Isnt that what's used to time db2's? I'm using the ds4 because I couldn't get the db2 to push fuel.

 

yup, that's for a DB2.

DS4 obd I:

FYI: TDCO - Timing the DS4 Injection Pump

 

oops read it wrong i thought you swapped to DB2 not DS4 my bad

 

update, i got the full program from engh motors. i tried to do that ehole procedure but its still throwing cylinder balance faults and now i got a code 88 offset error.
desired timing 7
actual timing 7.1
tdco -2.02

what am i doing wrong?

 

not to sound dumb, but i thought the timing is 3.5?

 

i went back and read that how to again and it is suppost to be ~3.5. i tried to turn the pump but its at its limit. i took the timing cover off thinking the gear moved when i was changing pumps but the gears are lined up. possible that key sheared in crank?

ok so all the gears are good and no keys were sheared. guess ill put it all back together and see if maybe i put the injection lines on wrong or something. im at a loss as whats wrong with this thing.

 

Well, the timing is maxed out for sure.

Are you turning the pump in the right direction for base timing adjustments?

Turn to the passenger side is retard , turn to the drivers side is advance.

 

i got the timing down to around 3.5-4. tdco set at 1.5 so my code 88 went away. which way do i need to move the pump to get tdco to set a negative value? and im still getting cylinder balance faults and it wont rev and runs rough.

 

Negative tdco is to the drivers side....
