Jetta 4 1.9 tdi

Post by Mozart » Thu Oct 10, 2019 11:02 pm

Hi there,

Please guys I really need your help.

My 2002 Jetta 4 1.9 tdi sprung a leak by the diesel pump, so I change all seals and placed the pump back in, did the timing and bled the system to remove all air. Now the car just swings and refuses to start.

Any ideas?

When a car tailgates me, i slow down - then floor it and give them a cloud of diesel smoke to choke on :driving:

is it delivering fuel. Many people has broken a pump by not following the vw recommended procedure by removing the pump and working with it upright rather than trying to o it in place.
If there is fuel delivered then you have a timing or a firing order issue.

Yes pump was removed and seals replaced,
Timing was set to tdc, pump timing was set too
After priming pump and cranking a few times, diesel is coming to injectors.

Maybe I am missing something, maybe you can explain the timing setting so I can double check to make sure it is all correct and try again

Crank tdc is set from the hole in the gearbox to the flywheel.

Cam tdc needs a locking tool.

Pump timing is locked with a 6mm (I think) pin.

Explained very easily in the above link.
