Hi all
I've just gone through the pain of swapping the gearbox on my Trophy.
The thing now won't start.
It cranks for a few seconds on most tries of the key (sometimes you get nothing, but most times you get a few seconds) but never fires.
It ran fine before the work started. The work has carried on over about 6 weeks so reasonably long time without a battery.
I have put a new battery in to be sure its not that (no change)
Details I have ascertained so far:
1) The immobiliser light is solid red. I think this means functioning correctly? I have also tried both keys.
2) The fuel pump does not prime. If I bridge the terminals in the relay under the bonnet it primes but it never does it on its own. Also, never 12v at the signal of this relay so the relay "switch" is not being demanded (from the ECU?). Also, when this relay is bridged, there is no change in behaviour. It still cranks but does not fire.
My thoughts are that maybe the crank sensor somehow got damaged? Is this something that can happen? Its bolted back in place and there is no adjustment on it so I assume it just sort of works. I also don't see why this would prevent the fuel pump from priming but maybe the priming is triggered from RPM?
Or could it be the ECU? Has that gone pop?
Or is it the dreaded immobiliser?
Any thoughts from those more experienced gratefully received!
