Hi everyone, I have asked this before but I still cant get my car going. I have a stock vx ls1 in a VB commodore. I have a remapped maff less tuned computer with VATS removed. All I want to do is use the computer to run the engine. I will wire everything else stand alone. (IE fuel pump, brake lights, engine fan)When I power up the computer Pins 19, 20 57 on the compter I can hear the throttle body start up like as if it is ready to start. When the ignition is on I have power going to the crank angle sensor, But i cant seem to get a signal back, (I have put a new Crank angle sensor in)Also I dont have any power going to the coil packs. Do you think I need to have the body control module and power interface modules hooked up. ( I have tried connected and not connected).I have earthed out the computer via the red and black wire. I dont have a diagnostic connecter hooked up because I only have the engine wiring loom, If I was to connect it up has anyone got any ideas what wires to hook up to it??? Thanks for everyones time in this matter

im guessing you were using my post from this thread for the wiring diagram?

the power for your coil packs would of come from just an ignition relay in the original vx, so you have to find these wires in the loom and wire up an ingnition relay.
your injectors will need to be wired the same as they all share a common ignition feed.

Ok thanks for that I have had a look over some other wiring diagrams and I think I may need to put some power onto a red and light green wires for the coil packs, I will have a go tomorrow and let you guys know how I went. Cheers
