I was going for a little drive yesterday afternoon, enjoying the lovely smooth new bearings I fitted the previous weekend, when all of a sudden the engine stopped and could not be restarted.
I failed to make it go, and neither could two AA men. The engine died as if it had been switched off, and that was the end of that. Trip home on a flatbed truck.
It's a TD5 90 Defender, 2006 model year.
Any ideas?
Below are some of the things I've checked already:
Oil in loom? No, loom was new two months ago and the multiplugs are dry.
Crank position sensor? Probably not, I've tried my spare and still no go. The Nanocom is obtaining some cylinder balance values when I crank it on the starter which suggests it's sending a signal.
Fuel pump and fuel system? AA men checked for fuel supply at the fuel pressure regulator, and pump current draw (within normal range), besides you can hear it whirring. They felt it would be drawing more current if it were fighting a blockage
Wires, fuses and relays? I've started working my way through these. All fuses under the driver's seat are OK, and relays appear to be working. I did find a couple of loose wires, so I went through them all and soldered them to their terminals in the relay housings. Didn't solve the problem but a useful job to do anyway.
Earths? I haven't physically removed and cleaned them, but the multimeter says near zero resistance between engine block and negative battery terminal. There's also near zero resistance between the black (earth) wires coming out of the ECU and the battery negative terminal.
ECU? I think it's OK. I believe you usually get a 'topside switch failure' message when it is duff, but I could be misinformed.
Nanocom error messages? Just the usual 'tachometer open load' and 'gearbox abs drive open load' (well, it doesn't have a tachometer, auto gearbox or ABS, so it would say that wouldn't it?). Nothing that gives me any clues.
Mechanical fault in engine? Probably not. The AA men had it going by spraying stuff in the inlet tract, and it sounded pretty sweet.
What am I missing?
