R32 Gtst Fuel Pump Issues

[the vlad kebab]

Iv just gotten an r32 gtst sedan (first import) and im already having issues with it. A few weeks ago it broke down and refused to start again long story short my moter had no compression and was able to be pushed in gear so I out a new moter in its place. Upon starting the new moter we noticed that when the battery is conmected it instantly starts pumping fuel so we disconnected the battery and attatched the earth lead to the block of the moter and tried again. This time it didnt pumo at all (fuel line taken off to double check)

The pump is still in good working order as I used a set of jumper leads on the pump directly and it startex pumping. All the fuses have been checked and the relays next to the ecu have been changed im completely out of ideas as to what could be wrong. Theres no frayed or damaged wires etc any help would be greatly appreciated thankyou

Also tommorow Im planning on wiring it up to a switch straight to the battefy so it pumps as soon as it has power is there anything wrong with using that method ie running to rich on idle too lean on boost etc

No clue how thats relevent to my question in the slightest....

Could the fuel pressure regulator have anything to do with it?

check this link out man, different car but might be helpful. The diagnosis on there was that the pump is wired up to a permanent live (whatever that means)

what i ended up doing was wiring the fuel pump directly to the battery (havnt gotten around to wiring up relays and fuses just yet to test if it will run once the fuel pumps sorted. unfortunatly now its not sparking so i changed the crank angle sensor, ignitor, coils and plugs and still no sparking. might have to call an auto electrician for this one
