Injectors - aftermarket vs remanufactured vs service

[Franco Cozzo]

Extended crank can be fuel pressure check valve no longer works properly, you go to ignition, fuel pump pumps fuel to the rail and then it seeps back out of the rail when the pump turns off rather than holding it in the rail - then you get the extended cranking before it fires.

Common problem on Commodore of the same era, not sure if it's part of the pump assembly on Falcons

Swapped the pump with a spare that I had and still the same, so I'm assuming it's not part of the pump, or if it is then that's not the cause.
I'll do some more digging around on that.
