Well, Installed the NEW pump unit today. All is well. For reasons I do not fathom, the engine now starts without hesitation. I have no idea of the connection but it usually took a few turns to fire. Now it is instantaneous.


Hardest part of the project was getting all the interior parts back in. The guys who installed the new headliner had broken a lot of the clips. New ones were $5 apiece so I cheated and used the closest cheap ones on the shelf/rack.


I did remove the rubber plug in the well as many Have done. Put the pump inside the foam and covered that with a poly bag Loosely wire tied around the wire and hose bundle before I closed up the compartment.


And now ALL the lights function as designed.


Speaking of design, why in the hell did Diamler design something which is inherently subject to failure? Surrounding a circuit board with a sponge and placing it in the bottom of a well where any leaks or spill would go. And then, calling it, hell giving it the function of a "Security Module" German engineering is usually superb.


However, I must remember that Germans once built big dirigibles and filled them with explosive gas. Flying through clouds, and operating electric appliances aboard, what were the odds of a spark?
