Hi there, I've owned a black 550 in Australia for about 6 years and I love it very much. Unfortunately it's parked up most of the time as I spend most my time outside the country. Last year when I put the car away the alarm was doing some unusual things like turning on the front parking lights and the siren was going off unexpectedly which led me to unplug it. I've now plugged it back in and the alarm is working as it should - I get the right amount of beeps to disarm and the red led goes off after about 6 seconds - but the car won't start. It has spark in both banks but the injectors are only getting voltage on the left bank and both fuel pump fuses aren't getting power at all. The fuel pump relays seem to be getting power in on a couple of pins but I'm not sure what that means. Does anyone have any suggestions on what to diagnose next? Could it be the immobiliser even though it's communicating everything is fine? Thanks,
