You already have it. It uses a doppler sensor to detect the flow pulse.

Can It get out of time if

My 220d timing chain skipped a tooth on the cam sprocket might have been 2 teeth I retimed the cam by moving the chain on the gear it is now right 0 degrees of chain stretch but the car will hardly start wont idle has no power under 3 K RPM I am going under the assumption that the IP needs to be timed now maybe even removed and put back on so the alignment marks are correct Is this logical or am I chasing my tail.

Also, how do you get the fuel to come out the tube for the drip method? Do you pump the primer to get fuel flow out the tube? It doesn't seem like you guys do this with the car running. Then if the flow isn't what it should be at (24BTDC?), then you adjust the IP and pump some more?
Thanks
David

mattdave, you probably need to retime your IP, likely pull out enough to decouple the splined drive and reinstall. A good engine with bad IP timing will behave just as you describe. Don't ask how I know this.

I'm personally a fan of the bubble method. I personally think its easier than the drip method and gives better results for me. Below is a write up that I copied from Marshall Booth over on the Mbz.org mailing list (he's a member here too, though not so active here).
-----------
On the subject of diesel timing. If you are replacing the pump or rebuilding the engine. The simplest and most accurate way of setting the pump is: Disconnect the fuel line going into the pump from the filter. Take the spring and plunger out of #1 delivery valve, put the delivery valve back in and snug it down, hold the the pump linkage in the full open position. If you have the drip tube install it on the delivery valve, if not use the injector line in such a way that it is pointing away from the engine. It you don't mind the taste of diesel you can blow through the fuel line or use low air pressure. Put the open end of the injector line in a glass of water and watch the bubbles. Turn the engine slowly until the bubbles stop and check the timing mark. After tightening the pump recheck. This method is really more precise than it needs to be and although it may sound complicated it is very easy .

(Edit for even worse than usual grammar)

I wish somebody provided pictures as the "bubble method" seems interesting.
