Ok he we go. Got a 93 ctd w/ 218k. lost the first pmp @ 130k Rebuilt it and lasted til 212k. This time aound life changed and due to time and $ opted for a pulled pump. My mech that did the swap is good and honest but not a diesel guru.(again no time to do this job my self). Now the old battleship is slow to start (use to is firing up in less than the turn of the key even in the dead of winter).The beast is gray smoking hard when idling( even at red lights), plus I have little power( acting as though it is starving for fuel). plus on a road runs it fighting for 75 mph in od. previously it would run all day long a 75 or 80 easy. My thought is that this pump came out of a 94-96 ctd that ran a pistion lift pump (higher psi and volume than the older diapham). the only disernable numbers on the tag is (x9712) the rest is a wash. I want to know if my thoughts are on track or am I running on a dieing pump and thus need to expidit the rebuild of the original pump.

 

94-97 run a p-pump.Is it still a rotary?

 

I bet you have a timing problem.

 

agreed

 

no its an inline

 

i think hes trying to ask if it is indeed a p pump or still a rotary pump. he could be saying that his lift pump alone is out of a 94-97.

 

Or, did you swap the injection pump to the p-pump and not swap the lift pump to the higher pressure one?

 

its a mystery!

 

Ok dudes, you all can smack me up side the head and give me a reset. I went tech head on this prob. vise my own phrase of K.I.S.S. ( keep it simple stupid). I did know about the timing marks on the pump but completly over thought it and did not even think to turn my lug head to the left and notice the whopping spread of an 8th of an inch differance (counter clockwise) between the idiot marks. Thus the pump isretarted right now and is late. Sorry for wasting everyones time on this oversight of mine. My appolagies.
