1997 K1500 ECSB L56 6.5 TD Auto F44 208k
Truck is a 97 K1500 L56 6.5 Auto with 208k miles on it. It had sat for 2 years before I picked it up. Previous owner didn't have the starter braced and using a Napa brand starter it broke off the bolts. But before this he spent $3000 with a new fuel pump (I'm guessing lift pump, idk if these have one in the tank), injection pump, and fuel lines. The truck does look taken care of and now that I've fixed the brakes and put on a new vacuum pump it starts and runs pretty well cold but once I get where I'm going and shut it off all bets are off. When it gets up to operating temp it seems like it doesn't want to run. It'll surge and try to stall under anything more than light throttle. Under load it'll start bucking real bad like a dead miss then it'll shut off and it is almost impossible to restart. I haven't tried rebleeding the system since I first got it and it seems to have a random leak coming from up by the tank but it doesn't leak when running or priming just randomly when it sits.
- Any help is appreciated, very new to this setup and just want it to run.
