Some of yall may remember me posting about my truck just not running right.  Biggest thing was no HP and lugging when letting out the clutch. No codes no exact anything really, so one day I had my friend come over with his scanner. We ran through all history and codes(this has been done no telling how many times and never caught it) and injector function when we finally noticed the inj pump voltage was 11.2 and we both not knowing for sure but thought this should be at least 12 volt. So I call Moparman and he said to change out fuse for inj pump, and there it was voltage jumped 12.6 truck noticeable running better. So we ohm the fuse because it looked fine, 0.002  to  0.018 just kinda jumping around. Needless to say she has all new fuse now and working on replacing all relays. These fuses have been in the truck since 2001 and sooner or later everything gets tired. Oh symptoms were eng. would die for a split second and run again. It would go as long as 2 months and never do it again, when I parked it it did it 50 times in 20 miles. Replace them fuses fellas. 

Which fuse did you change?

Inj pump fuse, I think its the second fuse up from the bottom left. Its the rectangle fuses. But somebody should chime in soon that knows.

Hey thanks for the update. Glad it turned out to be be easy and cheap. Strange how they can go bad like that.
