On my Nova there is a problem, fuel pump won't run.

Ignition switched live is wired up, even when you run a direct feed from battery to Ignition switched it doesn't run.

it runs with a direct feed from battery.

checked fuel pump relay, it has the 2 12v feeds it should, but isnt getting any voltage from the ecu.

any ideas?

Broken cable?

Checked earths (3 on rail and one from box to chassis)

And cable should be fine because it was working alright when it had an xe in it

What has changed is the engine went from a xe to a LET and pump now is a walbro 255
