Fuel pump drawings none starter problem

[mspdan]

right...

bit of an update, i have wired a live off another battery and a neutral to the pump and it turns on and the car will run so that rules out ignition, ecu and immboliser if i am correct?

the earth is connected up fine on the bulkhead behind the throttle pedal, guessing i need to check the reistance on the earth next?

also where does the wiring come into the interior from the engine bay to see if i can see where i am loosing voltage please as im a bit stuck on which section to rule out next...

maybe try another earth to the seatbelt anchor from the pump and see if i then get a live on the pump wiring and it turns on and runs

thanks for any help in advance...
