Well I was on my way home from work which is 45 miles away and I was 3 miles away from my destination. I had previously drove it for about 400 miles before it just quit on me. I'd have to rule out timing b/c It started previously. Compression? maybe. I need to find a diesel compression gauge. I don't have one. And none of the autoparts stores do either. I know I am getting fuel to the IP b/c I have pulled the supply line to the IP and plenty of fuel comes out. I'm not sure how many miles are on the truck it says 158,*** but not sure if this is original or not. I got the truck from my father in-law. It was sitting for about 1yr with only being started 3-4 times withing the year of sitting. I went to his house to pick it up and it wouldn't start. So, I put a starter and new batteries in it and it started right up. He lives about 110 miles away. While on my way home I put some fuel in it. I drove it to work 3 days which is about a total of 270 miles and when I was 3 miles away from my house it died and has not started since.
158XXX miles is time for a replacement pump and injectors, but it shouldn't be worn out completely!! She should still start and run, but be a little sluggish.
It's possible that something has gummed up inside your pump, or maybe the internal timing advance on the inside got all out of whack while it was sitting all that time.
White smoke from the tailpipe means fuel IS making it to the cylinders.
The GP's should be glowing LONGER than 5 seconds. I would say you either have a few burned up, or the harness is corroded and not lighting off all 8. Be careful removing them (1/4" drive ratchet) so you don't twist them off. If they seem stuck, hammer them with pennetrating oil for a couple days and then try again....do't force them..they will break off in the head..then you gotta pull the head!!
Ony a cold morning, I've seen my plugs pop on for 25 seconds sometimes. Use ONLY motorcraft or Beru plugs....from either a Ford dealer or International dealer, or other parts stores...make sure they are Ford Motorcraft or Beru though! Others are known for not lasting or swelling up inside the head and breaking off.
These are easier than a gas engine to work on....you don't have to worry about getting spark. Just fuel delevered at the right time, compression and heat to make them work.
Test the GP's, disable the few remaining ones and hit it with a sniff of white death...make sure the GP's are disabled though....could get interesting if they aren't.
