Ready to race!
Primed the motor for 30 seconds tonight after reinstalling the motor and broke a fuel line connection and started missing after.
Touch of background, had the motor out and trans out to do the clutch, diff, rear main seal, cam chain tensioner, cam cradle seal, carbon cleaning and to replace the broken exhaust manifold gasket caused by the sheared stud in the head, the reason for pulling the motor.
Primed it to feed oil to the turbo, held the key for exactly 23 seconds before it stopped cranking, figured the small motorcycle battery I used ran out of juice after sitting for a month, or the ECU cut it out. Five to ten seconds later I hear the all too familiar sound of a hose popping underneath the car and fluid hitting concrete. Quickly realized it was the lower of the two lines on the rear side of the fuel filter. The part of the quick connect that depress to release from the filter was gone on the lower connection and the line was hanging, of course it broke because of the built up pressure while priming.

Had a friend with me, figured I'd still fire the car and let it run for the first time with everything back together for the first time in a month while he offered to hold the fuel line on. Did so, fired first crank, ran smooth, and started missing 10-15 seconds in, pretty sure when the SAI cycle finished it began missing. Killed the motor and ran the codes. Random multiple cylinder misfires. First code being cylinder one, second being cylinder three. When I did the carbon cleaning, all four injectors came out with the intake. Replaced all four blue o-rings that meet the fuel rail, but only the teflon seal on cylinder one after realizing what a bitch that job was with out the expensive kit to reshrink the teflon.
Pulled the coil pack and plug from 1 and replaced both with cylinder four's respectively (cylinder 1s plug looked a tad bit wet on the threads, assuming it was fuel), cleared the codes and fired it up again for about thirty seconds. This time I applied a bit of throttle to around 2k rpms, and while applying throttle there were no misfires. If I hold at 2k rpms or let idle it misses. Shut it back down, ran codes, same codes as the first time. Everything sounds good and feels smooth at idle and while applying throttle until it misses.
Just wanna throw everything out there that I've done since the last time the motor has been turned over before assuming it's anything.
Anyone ever have one of the quick connects break on them? If so can I replace just the connection or do I have to replace the entire line running to the fuel tank. Should that line have even broke priming the system?
I'll start with that fuel line/quick connection replacement, then do plugs if it doesn't resolve the issue, not sure how one or more than one could have fouled during anything I've done, but I've had plugs go on me before, also had an injector go before, and the intake manifold, all feel the same, with rough idle and random misfire condition. If either of those don't do it, I'll pull the intake manifold and at least injector one to check the o-ring as well as the Teflon seal I changed on that injector (what I honestly think is most likely the problem) Worst case scenario if none of that resolves it, I'd assume the flap actuator on the manifold somehow went, and the manifold is toast, an injector somehow went, or there is something clogging the fuel system which I find unlikely.
Thanks for reading if you got this far, I know it's a long one. Any input or suggestions would be appreciated, I feel like I am probably on the right path but any help is appreciated, thanks! So damn close to enjoying a clutch and throwout bearing that doesn't squeak and a diff!
