1997 Powerstroke no start, but turns over. PATS Issue??
A friend of mine has a 97 F-250 4X4 7.3 diesel Crew Cab that I sold them 3 years ago. A couple days ago they took off in it and it went about a 1/4 mile and died. They thought it might be the PATS system because the truck had been broken into a couple months ago and some wires messed with. The truck will turn over and the Tach moves, but has no oil pressure showing and no fuel going into the filter canister. I'm at a loss on what to do. I really hate taking it to the Ford dealer. I need to eliminate some things one at a time. How do I know the PATS isn't the issue? It was very low on oil, but I have filled it back up to the full mark. Please give me some idea what to look at first and maybe some kind of checklist to go thru.. Thanks!!!

As far as I know, OBS trucks didn't have PATS.
The fuel pump on the OBS 7.3 is manual from the factory. Unless it has been upgraded to electric, it should be pumping fuel if the engine is spinning.
Make sure fuel tank is above 1/4 tank. The showerhead pickup tube in the tanks rot off and then you can't pick up fuel if it is below that amount.
I don't have a link to the no start flow chart, but I will look for it.

Thanks Kevin, the truck has a PATS, "Passive Anti Theft System" on it under the dash and it has cause me issues before. I thought the 97 was like all my other trucks, 99, 2001 & 02 and had an eiectronic fuel pump. I will check tomorrow for fuel flow while cranking the truck over. Both fuel tanks are full, so the pick up bell isn't an issue.

OK, we finally got it running by resetting the PATS system several times and had to do it a few more times in the last 2 weeks. I need to find a way to remove the PATS system completely. Does anyone have a good wiring schematic that I can look at to see what wires need to be paired up to bypass the system?
