This actually started years ago but cars been off the road. Originally happened when mate was helping test a fuel issue. Turns out the car was stuck running low voltage to the pump so he jumped straight from the battery. Then car wouldn't shut off via key. Rewired the connector by the head light and relay from the pump from a write up I found on here. Put in a fuel cut switch with fuel cut and battery isolation switch is how I kill the power backfeed. If you start car then off warning cluster stays on with key off. If just turn key to on then off warning cluster stays on. Pull ignition switch plugs it all stays on.If I pull btn fuse car does not shut off. Pull either of the main relay plugs car shuts off. Pulling alternator plug does nothing. Pull egi comp kills car and cluster. Any more info?

Is deleting all that fuel related nonsense and going back to stock an option at all?
Low voltage to the fuel pump was an issue that coulda been solved without involving any of the rest of the harness. all that stuff just made things worse.

The fuel pump resistor relay was stuck in low voltage mode. No longer have it. Probably thrown when we moved house. It was testing if car was running lean under load by adding straight 12v to the pump that shorted something. But yes probably be much easier to locate the problem if I hadn't done what few people do which is do away with the resistor relay.

If there's a way to wire in a made up replacement I'm game.

yes, eliminate the backfeed by simply cutting the wire leading from the front harness towards the pump before where you added the battery power wire.

simple, yes?

Ok so on a hunch I just checked something else. the b/w of the main relay 4plug had been joined to a b/w wire running towards the left headlight through the front of the car. It was disconnected when I bought the car so something I had done at some point. Face palm. (No idea what the rogue wire is supposed to run to)With it disconnected car functions as normal, starts, runs shuts off via the key. Coincidentally the b/w wire from 4 plug at the main relay is supposed to run to the fuel pump resistor relay and from there to the air bypass solenoid valve and I think other emissions stuff which has all been removed. So should be fine to run this way or do I need to have it join the correct wire? There are several things removed and hacked before I got the car as a rolling body.
