1991 300E Stalling
I started having a problem with my 1991 300E (223,000 miles). It died on the road. Starts OK and runs for about 30 seconds and then dies. Will retart immediatly and run for about 30 seconds before dying again.
I was able to limp home 5 miles by constantly restrting it after stalling.
Any help on where to start looking would be appreciated.

Stalling
So the fuel pump was the problem?
My filter is about 1 1/2 years old.
When the ignition is first turned to the "On" position the fuel pumds should be running for a couple of seconds. Is this correct?

yeah turn it to on you should here it for like 5 seconds and so they are pretty loud not that loud but kind of luod on a house garage. cheaper ones are in a junk yard i got mine for like 12 bucks in cali. and the fuel filter brand new is like 28 bucks at auto zone while you at it change your plugs because it looks like you are running lean and might have busted them. yeap i went through some like 3 sets of plugs just to find the right one and the clearance is .032 - .036

Your fuel pumps should run for a bit with the key in the on position.
This will prove the fuel pumps.
However, once the car starts a tach or speed signal (yellow/green wire) is required to keep the pumps running.
The two critical points are the OVP and Fuel Pump relay behind the battery.
Check the fuses on the OVP.
Both relays are inexpensive to replace.
Still a good idea to change fuel filter if your not sure of how long it's been in service

Problem Fixed
Picked up a entire fuel pump assembly from a 1989 300E for $100. Replacing it was easier than I expected and it now is running fine.
Thanks for all of the help.
