Ok Ive got a 190E 2.6 1989. I had a problem with the ignition just after I purchased it and was running an external starter button. Well, a few weeks ago the car randomly died after running for about 20 minutes. The car had not been run for a couple days prior to this. Since then, Ive changed the ignition. But, the problem remains. If cold, the car will start and run for 15-20 mins. Once it is warm, it dies, and cannot be started back up until it has cooled again. I think it may be a sensor? Anyone have this problem or know what I should do??
It will not start after it dies, it cranks over and all that fine. I just got a new battery also. After it cools down it will start fine and dies eventually again.[xx(]
The fact it dies when hot as well as not starting when hot is curious. It suggests some sort of fuel starvation, maybe the ECU is getting duff information.
Does the engine idle gradually fall until the engine is "bucking"?
Have a similar problem....I have had some bad gas, and fuel treatment helps, but it typically happens when the car has run about 10 minutes, but before it has reached full operating temp. The last time it happened turning left across traffic...[V]
Mine will restart in 5 - 10 minutes after lot's of heavy cranking and sputtering...feels like fuel starvation, but it may be even fuel saturation. Lots of unburnt fuel coming out exhaust when trying to restart.
Interesting that gas treatment helps...I am supecting a faulty check valve may not be allowing the fuel to return to tank. I have noticed a vacuum in the tank when adding fuel treatment at times like these...yes definitely a vacuum, not pressure. I have also played with the gas cap trying to be certain the valve is free. Am having the fuel system checked again tomorrow, after changing fuel distributor, fuel filter, and cleaning out the tank with a syphon in the last 6 months of fighting this problem.
