Yea the butchered one is an ecu plug, it has about 24 or sumthing pins but ill check wen I get home, and ill check the rest of the plug pinouts then aswell

Ok so im getting sumwhere now

Found out last night that the efi relay had no power going to it on the switched side so fixed that and I now have spark and fuel pressure but no injector pulse

do you have power to the injectors?
Is the ECU properly earthed with those wires that are bolted to the intake manifold?

Yep injectors have a full 12v n is it the ground wire that connects to the body near the strut ur talking bout?

If so then no I need to connect it, I didn't know rthat was ground for the ecu

in factory wiring loom, there are a bunch of wires connected to an eye terminal that is bolted to the intake manifold. This is the earth wires for the ECU.

Check the ECU earth pins to make sure they are earthed properly (disconnect plugs from the ECU and test the wires)

Yea all the earths are good on the ecu....

Also just realised I have no ignition light on my dash wen the ignitions on and my stereo no longer gets power ???? Im confused now

You've got two options here:

1) use the electrical wiring diagram and diagnose from the dash light backwards to fix the symptom; or,

2) start at the beginning and check that you've got your power circuits running, so 12v to all the relays & fuses with the ignition off, then at accessories, then at on, then at start. Then move to the next part and work your way through.
