After having the car sit overnight, I went out and cranked it first thing and it started up but immediatly the revs dropped off and it died. It started twice more for a few seconds (1 or 2) but I couldn't keep it running.
I bought a new fuel pump relay and replaced it but there is no change at all. It turns over just fine but it will not catch and start running. I can't hear anything from the fuel pump,but its dark outside so I'll wait till tomorrow and see if smacking the pump helps anything.
Zarf posted that I should check the crankcase sensor. Where is it and what should I be looking for ?
Also the MB parts guy said it can't be the ovp if the radio operates. Does this sound kinda fishy to you ? What are some indications that I can easily check to eliminate the ovp. According to some pictures posted on other threads mine has been replaced sometime in the past.

Thanks for the replies.
