alright, i hooked up my boss's computer/scanner to my truck and i got codes P0216:fuel injection pump timing failure...i cleared it and it went right back on, but no check engine lights?
i also got a code P1693: code detected in powertrain control module/companioni module/

can anyone help me out

 

that 216 is the code of death for the VP44. 1693 I believe is the failure code for the lift pump.

what kind of pressures are you seeing off your lift pump.

 

i have the FASS system so im @ 10-13psi constant never lower...so i guess that means i gotta get a new vp44 for sure?

 

Ok let me sort this out for you...

P0216 - Fuel Injection Pump Timing Failure High fuel supply restriction, low fuel pressure or possible wrong or incorrectly installed pump keyway.
P1693 - DTC Detected in PCM/ECM or DTC Detected in ECM A Companion DTC9 was set in both the ECM and PCM.

Basically 1693 is just telling you there is more errors in either PCM and/or ECM controllers thats all...
The 216 error means the advancement piston in the VP44 pump isn't working correctly any longer. The VP44 can no longer advance the timing as need. Normally seen in the morning there is a lot of white smoke from the lack of timing...

That should get you going again...

 

geez man thanks, your alot of help...the instructions cleared it up for me...

 

Not a problem that's what I'm here for...

 

so how do you bleed the fuel lines on thi motor? on the macks you use a lift pump, (hand primer) and pump till it get hard (pressure) and then crack open an injector line nut going into the head untill its straight fuel, no bubbles..then tighten it up...same for this truck ?

 

you hcan have the lines cracked and crank for a bit after you have replaced the injection pump just run the fass system for a bit to fill the filter housing and new vp pump if you are replacing then crank for a few till fuel is achieved at the injector jumper tubes.

 

Here is the process from the book...

Basically I would loosen the banjo bolt (#3 in Fig 2) and bump the starter. Left the fuel flow till the air is out then tighten the banjo bolt.

Then crack 1, 3, and 4 injector lines. Bump then starter again. Let the pump run to push some air out of the pump. Then try cranking the engine. When it starts to fire shut it down and tighten up the injectors line... Then start the engine... Leave it idle... DONT REV! let the pump clear itsself out of air. It will sound rather nasty and off beat...

 

yea i was just reading that on your site...thanks alot guys i just wasnt sure if i had to do any magic dance or anything different then a mack truck engine
