ECU Pinout

[Red_101au]

I have gas fitted to my Pajero and it works fine but she will not run at all on petrol...
after testing I find that the injectors are not pulsing on one side...
suggesting they are being earthed out
I have come to the conclusion that possibly the ECU is not allowing the pulse to switch on again when selecting petrol...

so I am wondering if anyone may have a Pinout Diagram for the 1990 NG Pajero...
so that I may be able to check and test the injector from the ECU

regards
Bob

just had another thought....
could a faulty crank angle sensor stop the injectors from pulsing on one side??
and if so.... how does one diagnose a fault in it?
