Ford 7.3L Power Stroke (1999-2003) :: Engine Rebuild But Won't Start
Jun 12, 2016
2002 7.3 rebuild and installed in the truck but won't start ... Everything is new other than hpop and injectors they came out of a perfectly running engine.
The truck is making enough oil pressure to fire the injectors the first couple cylinders then it quits kinda like a cold start with bad glow plugs. Fuel pump was working perfectly when the engine was taken out of the truck and is still building pressure enough to get some black smoke from the exhaust after cranking for about 15 seconds ...
The hpop reservoir full every time I check it and after cranking for about 15 seconds the oil gauge in the dash for the lpop jumps up to its normal place.
Injectors got new o-rings when they were taken out of the running engine. I'm not sure what else could be keeping the truck from starting.

Now that I have been driving for a while I kept seeing this light come on/off and I did a video below - I don't generally flash my lights so don't think I am aggressive - but I wanted to make sure to capture the video and the light coming on.
I was thinking valve cover connection the 50 cent mod - and maybe it's all coincidental - but I did have to pressure wash the troph where the oil collects and maybe something else got knocked loose.

Transmission rebuild? I seen a few threads where people talk of it but no follow up. I've heard it takes special tools but then so does a lot of things we shadetree on our own....

I have this 99f250 and it has a 273f, the transmission side of the case has threads stripped so I am about to remove and retap them. While its out should I consider rebuilding this thing? 197k miles, operates decently although the rear bearing on output side is my first thought to replace from mileage only.

I was hearing a clicking noise on my passenger front wheel when rotating by hand.
Paul suggested I remove the ESOF hub and see if it is the wheel hub or the ESOF hub. It's the ESOF hub.
So I'd like to rebuild it for sure, it also has a nicked o-ring, so that accounts for part of the vacuum leak
I'd like to service the driver's side, too, while I'm at it. It doesn't exhibit any issues, so just regular maintenance stuff there.
Parts lists?
As always, I'll take pics in return

My '01 f350 up and running the last 5 years. The truck has 130,000 miles on it and the transmission quit on me two weeks ago. My mechanic pulled the tranny and sent it to a very reputable rebuilder for a complete rebuild. My mechanic then reinstalled the tranny. I picked up the truck and when I paid the bill my mechanic told me that the rebuilder provided a new 4-plate torque convertor and that I would hear it rattle when I was at stop signs, stop lights etc. and that this was normal for these types of torque convertors. I have searched this forum and found all kinds of reasons for this rattle. None of which tell me this noise is normal or should be expected. I have no problem going back to my mechanic and discussing flex plate cracks, engine/tranny misalignment or any of the other causes...

I am about to purchase a 2001 F450 7.3L with a 6 speed ZF6 that has a slightly worn 2nd gear synchronizer. I will be rebuilding this transmission with a friend and was wonder if there is any documentation available to assist with the overhaul.

My truck (02 7.3L cc) started making a grilled ding type of vibration when I would let if the throttle. I felt the axle going into the rear differential was a bit loose, so I took the cover plate off. The pictures below show where the pinion I think is hitting, sort of like the bearing is allowing front to Rear differential scaring from movement. Rear movement.
How difficult is a rebuild, and is there anything I should be careful of?

Had to do the icp sensor originally. went in from the top and discovered my oil cooler was failing too. so i did that. with weather (too tall to fit in the garage) and life getting in the way it's taking me 2 months a little here n there to actually get it done so she's sat for a while. yesterday was moment of truth to get it started again. the batts were old before i started working on it. so i replaced those yesterday.
I've tried and tried to get it to start and it won't turn over. it did for one tenth of a second try. nothing since. I saw that my shifter wasn't exactly in park so i wiggled it and tried to crank it again and now it won't even crank. I have a feeling somehow the transmission isn't reading in park or neutral so it's refusing to crank. I really don't want to tow it.

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.

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.

2003 F350 7.3L 164k miles. Got towed in with hard to start cold complaint.
Hooked it up to the Snap On Verus Pro scan tool and we get up to 3000 psi on the ICP cranking, IPR value seems within spec, we have rpms over 100 on tool, pulse width within spec, computer voltage above 10v while cranking, verified output of glow plug module (California) and glow plugs get voltage for approx 50 seconds @ 80 degrees farenheit, glow plugs all read 0 ohms resistance.
injectors do NOT sound the same during buzz test.
Vehicle takes EXCESSIVE cranking cold to eventually get it started. LOTS of cranking. Just had to replace starter and a battery because driver burned em out. It feels like the vehicle shakes when it gets running. Black smoke when revving cold. Sometimes white smoke while cranking.
Once the engine has been warmed up, it starts perfectly every time.
I have spent two days in the engine bay looking for chaffed wires and doing diag and my current diagnosis is bad injectors. I feel there COULD also be high pressure oil leak, or a mechanical issue such as low compression. No compression guage yet for this truck. We have the ICP and IPR fittings to do a shop air test. Recently did a 6.0L and went thru everything and eventually diagnosed it as bad HPOP. LOW ICP pressure.
I noticed two of the cylinders were at maybe 8% Perdel on the data. Seems too high. Also, it "passed" the KOER self test and "passed" the injector buzz test with no codes after, but the audible sound of injectors didn't "seem" right to me, but I am new to these engines.

I have a 2000 f350 7.3 got a check engine light that turns off when rpms go up and a slow start. My mechanic said that there were no codes being blown, what is going on?

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.

I have a 2000 7.3 f450 having some electrical issues. When you turn the key on sometimes the dash will start ticking and left side light flashing...engine will turn over but it won't start. The ticking is coming from under the hood relay 32 (you can hear and feel it clicking). Book says its injector driver module power relay. A lot of the times it will start fine other times it will be running and just die (prob because of this issue) happened once when I was driving.
What to check here already replaced the relay still have the problem.

Last November I forgot to plug my truck in and it got down to 0, my girlfriend tried unsuccessfully to jump start it. When I got home I jumped it and got it running. I took it down to a heated shop to troubleshoot the glow plug circuit. I discovered it was not getting 12v to the glow plug relay. Also I started it and tried to back it up in the shop, when put in reverse it killed the engine, not lugged it down it was like you shut the switch off.
Also I discovered if you turn the lights on it kills the engine immediately. It will not crank with the lights on either. So far I have replaced the computer,ignition switch,batteries, and cam positioning sensor. Now comes the weird part!! I decided to get it running and pull the bulbs out of the back up lights I pulled the drivers bulb first then the passengers side bulb. When I pulled the passengers side bulb it killed the engine.
It is not my daily driver so it still sits in my shop. I have a hunch it's a ground issue but I've checked and cleaned up all the grounds I can find and it still has the problem.

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.
