2004 1600 diesel auto cmax
Following a small welding job to the wing on my daughters Cmax I started the car and drove it off the car ramps. The welding was done using a surge protector! The engine stopped after a couple of minutes and now I can’t restart it. There are no warning lights on the dash and nothing to indicate that I have damaged the ECU. Does anyone have any suggestions as to the likely problem?

Personally I never trust surge protectors as we have no way of knowing if it's working or not until it's to late, it seems too much of a coincidence the car was perfectly ok before and now it won't start.
I would remove the ECU and send it off to a repair specialist for checking and possible repair as you probably know you can't just get another one from a scrap yard even with the same part number as their matched and coded to other components in the car.

Thank you very much for your comments, they make perfect sense when you think about it. Although we have an unknown here with cost, time and no guarantee we need a starting point! Although the car is old it is in otherwise reasonably good condition.

Thanks for the advice.

I wonder if it could be the dash pod instrument cluster soldering? Not sure if the immobilizer is routed via there, but I wonder if giving the pod a few smart smacks while trying to start wouldnt hurt.
