Thanks Hog, as per the speed sensor wiring to and from ecm etc, there is no link to ignition.
I am flying out tomorrow to go back to work for 2 x weeks, I'll have another crack at it when I get back.
I'll repost then........................
McGregor . Reminds me of a similar problem. Norton commando, last year gave it a service , plugs etc. took it for a run, just starting up the mountain where i live it would die/stop as if switched off on the first gradient. Turn it around roll down the hill it would fire up again, charge back up the hill same spot it would die again. Like hitting the wall on a hill climb, Checked fuel, petcock, cap etc for vapor locks, loose wiring everything, spent days searching for answer, on flat road fine, going up this hill same spot dead as a dodo. Even investigated old urban legend about "that spot" where cars roll up hill etc due to magnetics lol, Turns out it was wrong heat range plug, overheat =switch off, roll down hill cool down=start, At least ten experts swore it was a fuel problem i was chasing
Not highjacking thread, but maybe plugs worth considering
Cheers
Sorry, Hogbagger, is this chart suitable for my model? Mine is a carby 2000 with only an ignition module and sensors,reading thru the list it appears to equate for a later injected model?
