Throwing codes 56, 55, 65
To summarize for anyone else reading this post:
1995 f250 5.8l 2wd automatic w/ OD: Truck ran fine, then one day cranked and didn't start until third try. Couple days later it stalled going from reverse to drive. It started right back up and drove fine 30 miles home in stop and go heavy traffic. It was 102 outside in San Antonio and it ran a little warm, with the needle about 2/3 towards hot. But once we got moving again it cooled back to normal and it ran fine the whole trip.
Next day it quit on me 3 miles after I left the house. 80 degrees and engine just reaching normal operating temp. Engine died all of a sudden while cruising at 40 mph but all accessories still worked. Crank but no start. Got it towed home. After much research and help from the forum I figured it was a bad PIP sensor.
I got the old sensor out of the distributor but the teeth in the circular plate that's pressed to the shaft looked pretty boogered up like previous owner just smashed it back on. I went ahead and bought a new Spectra distributor with cap, rotor, and new pip already mounted from O'Reilly's for $90. I didn't want to worry about the old plate coming off, plus by the time I bought a new cap and rotor it would have been almost as much as the whole new unit.
Put in new distributor just now using old cap, wires, and plugs and it fired right up. No CEL. YES! Don't have a timing light so I used a vacuum gauge to get a good smooth idle at about 21." I got new wires and plugs, so I'll swap those later but I was curious to see how it would do with the old stuff. I'll get a timing light on it soon.
Thanks again to subford and everyone else who contributed and saved me from throwing parts and money at it!
