3v1Ls14 is an unknown quantity at this point
So, i put more gas in one day and then it decided not to start, unless it had jump start (ether mix) sprayed into the filter. fuel pump magically stopped working. Relay shat itselt, so I wired in a new one. Pulled injectors and they were injecting, not very much though

Noticed when i turned IGN to ON, pump just kept going, it didnt just prime.
I rigged up an inline fuel pressure gauge with some fittings and a gauge I had laying around, to check what the pressure was.




Turns out, with the pump that was already in the car, the gauge gave me just 22psi.



I swapped that out with a brand new pump and it jumped to 40psi. But when i cranked it over, the fuel pressure showed that it was dropping when cranking (as no power to pump during cranking, only on ign ON). so i tried constant voltage to the pump from a battery sitting in the boot and with power while cranking the pressure stayed even during cranking and it started straight away.

Im not entirely sure what has happed. fuel pump was crap. relay shat itself. now pump wont prime, stays on. and wont start unless constant voltage to the pump during cranking

at least i got it working again i suppose haha... for now
