Injection Pump Problems
 

Can anybody tell me why #8,6,5 injectors are not getting any fuel but the rest of them are? I pulled the lines at the Injection pump and all are pushing fuel but those 3. Has the pump gone bad and if it has, why? Ive only had this pump a year and a half

got me on that one.....

drit in the pump clogging them 3 maybe pull the filter off and drain it put some Power service and fire up for few mins then shut it let it sit over night and the see if get fuel

Has the engine sat for some time and not been started or has it been cold and you have water in fuel? Im thinking you have a couple discharge fittings plugged. It is the only thing that would not allow fuel out of certain lines. All fuel is moved through these pumps by a vane pump for the low pressure side and then a cam with two pistons for the high pressure side then distibuted through the head .

Can any one help me out my 93 cummins has a couple problems and i need help one of them is when im in drive and at a stop sign or stop light it feels like it is pulling but it only happens sometimes? i really need help. thanks.
