I am new to this forum as I just signed up about a minute ago.
I have a 1992 Ford F-250 w/5.8L.
It has no power at all. My brother and I gave it a tune up which included new plugs, wires, cap, rotor, oil filter and an oil change. Added Lucas oil stabilizer too just to be safe.
No of this fixed the problem! I am at a loss.
Clogged CAT? out of timing? Clogged fuel filter? NO pressure on the fuel pump?
I have not done a compression test.
In P (park) the engine will rev up like normal. When in D(drive the truck will just barely move. I am talking like 1 inch.
Any help or point in the right direction will be greatly appreciated.
