Hi all, my 2000 C280 is not starting and I need advice / help on the diagnosis and repair. IT will run but not restart. If I wait anywhere between 5 - 15 min the car will start and run between 2 minutes and 1 hour. I am considering the fuel pump and filter but these were replaced 11/07. I have my doubts that this could be the problem but I wont completely rule it out.
Is it unusual for a fuel pump to die in 12 months? I would like to check the system out. Where do you test for fuel pressure on these cars? Also could this be the Crank position sensor or is that a different set of symptoms ? I am looking for advice / procedures or other related devices that could cause this. Currently I have pulled the codes with a hand scanner and there is nothing stored or reported in the system.

Please advise

Thank you in advance

I'd suggest replacing the CPS. Pretty common failure; gets hot, stops working engine dies. Cools off, works again engine starts.

Thanks, Where is this part located as I do not have any manuals for this car.

It'll usually be on top of the trans bell housing on the drivers side. Some models you can get there from the top, others only from below.

It can be tested with a meter. Cant remember the procedure but search should find it.

Yes, sounds like the faulty crankshaft position sensor (CPS) that I had. The random no start progressed to sudden stall syndrome (SSS). You need small hands and an E8 torx socket. On the tranny bell housing by the firewall, drivers side, from above. Take a look at the part at Fastlane, there are two types with different clip attachments.
