Engine Mechanical problem
1995 Dodge Ram V8 Two Wheel Drive Manual 150000 miles
The truck is a 95 Dodge Ram 3500 Diesel
I had been having trouble with the truck starting. I was pretty sure it was not starting because the o-ring in the fuel filter was broken, so I changed the fuel filter, loosened the bleeding nut, and then pumped the primer bulb about 80 times. I normally stick to around 35-40 times, but it continued foaming out. After that time, I tightened the nut, and then tried to crank the truck. It took a minute to start and ran for about a minute, but would never fully wind out when I tried to rev it up. It has a new fuel pump (within last 5k miles) and new filter. I'm not sure if the injectors may be clogged, a hole in the fuel line, pump relay/fuse/air near the injectors, etc. Please advise.
