Hello,

I have a 1990 240DL wagon. About a year ago she died suddenly - diagnosis: no gas getting to engine. Turned out that the part of the ECU controlling fuel pumps was dead. I got it "fixed" by some place that charged $700 (!!!) with a one year warranty and the car ran fine for thousands of kilometres.

Last weekend the same thing happened again, this time 300k from home. It turned out the be the same problem again, and the ECU is currently being fixed under warranty. But I'm left with the problem of trying to prevent this from happening again. Any suggestions would be very much appreciated.

Thanks,

Chuck

/// Be sure about what wires are burned inside the ecu. The fuel pumps are controlled by relays. There would not normally be a heavy current on that circuit. (Any thing is possible.)

There are other control lines that will fry the ecu. Look at any lines that do control motors.

Motors have brushes and armatures, they can stick, stop and the motor will not have the reverse induced current caused by a running electric motor to limit the motor's current draw.

I can't help much on this mod but I wanted to caution you about the fuel pump and the relays that carry the heavy pump current, not the ECU.
