Possibly a faulty injector with a leak off circuit fault but have also had problems with fuel line o rings that have shrunk letting air in. Have a close look at the fuel lines when the engine is running for air bubbles- if air can get in then the fuel can run back to the tank.
If we get a cdi in nowadays with a fuel pressure/
starting fault we always start by replacing the
o rings even if there is no sign of air in the clear plastic lines- they only cost pennies &
never get changed until the car breaks down.

Hi Mike.
What is the rail pressure reading when you are cranking.
Does it fluctuate from a higher reading to lower whilst cranking?
What rail presssure do you have with the DRV connector detached.

Cheers, Tony.

rail pressure goes up and down ranging from 7 bar up to starting at around 120 bar.

replaced valve at rear of rail car starting better but now and then after first start cuts out restarts but you can tell when you start car that the engine is ticking over poorley like low pressure,cant get any seals for pipes say pipes come complete with the seals?

Hi Mike
Check fuel tank (saddle type ) easy to get to under rear seat one side of tank runs dry, relies on return to re fill it
Normaly happens when gauge shows quarter full

Hi Mike,
Yes the new pipes come with seals installed.
Most MB dealers keep these pipes in stock as they leak for a hobby. !!

Cheers, Tony.
