My 1997 Mercedes E320 has been down and out for the past couple weeks. I have had it to a garage that keeps telling me its a relay fuse which they can't find. Someone else on here told me it was a crank sensor... Which I drive an hour to the dealership today and picked up only to get home and that still hasn't worked. I have spent well over a thousand dollars on this car trying to get it started. It has 190k miles on it now... The fuel filters are new, the pressure is good in the lines and the fuel pump is new... but still the car wont start... It cranks and cranks and still no start. Please help me!

You were not told it was the CPS...you were told it was a possible..and I told you to test the old one BEFORE trowing more parts at it ..

I also told you to check the FP system and you didn't know where the test port was ..your answer was it was fine..well, if it is fine , tell me what the pressures were , both with reg/vac on and w/reg/ no vac.
You want answers,but we need info.
Go back to your last posting and you will see several people have tried to help you..
What were the results of the FP test...??? " it's fine " doesn't cut it... I mean what were the FP specs you found???
If your guy changed the FP, I have a feeling you have a fuel problem.

And if the guy can't find the k-40 relay, he does not work on benz
