1989 Wagon stalling
 

I just pruchased a 1989 wagon and it stalls after running for about a half hour. It won't restart until the next day. Any ideas as to where I should start looking?

Start with the basics...is there spark when the engine won't start?

Does the engine get fuel when it doesn't start?

Stalling-
 

It sounds like the OVP relay to me- do a search on OVP. You will see what I mean... I had the same problem with my 1989 300CE with the M103 engine and it drove me NUTS for weeks- after throwing parts at it, I found that this was a COMMON culprit!

The OVP relay is located behind the black panel right in back of the battery in the engine compartment.

Lots of luck!

I just purchased this car and it hasn't done the stalling to me yet as I haven't put her on the road yet. The previous owner told me of the problem, that's why he was selling it. I will check for all that has been recommended. Thank you all.
