Mercedes w124 260E problems?

I have a w124 260E 1990 model. The car has been parked at a garage for 2 years as I was overseas. Now when I start the car, the engine fires up without a problem but dies after 10-15 seconds and if I accelarate it dies even faster but one crank and it starts but dies after a few seconds again. Oil pressure is full and idle speeds seem to be decent slightly above 1000rpm. While the engine is running, I cannot seem to engage the gear from P to any other mode although I am pressing the brake. Lastly, the AC and power windows seem to have failed too. The stereo works fine though. What is the problem? Thanks

change the oil......its mud and the low oil pressure switch is killing power to the fuel pump....the ECM does not see oil pressure.....your owners manual spells out what to do if ur storing a car for a long time....

You need to tow the car to an MBZ dealer. It sounds like you did not do a long term storage set up and the problems have been caused by the lack of this set up. Trying to start it has made the problem worse.


good luck
