. There are no CEL codes and I have a WTS light and the tach is moving while cranking. I hear a clicking/buzzing sound coming from under te center opf the dash. When I hear that sound it will not start. checked fuses and relays and it started before. not sure if removing the fue made whatever reset. this has happened a couple times. Now it will not reset. When I remove the number #24 fuse under the hood, the clicking stops. when i crank it, but still doesn't start. When it starts in runs perfect. Drained the batteries trying to trouble shoot, but have them charger now.

I have a 2002 f350 dually with a 7.3 and 197k. At 186k it died while driving and I had it towed home. As soon as the tow truck dropped it the truck fired right up like nothing was wrong. Then it died again 2 days later. I replaced the cps, but the fix was replacing the icp and pigtail. Now it is doing the same thing again. It died on my wife while driving yesterday, i had it towed to the dealership I work at and it started and ran for about 2 hours with no issues. I hooked up the factory IDS and had a diesel tech look at it with me. The oil pressure, injector circuit and injectors, and IPR all look good. The batteries were a little weak so i replaced both of them. I drove it home yesterday, about 10 miles, and drove it around town today. Then i tried to jump start my 96 bronco and after about 10 minutes of running it sort of hick uped then 5 minutes later it died and would not start. I let it set for 30 minutes and it started and died after about a minute.

I have a 99 f450 with a 7.3. Here lately it has been "missing" when driving or idling, but only every now and then. When driving down the road it will start bucking and boiling black smoke out then the ses light will come on and like turning a switch everything clears up and it acts and drives normal.

I have an 02 crew cab SB 7.3L. The best way to I know to describe it is a sorta like a metal ringing noise. It just started this afternoon while pulling a 9k camper. It only does it under load. Boost stays the same and it happens in all ranges from 5psi to 15psi. It is intermittent. It sounds like it it coming from the turbo. I pulled off the boot and could not feel any play on the intake wheel.
After unhooking trailer and taking for a test drive I can not get it to do it again? The turbo was rebuilt about 4 years ago with a wicked wheel but has only seen about 18k miles since the rebuild. A quick look at the boots appear good but didn't get to take them off before going to work. I will try to post video.
Ford 7.3L Power Stroke (1999-2003) :: Battery Light On Intermittently After Replacing Alternator?
Alternator locked up in a parking lot. Replaced it and had to replace pigtail due to a loose wire in the harness. Now battery light comes on intermittently. New alternator is doing fine producing anywhere from 13.9v to. 14.4v. No output voltage correlation to battery light at all. The belt is still in great shape so I don't suspect slipping. Fortunately I caught the old one locking up almost immediately and had recently replaced the belt. Output voltage looks great. Are there any fuses for alternator?
Only thing I can think of that I did...when splicing in the pigtail that connects to the alternator, I briefly grounded whatever wire in the pigtail is hot. Was just a split second, but enough to see a spark and maybe enough to blow a fuse? I've seen people reference an "under hood" fuse box, but I don't seem to have one. My truck is a 2002 CC with just over 100k on the clock.
Ford 7.3L Power Stroke (1999-2003) :: Stumbling For The Last Two Years Intermittently / P1316 Code
I'm running a 2000 f250 7.3. The truck has been stumbling for the last two years intermittently. I did the 50 cent mod last fall to the uvch's. Changed CPS, idm, air flow sensor. This last week it finally threw the p1316 code so I have something to go off of. Trucks falling on its face so I parked it. Tore it down last night. Ohm tested all the injectors last night cold and all read around 3ohms. Tested the uvch's and continuity looks good on both sides. Tested them through the valve cover seal, tested fine. Tested them through the first harness and fine. All I have left to check is all the way to the idm. Still no luck finding the problem.

