Struggling with this non-starter and I don't have any info on this model. No sparks, no injector switching, no fuel pump running on cranking.
Can anyone supply a wiring diagram for the ECU pin numbers (Siemens). I have power to coil pack, crank & cam sensors, throttle pot, airflow & injectors. Scope pics look good on cam & crank. Crank sensor is 3 wire, 12v feed, earth & signal. Signal gives 5volt square wave, 13 @100m/s, does anyone have resistance figures for the crank sensor.
Does this model have an inertia switch--can't find one. Is the immobiliser in the ECU or separate? If separate can I disconnect it?
A new ECU is available and has been tried with the same results. Thanks for your help.
