left on idle for an hour and it started to steam. no visible leaks. not overheating

car it ran for a min then just died and wont start back up it cranks but no fire plus my dash says 1 malfunction and 2 malfunction

Car does not start. Key turns on battery and all electronics work fine. Battery has been tested and is good. Car doesn't make a sound when key is turned to start. Car wouldn't switch gears with the battery on, until the battery was disconnected for ten minutes and reconnected. Is it the Starter? Solenoid? I heard something about a neutral safety switch...

I must refill water in coolant resivoire regularly is it a bad thermostat, just an eroded gasket around the houseing, a temp sensor or a water pump? Help

fuel pump and filter replaced by dealer noies stil comes and go's

I struggle when start sometimes motor sounds right and sometimes it sounds like two or three selinders motor does not perform like it needs to

Panoramic sunroof rattle. Sunroof completely closes, sunroof motor starts rattling then sunshade doesn't close.

The other day. The wife parked the car at work.

She said it did not want to start. I checked it out and brought my OBD reader. It threw out some codes of concern initially for the CAMSHAFT Sensors.

I had it towed to a nearby shop and they said the CAMSHAFT POSITION SENSORS had some oil on them and to have them replaced.

I towed the vehicle home because I did not want to pay the crazy labor to have sensors replaced.

I went ahead and replaced the CAM sensors, and nothing!!!

Still back to square one.

I also had my neighbor come by for a second opinion. First thing he checked was the Fuel pump. Also nothing. No humming or noise showing indications that fuel is being distributed.

That is the last time we troubleshoot'D the car. I am stuck and don't know where else to check.

I did a lot of reading and checked the MB Forums. It seems that a lot of issues with this car is pointing towards the CPS.

Please help!

alternater is fine . afer it sit's awhile after driven some noise comes from the passengerside and we disconnect the battery so it won't drain it

Replaced the alarm box at the dealer but still occurs, it has been to two different shops and no one can find a problem, any ideas?

I have to drive with a pillow behind me

The battery and alternator checked and ok... it has power but wont turnover all the way... I had the coolant low light on a few days ago and I added proper coolant. It seemed a bit rough running. My instict is ignition switch or starter cylenoid. Could it be a sensor regulating fuel? I just made my final payment on the lease less 1 week ago... I request direction in Diagnosis... any recommendations for troubleshooting? It acts like it wants to start but is not getting fuel... its dark and I have limited tools and would like to inquire before taking to shop and getting my pants pulled down over price

turns over but will not start battery good all lights on but car will not start
