take the fuel filter cap off and check for rust in the housing

First off, IT'S COLD, that's what a diesel does when it's cold, second, revving it like that is the WORST thing to do. It just needs to warm up and it will be fine.

Gee,,, none of that looks normal to me....

He's in FL, that's a LOT of smoke!

The "tapping", I dunno, hard to tell in a video, could simple as an exhaust leak (manifold, up-pipes, etc.) But, it's not running right.

Does it ever smooth-out?

This really is the kind of thing that's going to be impossible to diagnose over the internet He should take it somewhere and get it scanned by someone who has the right equipment (forget AutoZone and PepBoys, you have to find special equipment to scan our trucks)

fuel problem

[dburress]

Although a friend posted this, that is my truck. I have 3 of them and have had many others. All 7.3's This is the ONLY one that does this. On the same morning my ohter 2 trucks started with only a few seconds of smoke.
This is not normal diesel behavior.

I have taken it to Ford to have it scanned. They told me #3 injector was slamming so I replaced it. No change. I have been told it is a different injector, injector cups, flex plate, exhaust leak (I DO have an uppipe leak), rods, piston etc.

I don't want to keep fixing things (like the up pipes) if I am just going to have to replace the engine. I would like to know where a GOOD diesel guys is near Tampa that can actually tell me what the problem is, not just guess.

Any ideas???

if you have injector problems it could be the idm or the filter in the sender is clogged which is a common problem in 7.3s. check the condition of the fuel filter and check fuel restriction to the pump

I'm not mechanically inclined. But my 2000 7.3L was doing almost the same thing after it overheated from blowin a piston. Right now it's sitting at the Diesel Performance shop for the 2 months. They have yet to pull motor to start tearing things apart to see how the crank is n all. Hope you make out better then i did. My did this after it overheated and we were trying to diagnose the problem thinkin it was just head gaskets. I just wanted to mention it probably not ur problem but thought i would try.
