Need Injetion Pump Help

[jayhawktrailers.com]

OK GUYS I REALLY NEED SOME HELP. I HAVE A 4BT WITH A WEIRD PROBLEM. THE ENGINE WAS GONE THROUGH AT A DIESEL SHOP AND NEVER PAID FOR. I BOUGHT THE WHOLE DELIVERY VAN, JUST FOR THE 4BT. THE SHOP WANTS ME TO PAY TO HAVE THE PUMP GONE THROUGH. I CAN GET IT TO START ON 3 CYLINDERS, BUT WHEN I TIGHTEN DOWN THE 4TH INJECTION LINE IT DIES. IT ALSO DIES WHEN I TRY TO GIVE IT SOME THROTTLE. MY FIRST THOUGHT WAS A STUCK INJECTOR ( ALL INJECTORS ARE NEW) SO I PUT AN OLD ONE IN. SAME THING. I'VE TURNED THE PUMP UP AND DOWN TRYING TO SEE IF IT'S A TIMING THING. COULD THE PUMP BE OFF TIME BY A TOOTH OR TWO AT THE GEAR? ARE THERE TIMING MARKS TO LOOK FOR? I THINK THAT I MAY HAVE A BAD PUMP, I JUST WANTED SEE IF THERE ARE SOME SIMPLE THINGS TO TRY, BEFORE I DROP ALOT OF MONEY ON A REBUILD. THE PUMP IS A ROTARY. HERE ARE THE NUMBERS OFF THE MOTOR

CPL 0858 ENGINE 44368760 INJECTOR 3912468 REF S064931



THANKS AGAIN

When it starts on 3 cylinders, does it smoke ? If so what color ? When you crank the engine over with all the inj lines lose, do you get fuel out of all 4 lines ?

I very much think that the lines are on the rong cylenders but it could be early or late timing. the thing is if three cylrnders run with bad timing the forth one should to.

THANKS FOR THE REPLY. IT DOES SMOKE WHITE AND WITH QUITE A BIT OF SMOKE. I NEVER THOUGHT THAT THE LINES COULD BE GOING TO THE WRONG CYLINDERS. I WILL GO LOOK AT A CASE SKID STEER AND SEE IF THEY ARE IN THE RIGHT PLACE. FUEL DOES COME OUT OF ALL LINES. THEY SEEM IN THE RIGHT PLACE

LOOKING FROM THE BACK OF THE PUMP

TOP LEFT GOES TO 3RD CYLINDER FROM THE FRONT FIRING ORDER 4 I THINK

TOP RIGHT GOES TO 1ST CYLINDER FRING ORDER 1 I THINK

BOTTOM LEFT GOES TO 4ND CYLINDER FIRING ORDER 2 I THINK

BOTTOM RIGHT GOES TO 2ND CYLINDER FIRING ORDER 3 I THINK



SORRY IF THAT WAS CONFUSING I WASN'T EXACTLY SURE HOW THE FIRING ORDER WORKED



THANKS AGAIN MERRY CHRISTMAS HOPE SANTA BRINGS YOUR TRUCK SOMETHING TO
