Under the steering column were u plug in the tech 2 scanner

OK the OBD2 connector.

That puts the PCM into diagnostic mode.

I have noticed when I try crank the car the interior light and green light around the key goes out Is this normal

this is getting scary
you need to check some wiring diagrams, but sounds like you have missing negative to your ecu
dont keep playing you are likely to burn something out

Update so now i ran a wire from starter relay pin 86 to the battery for earth and the car starts without the bridge in under the dash also starts when bridging the relay with wire in pins 30 and 87 is the ecu stuffed?

Good news update.
So turns out you can't use s1 l67 wiring harness with s2 cause the 3 plugs near the brake booster 1 of them have 2 missing wires also the bcm ecu pins are in a different spot so changed the harness why engine was still in the car but of a prick connected all up fired up straight away just thought I'd update incase others run into the same problem cheers guys.
