I had no comms with pcm , non start , no crank .
I removed and tested Main Relay and starter relay and all were good. If I ground pin 86 of the starter relay it will crank but not start.
Ecu lives under o/s/f wing and having checked power supply, I had no voltage to it - all the pins look a little green, but nothing horrific .
So I plugged the ecu back in and all of a sudden I had communication back and the glow plug light on the IC flashes on for a second or so.
Still no crank, but this time ground pin 86 and it runs.
Going back to the ECU if I ground pin A70 it cranks, so I guess I am looking at an ecu fault but I am just a little nervous that I am missing the bigger picture - why didnt I have power supply ?
Tbf I am going off a vauxhall vectra wiring diagram as I cant find the correct saab one *sigh*
Any thoughts apreciated
