Okay so ive driven the truck a little more, tested the lift pumo its working fine. Now im thinking the culprit is the fsd only because its still got the stock fsd in the stock spot, also read that a small fuel leak can cause this, can I please get some input?
Again the truck will run fine when first started in the morning, once warmed up it will either start stumbling and die or just stumble a little until you shut it off. Once you shut it off and restart it if it sits there for a few seconds or you put it in gear it will die and not want to start for a while.. ive been reading like crazy before I buy parts. Really want to exhaust the simple to do stuff first.
