I understand where your going, and he did check the fuel pressure and its good... Thats why I am puzzled on why it isn't starting... Could it be that crank sensor?

yup.....it could.

So I guess I am going to drive down to the dealer tomorrow and pick up the crank sensor... I mean if that doesn't fix it, I will just take the part back... I am so frustrated with this car... all I want to do it get in it and drive it.

If they will take it back, sounds like a plan.

If you had a meter , you could just unplug it and see if it gives out a signal when the car cranks over...but changing it will tell too...

Most dealers will not accept return of an electrical part once it has been installed (and yes, they can tell). You will want to be fairly certain that you actually need the part.

the security system allows the engine to crank but the engine won't fire. ..did you at least do the excercise of making sure the security system is disabled

Are you sure about this? I've never engaged it on my W210 but on other cars I think I was not even able to crank when security was enabled???

hay have you checked the fuel injector pump beacause i had a problem liek that before with one of my other cars and that got it worken againbeacuse it would try to turn over but nothin would happem

Good day MB gurus, I have a 1993 300e-2.8 which I think has a similar engine with the subject car in this thread (am I correct?) if so, what values should I be looking for if I do this test on my car? I read in some thread 800 omhs, is this correct? Am I looking for voltage or continuity? Sorry for the newbie questions.

since its sunday and tomorrow's my only chance to buy the CPS, I want to spend some time with the car just to check if its got a bad one, though I have also read in some thread that the CPS can pass a test but still be bad, I am just hoping to confirm it if it does at all. I dont want to pass any chance I can get to make it run again as I miss the car sorely! (and the inlaws are getting agitated from my borrowing their car, they want me to just send the car to a shop to get it over with )

I can confirm based from experience that this can happen.

where the cps located on the 97 e320?

where is the cps located on 97 mercedes e320? need help fast!!!

I just bought 97 Mercedes e320. im trying to fix up. the guy I bought it from said someone ran a diagnostic and told him it had a burnt valve and needed new motor, hopefully this isn't correct, I have been tring to crank but it sounds like fuel isn't getting to the injectors. I am missing owners manual and fuse chart for all 3 areas,

the car is sitting off balance with the tire under fuel tank all the way flat, I have added premium from gas can and fuel is reaeding low in cluster, I was wondering if sending unit reading could be inaccurate due to imbalance from tire,

also I put battery in and something is draining it , when im not trying to crank, I was wondering if the car phone could be doing this and what to do?

thankyou any help is greatly appreciated

The fuel tank on these cars is in the trunk just behind the rear seat back not under the car. The fuel pump / filter is under the car, just in front of the left rear wheel ( there is a plastic cover over the pump / filter ) .

A burnt valve won't keep the engine from running. Did they say what cylinder has the burnt valve? If not they are probably just guessing.

We need more information, what is the history for the past year of this car?

First, after being in, on and around this forum for some time, it has become apparent that technical/engineering/mechanical skills of forum members varies greatly. That said, after having my cars to many, many different indy shops, I've come to realize that the same concept holds for both indy and dealership mechanics/techs. Read the following thread carefully, notice how the dealership was close to solving his "no start" problem but in the end, it was a friend with encyclopedic knowledge of the W210 that saved the day.

Perhaps his friend could offer consulting services to the dealership on an hourly rate, no?
