606 IP Calibration - PeachParts Mercedes-Benz Forum

I initially started a R&R of all fuel lines and o-rings, to include o-rings and crush washer in the IP on my 96 E300D. I did manage to get her dry from fuel leakage. In my continued efforts to solve a mis on one cylinder, I further removed the fuel delivery valve in the IP for that cylinder.(mistake) I'm unable to get the engine to restart. I regret to admit defeat, but believe that I may need to remove the pump and send for calibration. How much should I expect to spend for calibrating the pump and where might be the best for this Bosh pump 0 400 196 002

Regardless of what you did, if you only disturbed one DV then I doubt the car isn't starting because of that. I suspect you have it air bound and need to purge the air from it again. The car will start and run on 4 or 5 cylinders so being without one would not prevent it from starting. I would not give up on it yet...you ought to be able to get it running again if all you did was disturb one DV.

Look for air in any of the fuel lines and if present resolve that first.

A healthy shot or two of WD40 in one or the other ends of the crossover pipe (not upstream of the maf) would tell you if it will run.

Since checking the GP's is so easy you should probably confirm they are working too.

You could also crack the fuel line at DV#1 and see if any fuel is present when cranking too; but only after confirming all air is out of the system and all lines are full of fuel. Before pulling th pump you should re-do DV#1 and torque to 35Nm after confriming all the pieces and parts are installed correctly. There was another fellow here not long ago sho jumped the gun and pulled his head only to find he had pinched an oring when doing DV's the month before.Got no fuel to that inj.

Be patient. It literally took me a couple days (granted it was only a couple hours a day) to purge the air from the system after I changed the O-rings. The routine was:

Crank for 10-15 sec., wait 30, repeat until battery is dead, charge over night and try again the next day.

The engine did not even sputter until the second day of trying. I probably didn't do something right during the replacement process and that was the result.
