Got an email yesterday from Bluesmoke yesterday having some issues:

having A PROBLEM WITH MY 7.3L DIESEL IT IS LIKE MY FUEL PUMP RUNS ALL THE TIME NEVER GETTING THE LOWER SECONDARY VOLTAGE IDLES ROUGH TRUCK DIES IF I PULL THE FUSE ON THE FUEL PUMP SMOOTHES RIGHT OUT RUNS PERFECT ANY IDEAS

I then got in touch with Scuffy and he replied with:

would need to know a little more info , but in my opinion, an injector is feeding compression back thru internally , that will be a hard one to diag , the last one i had ran great with the drain valve open , similiar to shutting the pump off , ended up putting 8 injectors in it

And then another email this morning from Bluesmoke:

hello i was e-mailing you yesterday and was wondering if you could continue to help? I have been going threw my electrical system as i was saying about pulling pump fuse truck runs great. well it seems that circuit is being back feed because with the fused pulled i still have current on each leg of the fuse box? any ideas would be greatly appreciated

The truck is a 99 7.3.... you all know I'm no tech so any help on this would be greatly appreciated!!!

(He's a newbie and not sure how to post so I wanted to get this rolling for him!)

Hes right about one thing. If he still has current on both legs after the fuse is pulled he has a short somewhere. Have any accessories been tied in to the fuse box?

bluesmoke , you will have to trace this wiring to find the concern, thats the bad part about wiring no way to tell you where the short is
