ok ...so today i removed the cold start injector pipe (fom the MFI end as i have a spare) hot wired the fuel pump and fuel came out the end into my bottle...also when cracking off the 14mm connection to the MFI unti there was lots of fuel pressure,
i am assuming that means it would have pressure to the 5th injector however...when i bought the car the seller said there was a thermo timer switch bypass wire under dash ( which i have chased up to the brown wire at the 5th injector, could be grounded under dash when connected..(CAR STARTED AND RAN PREVIOUSLY REGARDLESS OF THIS WIRE)..as stated above all issues started when i swapped fuel filter?
did'nt swap back to old filter today as wanted to report on the fuel going yo 5th injector but still not firing?
i still think it has air in the mfi unit? maybe locked the diaphragm?
i am in australia and like 5 of these cars here...crocodile dundee mechanics will scratch thier heads for hours ......any other ideas lad?
