2003 6.0 NO START CODES p0263, p0266, p0269, p2290, p2291, p2617, p2623
 

Please HELP!!! My 2003 powerjoke 6.0 stalled the other day and will not start. I pulled codes p0263, p0266, p0269, p2290, p2291, p2617, p2623. I have fuel and can hear the pump running. Truck is completely stock. I need Ideas.

Thanks Ryan

Wow, that's a lot of codes. You have cylinder contribution/balance codes for cylinders 1, 2, and 3. You have two low ICP pressure codes and a crank positon sensor code. You have either a high pressure oil leak or a failed HP pump, or IPR valve. I haven't actually seen to many bad IPR valves so I would lean toward the HP leak or HP pump. Another possibility is no base oil pressure. Better tow it to a dealer.

I saw bowtiehatr and canada talking about having high multiple codes much like these.......I believe they said wiring harness, but I'm sure they'll be along shortly to comment.

i think you hit this nail on the head goose.

when me and canada were talking about harnesses the codes were for circuit low. contribution codes is skip or losing oil.

another idea is what kind of oil and weight are you using. had a few trucks that had the wrong weight for the climate they were in. also check the oil level, cause your icp could have puked oil and you could be low.

I knew you'd save my rearend Bowtiehatr--lol. SEE GUYS--best techs--period.

Ran 414.8hp 716tq on the dyno stock injectors, turbo and aircleaner--just a tune Matt did for me--lol. Not bad for a granny truck, huh?

sweet man, sweet.