I am still trying to debug my 7.3 running sluggish in the 1200-1800 rpm range. The problem is intermittent. I checked the wiring harness under the valve covers to verify they are plugged in and there are no opens in the circuit. I replaced the crankshaft position sensor and the high pressure oil sensor.
This will run fine one time and a few miles down the road it will chug and smoke out the exhaust until I either get into the accelerator or back off and re press the accelerator. Again, it does it intermittently hot or cold.
I ran both a cylinder contribution test and perdels with a Snap On Verus. The cct passes everytime. The perdels have a couple of cylinders 5-6 and 8 fluctuate between 0 and 1.80% with #8 up to 2.5%.
My question is. Do the cylinders in the test correspond to the actual cylinders in the engine? Reason I am asking is the Verus does not follow the firing order on a gas engine. The cct is in order of 1-8 and I have to correlate the cct order to the firing order. Found this out the hard way when I had a bat cop on a 5.4 and replaced it only to have the same cylinder still show not firing.
I got out the graph leads and tested the cylinder and pulled the injector thinking it was bad. Everything showed good but the cct still showed it not firing. I had to unplug each coil and watch the cct to determine what the true cylinder in the test was. It turned out to mimic the firing order so I am asking out of concern that cylinder 3 in the perdels is really cylinder 3 or a different cylinder.
Btw, the perdels all show 0% if the transmission is in drive. I would have thought that a load on the engine would have showed higher perdel percentages with a load on it.
Ford 7.3L Power Stroke (1999-2003) :: Lost Power While Driving And Won't Start Back Up
I have a 2000 f350. Lost power whole driving and won't start back up. I have checked all my fuses and relays several times. Have no power to the fuel pump. Tried running a hot wire straight to the pump and still nothing.checked my emergency cur off switch and there is no power there. Also my WTS light isn't coming on now. Tried checking the heater bowl and no power there.

Went to start 'er up, key spun forwards, power came on but no start, no click, nada. Turn key back and power stayed on, back forward and no resistance whatsoever power stayed on. Took screwdriver, jumped starter relay and viola away we go. Get home, get cylinder out of hole and the tip is broken off down in the column. BTW, had to disconnect batteries to shut it off. I drilled hole in the tip still in the column, insert screw and no come out. Must need to be turned somehow first I'm thinking.

New to the forums, not new to fords. 1999 F350 7.3L Diesel. This has been a work truck and has seen multiple devices in and out over the years. I removed the last crap for GPS tracking etc from the last owners. The truck has worked well for a long time since until...
I'm moving slowly to a different state and so the truck got parked for 2 months. went to start it and nothing. the dash comes on and all the lights come on but when you turn the key to start the power drops and nothing.
Testing so far:
replaced the fender Solenoid
tested the starter motor and solenoid -passed
replaced the ignition switch
tested continuity of the hot and ground wires to the fender and starter and everything passed
When I shorted across the fender solenoid the starter works and tries to start the truck (unsuccessfully so far)
So the wire that goes to the fender solenoid is not working and where to trace it to and what needs to be fixed. Is there a relay or fuse besides number 30 that is in the way? where does the magical wire go so i can check its continuity?
I am stuck 800 miles from where i need to be and I am stuck here. I don't have the cash to get a mechanic and my mechanic friends are stumped. I do have a Snapon modus tester, what to do with it.
FYI the batteries are new and fully charged.
Ford 7.3L Power Stroke (1999-2003) :: 1999 - Cranks But Won't Start - Water In Fuel Light On?
My 99 F350 cranks, but won't start, and the "water in fuel" light on the dash stays on while cranking. I have never paid close attention to it in the past. Is it supposed to be on while cranking?
I drained the water from the yellow lever located on top of the engine, and tried to start it. The light went off for the first few cranks, but again the truck still will not start.
I just came from a 10 hours round trip to NC. I filled the truck up two times from gas stations on the way. Is it possible that the fuel is bad? I drove on the same fuel almost 3/4 of this tank and now at the last 1/4 I am having this issue.
A little update:
I took the top of the fuel bowl off to see what the filter looks like, and it is nasty and completely black. I could not tell if the fuel in the bowl contained any water, but it looks greenish and uniform, no the obvious separation that happens when you mix water and oil.
Could the fuel filter be the problem?
A little history about the truck. It's always hard to start if cold and not plugged in overnight. I know it's the glow plugs relay, so I just keep it plugged in all the time until I get a chance to fix it.
IDM was acting up shutting off half of my engine, but I took it off, cleaned it, plugged it back in and it has been working fine for over 2 months.
Ford 7.3L Power Stroke (1999-2003) :: While Driving F250 Start Chugging / Lose Power And Shut Off
I have a 99 F 250 7.3. It runs fine at idle even for a long time. When I drive around the block a couple of times it will start chugging and lose power and shut off. I have been mixing fryer oil with the diesel. I changed the fuel filter, oil change, crank sensor and fuel pump. I added 15 gallons of diesel and diesel treatment. Pulled fuel filter and bowel is full I'm not sure where to look next.

Cooler weather has arrived and my 2000 f250 won't start. Wait to start light is coming on, no power passing through the two relays on top of the engine. Are both of these for glowplugs? My 97 only had one. How do I diagnose relays on this truck? If you cross out the two relays truck fires right off so I know the glowplugs themselves are good.

My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.
