Hi,
I am having problems with a non starting ABY S2 and after ruling out most of the common mechanical failures I am starting to look into the immobiliser.
Would the factory immobiliser prevent the fuel injectors from activating and prevent start up, or would it start for a few seconds and then stop?
The iimmobiliser warning light on the dashboard comes on for a few seconds when the ignition is turned on and then goes out, and does not flash when I try to start the car.
The origonal problem was non starting, but after being connected to a heavy duty battery charger with a boost function it started popping fuse 27 and had no spark or fuel pump activation on cranking.
I have tried a non immobiliser ECU which stopped the fuse popping and restored the spark and fuel pump activation but the fuel injectors are not opening.
I then got the D900 and D901 diodes replaced in the origonal ECU, which has also stopped fuse 27 popping restored spark and fuel pump activation, but I still have no fuel injector activation. I have 12v at the injectors and checked the restance and they all are in spec.
I have also replaced the cam and crank sensors and checked the timing pin on the flywheel, so have ruled out most of the common mechanical failures.
The earth and power feeds to the ECU all seem to be ok too.
I see there is a module under the dashboard, is there any way to test/bypass this or would I need to buy a 2nd hand module and key to test if this was faulty?
