So I bought a 2nd gen, had high miles on it and could tell had been sitting. Upon buying I started having troubles, after driving it home 6 hours away I started trying to get it back to 100%. Narrowed down the first job to being bad injection pump, so I bought a new one and replaced it. Seemed to have fixed the issue and was running good, the truck doesn’t get driven daily it’s my farm truck, I started driving it a lot in the last month and when driving the truck is fueling really weird.
#1. It does have hard start after sitting over night. After that starts fine all day.
#2. When driving and maintaining speed say 1700 rpm you hear the turbo and feel the truck speed up itself and slow right back down.
#3. It does it more “aggressively” when engine is first started and I start going somewhere seems to get better as I drive.
#4. I noticed what appears to be diesel dripping around back of engine, I’ve checked the banjo bolt and T fitting doesn’t seem to be saturated at all and all seem right.
Im getting directed to new injectors and crossover tubes the truck is a 2001 HO 6speed with 270k showing on it. Was completely stock when I got it except raptor lift pump and a welding bed on it. I have searched and can’t find any thread similar, most describe a miss or surge and mine speeds itself up and slows back down. Any advice would be appreciated.
