97 F250 PSD help

Ole reliable is finally beginning to act a little strange. Last week one morning (outside temp around 40*) my truck started ok but,as I was starting up the highway,it started losing power(not missing)like the fuel filter was plugging. I pulled over and finally got it to rev up above 2500rpm. Limped it back to my shop and pulled the fuel filter.(it only had 5k mi.on it). Installed new one and it was fine the rest of the day.This morning I drove it to work and all was fine until this evening it did the same thing. I was in town and was lucky to make it off the street. I finally got it to rev up again and it ran fine the rest of the way back home. Could it be the wiring harness under the valve covers going bad? (still not missing)
only has 172k mi.

My 1996 did the same thing.Replaced valve cover gaskets under valve cover harnes.Out side valve cover gasket harness..It felt like it was running out of fuel...

Put a cam sensor in it, takes $20 and 5 minutes.

if it started running like it was on 4 cyls with ot wo a cel its most likely the inj harnesses burnt, very common.

Never noticed it actually missing,just not wanting to rev and smoked when trying to accelerate.
seemed it got better as the engine warmed up.
Is there a FUEL heater somewhere near the fuel filter area on this year/model?

fill a styrofoam cup w fuel, if it melts within a few minutes its got gas in it, also if its not crystal clear....... cloundy looking there is water in it. check oil level also.

When I changed the filter it looked clean and no sign of water but,that doesn't always mean anything. No gas in it.

Rick,
Just scrap the truck! You put your poor wife back to work and you been making money hand over fist scraping cars I figure you just call up Lem and order a new one!
And no I can't afford to borrow you any money.

It has a butterfly valve in the turbine outlet to the exhaust, I wonder if the butterfly is sticking shut, they wont rev or smoke with it stuck shut.

If I had your money I would I would do exactly that. Hell,you have a race car for everyday of the week. And also,that Pic of the galaxie in the avatar is Kickass brother.


Blake,I will call you later.

Possible restricted sock in tanks or tanks or fuel pump getting weak under the intake....fuel pressure gauge will be your friend......does the engine sound like its "cackling" before it dies?

that year does not use an in tank sock, a fp test will be your next step if the oil level is full.

I have seen the switching valves become an issue.

Must be repaired

Mine started acting very similar last week, (gas engine though). Coming home on the highway it felt like I was fighting a brick wall the whole trip, bucked hard if it got over 3k but revved fine when parked. Hope you figure it out, and I hope I can figure mine out too

Haven't had chance to do any testing yet. This morning I will check oil first.Only 5k on the change and it usually doesn't burn any ,but we'll see.Then check the flap in the turbine outlet to see if it is working correctly. Then just go from there. Thx for all the help guy's

Think the problem is solved,it was low on oil. Thx Jon
