any help would be greatly appreciated,I just did injectors on my 02 duramax. It frigin ran before, It ran like shit but it ran. Replaced the cmp and still no fire. I found a broken wire @ the plug on top of the engine, it was the hot wire to the cmp. I checked the wires @ the plug to the cmp getting 11.2 volts,the ground was good,no power to the signal wire. Found out that the signal voltage is shared with other sensors so I just robbed signal power from another sensor. Still no fire and it keeps throwing camsensor circuit code p0340. This truck is really pissing me off If it was a D8 I would have it running by now
