Then it became more frequent ive had to by pass the key n start it by the starting solenoid a wire with push button inside my car but that to has given up on working.

Overheating issues

10 Mar 2020 •
1998 sl500 keeps overheating. Changed radiator, water pump, thermostat, hoses, clutch fan, resevour, checked head, no oil in water, no water in oil, no smoke or water at tail pipe, runs fine until temperature reaches 90 degrees +\- then starts to heat up. Water in reservoir boils. Hoses are hard with water but see or feel any circulation of water. Pump is new. What else could I check? Could it be a bad sensor or vacuum signal of some type for coolant to go to heads for cooling? I'm stumped. Please help

Is anyone aware of an accelerator problem?  This has now happened to me twice.  I applied the brake to come to a stop.  The van slowed but the engine (diesel) did not and when I applied further pressure, the rear wheels started to spin, squeal and throw dirt.  When I realized I didn't have control of the vehicle, I hit the Start/Stop button and the engine quit.  I'd appreciate any comments.  Cal.

MB W203 Oil in vacuum pump

9 Mar 2020 •
I noticed an oil leak apparently coming form my vacuum pump.  I replaced the vacuum pump, but, when I opened the old pump, there was oil inside the pump.   Is this normal?   Was the car overfilled with oil?  It looks like it's still leaking.  Should I replace the oil separator (and cover) (on rear left) and on right valve cover? suggestions?

I had a bad fuel pump on my 96 e320. I replaced pump and filter and dumped bad fuel, I have great pressure now. New battery, cranks fast. It will only run with starting fluid. The car sat for 8 years and only has 50k on it. Its on jack stands if that has anything to do with it. Im a GM guy, never had a benz Thanks to all. HELPPPP!
