The chevy dealer set the timing on the pump after it was changed out. I do not know what it is set at. I am pretty sure the OS is still plugged in, I will recheck the connection. Would a bad OS cause no fuel at the injectors? The engine will crank but not start and I get no fuel at the injectors...
Put on new injection pump, truck ran for a week then quit running while driving and then would not start again. I just checked for diagnostic codes and got a 17,18, and 84. I have seen some sites that say 17 and 18 are Crank Position sensor faults, is this true? Would the CPS cause a no start...
