- Mercedes-Benz E-Class: Why Does My Car Turn Over but Wont Start?
Step by step instructions for do-it-yourself repairs
E320 won't turn over and rear electrical problems
My 2004 Mercedes E320 is sick
. She has at least two problems:(1) A few weeks ago I went hiking here in LA, got back to my car, and tried to start my car. The engine cranked but would not turn over. I cranked the engine a few times and finally it started. The check engine light came on. After that, the car would start fine and the light went out.
I experienced this same problem a few more times. I brought my car to the mechanic, and he said the battery was fine. Last week I went hiking again and the car would not turn over for anything. I called AAA, and the tech said the battery was fine, but it started once he jumped it. I replaced the battery, as it was getting old anyway.
Today I parked my car on the street and went into a restaurant. When I came out (with a brand new battery in), it wouldn't turn over. It finally did, and I went home.
I have seen a lot of talk on here about a "crankshaft position sensor." Does anyone think this might be the problem? How can I diagnose it? I plan to bring my car back to the mechanic soon.
(2) The second problem is that two of the lights went out on the rear of my car (one license plate light and one third brake light). The mechanic replaced them, and they were still out. Now the electronic trunk opener doesn't work. The mechanic thinks this is an electrical problem. Does anyone have the slightest clue what type of problem, lest the mechanic pull all the wires out to find out?
Any help anyone would have would be SO gratefully appreciated!!! I'm desperate at this point!
You would be well served to get any codes read by someone with a Star system for doing so. The dealer will have that, and some indies do as well. Otherwise, you may end up throwing parts at the problem unnecessarily.
As to the CPS issue-my recollection is that it manifests on a hot engine, and that one of the telling symptoms is that you let the car cool down and it starts right up. Yours sounds like the flip of that. Ergo-the recommendation to read codes, especially since your check engine light did in fact come on.

Thanks!
Also, 99.99% of the time, you don't need a Star reader as any OBDII reader will read codes just fine. I get mine read at local Autozone/Advance Auto Parts if I am in a hurry.
