1st diesel problem less than 48 hours of owning it!!!

[Just A Good Ol Boy]

Was going to post in the 7.3 tech/help section but got a window saying I wasn't allowed. Anyhow.

This 00 7.3 I just got yesterday. Its giving trouble already! Hoping you guys might lend some insight for me.

Symptoms are:
After driving it and getting engine warm then shutting it down, then about 15-30 mins later get in go for a ride. Sounds like an injector is clacking louder than usual. Runs rough like a gas burner with a burnt spark plug/missing. Ive been able to give it some throttle and it straighten up after a few seconds. But tonight I was out cranked it after setting maybe 15 mins. It starts running so rough and lack of power it shuts off. I tried to start it again and it would die. Finally I got it to run enough to get it back on the road and after a mile or so it straightened up and I got it back home.

There is no CEL on so no DTC's and yeah the CEL light does work.

My friend who is a ford diesel tech says that he thinks its a screen for the pickup in the fuel tank thats causeing this. What do you guys think? And where can I get these sending units or replacement screens?

I can't help you with your problems, but here's a bump so one of the techs will be more likely to see this thread.

Thanks for the bump.

even without a cel there could be some codes stored. did you try and pull any codes. sounds like it could be the wiring that goes through the valve cover

Yes, a soft code wont trip the cel. You need to get it scanned for codes

I’m from Lacey’s Spring but now live in Priceville and used to work in Albertville and Boaz years ago.
Anyways, hard start or no start when hot is indicative of IPR problems, usually bad O-rings. I have a spare IPR you could borrow and try, also o-ring kits are available fairly cheap.

Yes there is a screen in the tank but I would not replace it, I would chunk it, not one of Fords better ideas. Not only will the screen stop up if you get a bad load of fuel, it also causes air to get into the system which is bad for injectors. I highly recommend doing the in tank and prepump filter mods. Total cost was about $35 and it made a big difference in my truck, even my wife could hear the difference. Also it helps prevent catastrophic problems from a bad load of fuel.

If you need any help doing any mods or working on your truck let me know, we don’t live that far apart and I enjoy working on and learning about the 7.3, There are very few parts on my truck that I haven’t had to replace over the years, motor had to be rebuilt at 205K, tranny at 198K, torque converter at 135K, rearend at 230K, etc etc..

Sending you a PM frog.

Check to make sure all the connections are good a the VC's, and you might wanna get the CPS replaced. That screen thing makes sense too in the fuel tank!

I got oasis and as built and warranty info last night from FMCDEALER (ford technician site). The CPS was replaced, but I have not checked to see if its the grey one or not.
Gonna run up to Advance Auto and get it scanned they say they should be able to scan it.
I gotta figure out what it is pretty quick. I called the lot I bought it from and they said "if something were to go wrong right away we would fix it" so Im rushing to figure it out. If its only the intank and pre pump mod then maybe I can do that if frog can hook me up.

How'd you contain the shavings from cutting the filler and vent tubes? What were those pieces you added and deleted, frog?
