Had a massive WTF issue last night...
Replaced the 044 with the new Walbro E85 416l/hr pump and all went in fairly well. Went to test the thing and no dice, didn't prime. Turned the car off and it started priming and kept running, turned the key back on and the pump stopped, key back to off and the pump started again.
Was late and I was high on E85 fumes so I gave up but still can't work out WTF I have done, none of the wiring or terminals on the relay changed. Literally just pulled old pump out and installed new one.
