Have a 1993 7.3 idi (non turbo). I bought the pick up recently, ran pretty well when I first got it, started having some problems with it, some I have worked out but I think I’m still having a serious fuel delivery problem. These two forums pretty accurately describe what’s going on with it.
I do not think I am having a problem with the alternator as it seems pretty new, pick up also religiously starts every time besides after dying on me while driving ( I’ll have to wait a while to get it going again or crank on it a good bit while pushing ******* accelerator) batteries are also in good condition beside some corroding grounds but I’m keeping those clean and greased(have new cables on the way). I also changed the fuel injectors, glow plugs, and fuel filter. I filled the fuel filter with opti lube XPD (lubricating fuel additive) let it run a bit, and then sit overnight in the hopes that this would clean up my injection pump and fix the problem. The next day it did run a lot better and I was able to drive it around as long as I kept a close eye on rpms, if I did not sometimes it would die particularly while up shifting into 3rd or 4th. Today the problem is back with a vengeance and I can barely make it around the neighborhood, tried and it died on me several times, once even going into second. Even if I can get it to shift a lot of the time it would slowly lose power and get really quiet, by pushing on the accelerator all the way it starts to catch up and maintains speed but especially in third it will do some weird things, sounds like I’m letting on and off the throttle but I’m not I think it’s just failing to get fuel.
I do have a fuel leak from the front take, I have only been running it off the back tank till I can drop the front tank and find out what’s up with it.
Apologize for the length of this I’d just like to get some solid advice and give all the necessary info for that. Am I incorrect in assuming this is the injection pump? If I am correct that it is the injection pump would you recommend going through moose diesel to get my rebuild done? Lastly, it does not have a turbo or inter cooler but want to put one on one day does anyone know if I’d be able to run the junior moose on mine without causing serious problem to it? I did reach out to Moose Diesel today and am waiting on a call back from them.
Thanks for answering my questions in the past y’all were a huge help.
