Ph1 revival

The bodge is still there. it basically bypasses the relay and provides a permanent 12v to the coil pack. To be honest, it may remain long term depending on what amperage the coil pack pulls.

The potential fallout would be adding a drain to the battery but the feel appears to cut out when key off.

I cut the battery isolator when I leave the car so in this case it would be fine either way.

Couple of things , if you’ve shunted to the perm power then it will drain as coil pack will remain powered , but if you shunt to the ignition side power then it’ll turn off . But as you say , those two different circuit's are protected by different fuse ratings so be cautious.

Getting back to your issue , I suspect that the relay control wire which is an Earth control via the ecu ,that wire needs to be checked for continuity and resistance.
Fuel pump controlled earth by Pin 68 of ECU. ORANGE wire.

I've shunted to the perm live. bridging to the switch could draw too much current for the wiring and blow a fuse. I turn the battery isolator off when the ignition is not on so it wont drain the battery. But yes, i should probably find a more appropriate solution.

Interesting to know that the relay is controlled via the earth. I will have to find which pin on the ECU that will be.

Note that this is a ph1 that has slightly different pinning on the ECU - also I am using a GEN90 aftermarket ECU. The fuel pump is controlled by pin9 rather than pin68 but i was getting 12v at this pin. But it is the coil pack relay that is the issue, is this on the same circuit?
