HOW LONG WAS ADAM IN EDEN (few hours) Following on since it started brilliantly without coolant. Yesterday: Connected up the electrical fans on the oil cooler and the thermo switch on the radiator. Tanked up with coolant - 11-12 liters. I have a significant voltage drop somewhere in the ignition circuit so must use a jumper cable from battery to close to the ECU loom in order to start. Started immediately with flying honors. Running SMOOTH AS SILK , as we say, on all 8. Adjusted idle to 450/500. Checking gauges working. Stop / start a few times, checking a bit. All 5 oil cooler fans working as they should. Starting and let it run, want it up to 80+ degrees in order to check that thermo switch and radiator fan relays are working. After 15 + minutes or so, white smoke spotted from the exhaust pipe serving cylinders 2 and 4. (The exhaust is normally totally invisible.) What now? Checking by hand the pressure of the exhaust coming out of the pipes, sure - cylinder 2 or 4 not working. Checking spark plug 2 and 4, they fire OK. Off with air intake conduit - checking injectors and ther plugs - sure enough - black wire broken in one of the injector plugs. OK, searching scrapyards for plugs today. Conclude to run on 7 until warm so that I at least can tick off the thermo switch and the relays as being OK. Start? Nee way. Stone dead. Not one cylinder firing. Checking wiring around coils and igniters - seem OK. Still stone dead. Have a spare ECU that I can put in and test next time I decide to have a go. Getting a bit bored with problems now. Seems Murphy is following med closesly most of the time and sometimes (too often) he catches up.
