| P1093, U1000 Codes & description of problem
Stock 2002 6.6 duramax:
First start of the day, every day, starts quick, easily and without a hitch. Every other start during the day seems to take forever sometimes not starting at all. Once started the truck runs perfectly no hesitation, studder, anything.
New fuel filter & batteries checked good under a load test. Also dealer checked the injectors, said to be doing great.
Have two current engine codes but no engine light.. wtf?
P1093 - Fuel rail pressure low during power enrichment??
U1000 - Loss of communication?? -> with what from what to what??
Its stock so it shouldn't be running out of fuel should it? Also like I said, it runs great, even under wot.
