Fuel Pump problems.... Help with a new relay please

[MrSoutherland]

So I'm trying to finish my sr swap and I'm having problems with my walbro. I have a jumper wire from the power wire to the positive terminal on my battery in the trunk. I have to plug it in and unplug it when Im starting the engine. If I leave it then it just floods my engine....

What's the best solution for this? I read about getting a 30 amp relay and put a switch in between for a kill switch. But will that fix my problem or just cause more s***?

Btw- there is some faded writing on the ECU- It says "fuel pump" and nothing else. Does this ECU have a problem with the fuel pump? My importer said he had it tested in front of him on a car to make sure it was a good ECU. But did that car already have a kill switch in...
