THANKS everyone for the advice. It turned out to be the glow plug RELAY (looks like a selanoid), I did test the glow plugs (6 out of 8) hard to get to the plug by the turbo ,but the all turned out good, 01.1 Ohms, but the relay never had any output. Must of started on pure compression, hard when I wanted to go deer hunting and it was 24 in the morning. Replace the relay for $45, (1 time replacement guarantee) GOOD to GO now

That exactly was the problem. he added the Lucas then the temps took a dive, the oil I guess was too thick. He had to plug in his block heater every night untill he figured out what was going on. After he realized his mistake he changed his oil...again... amd things went back to normal.cArNaGe wrote:I've never heard that one. But I could see how that may happen. The injectors run off the HPOP (high pressure oil pump).Boots wrote:did you by chance recently add and additives to the oil? a guy I work with last fall added lucas additive to his oil. when it got cold his 7.3 would not start. come to find out you have to use the synthetic version of the additive in powerstrokes, or guess what... it will not start when cold!

Makes sense, all you are doing is adding polymer to your engine oil. If you want thinker oil, buy a heavier SAE grade.Boots wrote:he added the Lucas then the temps took a dive, the oil I guess was too thick.

My neighbor's 7.3 just went away on a flatbed yesterday. He made it to the front of my house when it started running real rough - sounded like it was running on 5 or 6 cylinders. He thought he was out of fuel, so I drove him to grab some diesel, we dumped it in, and it was still running rough ..... then I could hear cylinders dropping one by one, until it stalled and would not start. I took that strange round cap for the fuel filter off, and poured some diesel in there, tightened it back up, cycled the key a bunch of times, then cranked ... and cranked .... and cranked! Was only getting a very sharp knock on one cylinder. Pulled that lever & let the diesel pee out, refilled, and tried again. Long story short, it went away on the flatbed.
Probably something electronic, no doubt.

Looks like the pusher pump on the frame rail ...or could be an IDM ... or could be something elseSMITTY wrote:My neighbor's 7.3 just went away on a flatbed yesterday.

I hear you Berlin - guess I'll find out eventually. I'm curious now.
Sounded like pump was working ... but I don't have a reference as to how they're "supposed" to sound ..... sounded ok to me. Who knows ...
His is a '00 .... that infamous year again ....

I don't know if the 7.3 is the same as the 6.0 but, if the HP oil pump quits it will not fire the injectors and it sounds like it's running out of fuel. I know someone that replaced 3 HP pumps and sold the truck and it was less than 2 yrs old.
I've never heard of an HPOP failure on a 7.3, but yes, if that dies then everything stops. It's much more likely to be valve cover harnesses, cps, IDM, ipr or icp, possibly pedel or perhaps fuel pump.crazy4coal wrote:I don't know if the 7.3 is the same as the 6.0 but, if the HP oil pump quits it will not fire the injectors and it sounds like it's running out of fuel.

Just replaced the 3rd or 4th cam sensor on my 2000 7.3l F250 SD. I carry a spare in the glove box.
Then after clearing the codes, I noticed the tranny range sensor throwing a code. So that was replaced as well. A little rough to get off due to the steel shift shaft being corroded like hell. I just ended up busting it off. Plastic sleeve on that shaft so no biggie.
Found out the reason for the code, 1 of the terminals corroded or burnt off in the harness connector.
Knock on wood, I really haven't had a bunch of issues in almost 200k miles.
