After previous post regarding non starting everything has been checked fuel pump is working but no power to it does not prime up no voltage to it at all? Checked spark and wire from coil to ecu is ok can hear fuel and ecu relays click on changed fuel one anyway. Also tried spare ecu

Anything else? just going outside to check the inertia sitch

Bypassed inertia still no joy , However if i hotwire fuel pump it runs fine? How many lives should there be to fuel pump relay i have one?

Have you gt a multi meter?

Test the out from the relay to see if it is actually supplying power

If it is try another wire connecting the relay to pump.

It it works then there is a break in your original wire.
