Solved
I scoped the cam sensor, all good there.
Went back to the fuel system, started to ohm the injectors, started with #5, ohm'd ok, but did not open on batt !!
Yeah, 6 of the 8 were stuck closed !!! Had to bump them a few times with 30v. Wow, went around is a circle, but, some things are now new, so more peace of mind, etc. Luckily I still had some toyota style injector connectors laying around, so just made a 'whip', plugged into each one, bumped them all, now it runs

It happens sometimes after RC does their service.
The box they send them back in literally says on a sticker inside the box "Install injectors immediately". Well, mine sat for a week or so before I actually installed them. But, 1.5wks is not typically long enough for them to dry out in their wrappers.
I spoke to RC tech support today, this happens from the cycles they use to process the injectors, using various fluids along the way, the last step is a blow-out (all filtered of course). They can get "sticky" if the sit too long.
It was just my luck. "Next time" I will bench them before installation
It runs gooood now

but by any chance what did you use to resurect stuck closed injectors?
I might have a similar situation on my is-f
Our Battery is actualy near cyl #8 pass back side. But same situation. Was unbolting wiring harness ground to head cover and touched + terminal on battery.
sparks, blew 2 fuses. Car wouldn’t even crank (after fuse replacement and t cranks but no start) fuel pressure is all good though. Pump works, fuel in lines confirmed.
I did install 8 GB reman direct injectors (they also claim to flow test them, clean them n all)
but as mine are rare, and I didn’t install mine till 1 week after I got them, IS-F’s are more rare then GX’s I wonder how long they set on the shelves in WH, as in could it possibly be that they’re stuck closed too?
what did you use to bump them open? And how did you check?
thanks
