My C220 1996 (198K mi) starts fine. I can run the engine while in park (or driving), then the engine dies. When it occurred for the first time 3 days ago, it occurred while I was driving. The engine cut out and then a few seconds later it came back on. It happened about 3 times in a row. I was luckily able to get the car back home.
Here are the items that I already checked or replaced recently:
About 12K miles ago I replaced the following:
- Replaced fuel pump (original Bosch)
- Replaced fuel filter
- Replaced fuel pump relay
Here are the items I check today.
- Replaced spark plugs (they needed to be replaced anyway and they looked fine)
- Checked power to the fuel pump relay and the fuel pump. They both get power and I can hear / feel that the pump is running even when the engines starts stalling.
- Checked air filter (looked clean- it was replaced about 10K miles ago).
When the car dies, I may be able to to start it back right away or I may need to wait for a few minutes to get it started. Then it will run and after a few minutes the engine will die again. While the engine is running, it runs clean and has power if I want to move the car.
I am looking for ideas. I saw posts about CPS, air mass sensor…..
Any help our how to trouble shoot would be appreciated.
