I just got back from a friends wedding and for the first time I was not embarrassed from having to try a couple of times to get the engine started.

The car, (91' 420SEL), always gets attention as it looks very presidential, that is why I drive it to social events, and now that it starts I will be driving it more often.

If you have a MB with a cold start injector, that in some conditions is reluctant to fire up on the first crank, I highly recommend using the cold start injector for every start. (providing everything else is working correctly in the fuel system).

Right now I am pulsing the injector for 1 to 1.5 seconds while cranking. If you have the means to build a timed injector driver it will be well worth the effort. The connectors for the fuel injector are pricey but they allow access to the injector circuit without hacking into the wiring harness.

I am kicking myself for mot doing this sooner!!
