Lost a belt, which caused overheat, which resulted in coolant spray penetrating MFU (a.k.a. MFRU) connector, which cooked the fuel pump pin and socket in the connector and MFU. Tried a direct bypass from the accessory socket as a temporary measure, but the fuel pump seems to be drawing huge current now, heating up any wires connected to it in maybe 10-15 seconds.
Fuel pump is just over a year old, and I have got to believe the overheating and fuel pump "going bad" events are related, but don't understand how. More importantly, I am unsure of where to look to resolve the issue. Clearly there is increased resistance somewhere, but any ideas on where to look first? Any suggestions greatly appreciated, as my car is 400+ miles from home at the moment.
I'll be ordering a replacement MFU as soon as I figure out which one I need to get as a suitable replacement.
edit -- TechTalk search (yes, I searched first!) suggests wire from reset switch to fuse box as a likely culprit, but would this affect the accessory socket bypass? Electr *idea*cal things are not my specialty.
