What do your spark plugs look like? All tan? Maybe one is a lil different looking?
For a while my Z was runnin really shibby... pulled the plugs & #1 didn't look as clean as the others. Pulled the fuel rail & cranked the engine & #1 injector was barely spraying.

New injectors or send your turbo injectors to have them re-built and flow matched.
Either way, go to: http://www.rceng.com
Get a price quote for a rebuild or new. Make sure you specify flow tested and flow matched.

This other set of injectors look nice and clean. I swapped out the JSK rail for a stock turbo rail with injectors. I re-used the o-rings that were on that used rail for consistancy so it sets the same on the manifold. (I'm mising one o-ring from my new set)
anway, right to the point. The car won't start. I've got no fuel coming through the injectors!!! I spent all evening on this and now I don't have transportation to work.
I reset every electronic component here, and reset the battery. There is fuel pressure coming out the back of the regulator when the line is off and I'm using the same regulator that I had in there today.
This makes no sense... the spark plugs are dry

ALL SIX injectors were bad. I put the JSK rail back on and it fired right up!
Ok, so I also used the larger all enclosing type injector holders instead of the aluminum two-piece ones. That was my problem the whole time. I mean, basically ALL the problems. The car doesn't buck or pop at all even giving it sudden full throttle from idle. It has soooo much power.... I only had time for a short drive but it runs good.
good night

Night Bleach,
Congratulations on finding your fuel issue! It was only a matter of time till you figured it out. Now to get your car tuned a bit more on a wideband O2 sensor, you really need to get it tuned, the difference between the two is astonishing!

Just as a backup though I think I would send the other set of injectors out to be rebuild or maybe pick up a slightly larger size so you can turn up the boost a bit more

Now I need to get that A/F gauge plugged in, adjust the AFM, and fix the wastegate.
