RE: Wren 54 mk3-PLEASE HELP!
Mark,
We think it sounds like a wiring problem, but if you are sure you've got everything plugged in right and that the glowplug wires are twisted together, then there may be a problem with the ECU. Please PM me with a phone number and a time when you can be reached, and I'll get one of the guys to talk to you. If the ECU is faulty we can replace it.
