Not the pump...

Would that it were that simple! I've checked the pump and it's ok.
There's a wire going from the alarm system brain to pin 60 on the Trionic ECU. According to the book, the alarm system supplies +12V to this pin to activate the fuel/ignition system. That signal is behaving very strangely - with the key on and the connector unplugged, I read 12 volts on pin 60. But with the connector plugged in, it stays at zero. I wonder if the alarm and trionic ECU's are sending data back and forth on that wire somehow?
