F250 6.0 2003, Truck has 236,000 miles. Noticed loss of power topping a hill at 70 mph or so, next smaller hill, wouldn't make it up hill, but would still idle, but not rev up past idle, then died, no start. Buddy pulled me home, starts next morning when cold, only revs to 1000 or so, idles a bit, then dies, then no start. No start now, but seems to want to, with some cranking it gets to a sort of higher than usual cranking speed no start, sounds like a cylinder or two are hitting, but still no start.
Oil looks good, it was changed 2,000 miles ago.
Replaced fuel filters (I was a little past due, but not much).
Replaced air filter.
All injectors were replaced at 200,000. miles.
Checked fuel flow to top filter - good flow, no air or water visible in fuel.
Suspected pump, but pump running sounds normal.
Checked fuel pressure at top test port and got 48 psi.
It's not setting a check engine light, I don't have a scanner to look for codes.
I appreciate the great no-start writeup sticky, but was wondering if, based on description of problem, someone here might have some advice on what would be good to check next?
I don't have any diesel repair experience, but do have lots of other maintenance experience.
I don't have a scanner (as mentioned) or any special tools for this truck. Do Have a Fluke 77 and am proficient with it.
Any suggestions? Should I send it on to the shop? Buy a scanner? (Anyone rent those? (Questionable whether I can afford to send to shop, but I also can't really afford to be without the truck for any extended period either, too much work to do to stay afloat!).
Thanks for any help.
