2005 6.0 No Start this A.M.
Three weeks ago CEL code was low voltage to #7, cleared it, one week later CEL again code was low voltage to all 8 injectors. Truck never missed, smoked, spudered or lacked power. Last Thursday morning it cranked up but was loping and would not accelerate, let it warm up for 2 or 3 mins. then it ran like a camp. No CEL since the monday before. Started fine everyday since until today, no start. The only thing that was the same both mornings was the temperture. I live in Texas so summer is still here but this A.M. and the other day temps were mid 50 in the A.M.. Rmp gauge was working during cranking. Cranked at it 10-15 min on and off this A.M. battery were still hot.
Also have a 1999 7.3 (350,000k) which does the same thing, just thought it was old and tired, but it sounds like the same problem. Help me fix the 2005 6.0 and maybe I can dust off the 1999 7.3 and fix it also. thanks scott
