1992 Mercedes Benz E300 stalling, at idle, rough idle

When it won't restart, check fuel pump pressure and check to see if there is spark to the plugs. One will be an issue. Let me know what you find.

I've got constant spark during turn over, run , and when it does not want to start also, I put fuel pressure gauge on top port of the injection system ,40# with key ON, 80# when turning engine over, and it won't start.

Do one more thing for me. When it refuses to start, try starting fluid and tell me if it starts at least for a few seconds.

I've tried fluid also, won't start, I'm looking at the crank sensor, gettin 900 ohms, but only 0.225 ac voltage,,I already ordered new one, just in case, also testing with different meters, same voltage maybe the overload relay behind battery?.

If it doesn't start with starting fluid, then it either isn't getting spark, there is low engine compression, or the ignition timing is wrong.
