Hi Greg,
The actuator push rod went through (puncture) the clutch lever. The engine has started twice after the repair, but stalls after 3 seconds and never started again. The primary fuel pump works O.K. I have erased the stored code... and the engine still refuse to start. The voltage at the battery is 12.86 V.Thanks,Luc

No code. I have removed the transmission to check the flywheel positioning. I am quiet sure that I have aligned it according to the dowel pin... but as I have said before the engine was running before the clutch lever and the clutch replacement. Every electrical wiring and connection were checked out. The primary fuel pump seems O.K. So... what else could it be ? I have to clear this aspect out of my mind.
Thank you Greg, I know that it is very hard to help at distance. You do not know what kind of knowlage I have, you just rely on
my report to you.Luc

Okay try the following ,

Remove the air intake hose at the throttle body .

Soak a clean rag in petrol .

wring out the rag so its not dripping petrol and then hold

the rag over the intake and crank over the engine ,the fumes from the rag will make the engine start ,

as soon as it starts remove the rag .

If she starts then stalls check fuel delivery system.

Dear Greg,It is a Diesel... 450 CDI, there is no throtlle body. What means the P2256 for a Diesl (engine code) tha was stored. After code earasing, it never show again. I think that the engine has to run to register code ?
I have removed the flywheel assembly because I had a doubt... but everything was perfectly aligned.
I am about to finish the reassembly a try again. I will have a closer look after the electrical wiring and sensors.
Thanks again,Luc
Mercedes Mechanic: Greg, Technician replied 9 months ago

Luc i know its a diesel ,intake to the intake manifold is a similar TB .

But on the intake hold the rag.

Dear Greg,
Ihave found my problem... it was a wire that goes to the shutoff valve on the injection pump. It was damaged in the envelope cause by a little kink on it. Hard to see at first. This is when I check the continuity from all the electrical connection to the ECU, then BINGO... the engine come to life. You were partially right to make me look this side.
Again thank you for your help... sometime talking to another mechanic helps for the moral.Luc from Montreal
P.S. maybe I could soud funny sometime, I made my english speaking friends laugh of me. I'm a french canadian,
Mercedes Mechanic: Greg, Technician replied 9 months ago
