Need Help, i am stumped
Hi you guys and gals so i have an 02 7.3 280k on the miles, when u first start the truck up,takes a while to start, the truck runs great except excessive and thick white smoke. After a few mins the truck settles down no smoke but idles really rough and stumbles and has no power, will not move in its tracks. Ive changed the IPR checked fuel filter its brand new. Unplugged the icp and tried it with it unplugged no change. Im stumped what's my next move?
Also dont know if it has anything to do with it the truck was traded in but had sat for a while at least 2 to 3 years.

Hey Dalton,
Went thru this with a buddy of mine who bought a low mileage (50,000 miles) 7.3 that sat for awhile ... It ended up turning into a wild goose chase but we ultimately resolved the issue. To answer your question on the next move: install a new glow plug relay and report back. Also, where are you located? Just wondering for temperature reference.

Next move would be:
1. check for codes with a Powerstroke capable scanner (the ones at the parts stores are not Powerstroke capable but the workers don't know that and will tell you there are no codes because their cheesy scanner can't see them)
2. check fuel pressure

Good to know. With reference to my buddies truck we were in Elizabeth City, NC. Start with the glow plug relay to see if it makes a difference.
You mentioned after it takes a while to start, it runs great but then idles rough with no power. Does it feel like only half the engine is running? Meaning that you have a bad/loose UVCH (Under Valve Cover Harness).

Our trucks don't have sensors for fuel pressure, or EGTs. Those require add on gauges. The PCM reads all other info you will need to monitor. ForScan will show all that.
You changed the IPR, was it Motorcraft brand?

This could be the GPR or glow plugs.
2) do check the UVCH harnesses
While under the valve covers, look for the 50 cent mod.. I hope you need it.

First off... welcome to FTE!
Once the engine starts up and is running rough, does it eventually "kick in" as if someone flips a switch, and then run normally, or is it always running in the rough state?

OK. If it's like someone flips a switch, it is likely that one of the poppet's is sticking in an injector until the oil temp gets high enough for it to release. There are injector shim kits available for about $50 to address this particular issue. A handful of guys on here have done this shim job with great results. I have a kit waiting to be installed in my '02 F250 for the exact same symptom.

But it does it no matter how hot the oil is
i poured some hot shots stiction eliminator and fuel injector cleaner in it and idleed it up to 2500 rpm and let it set for 2 hours and it disnt make a difference
