I apologize in advance, as this will be a lengthy post.

98 Eclipse GS, 420a, T3/T4, FMIC, SFMU, Walbro 255, -6AN everything, FCD, 8 PSI WG, manual BC at lowest setting, Crower stage 3 cams, fully built bottom end, 450cc RCs

This thing wont idle at all. I realize with a huge cam idle will be terrible, but it wont run at less than 25% throttle. I tried setting fuel pressure to 40ish for initial start and it fired up, but ran horribly. The lower I go, the better it runs, but now Im in the 10-12 psi neighborhood with KOEO. I installed the lowest cal disk on the SFMU. Also, my KOEO fuel pressure leaks down immediately. No idea why. Im running -6AN supply line to a firewall mounted Edelbrock filter, then into the OEM rubber line that attaches to the OEM rail, fuel pressure test port Schrader valve removed which goes to a 100 psi gauge, then to the SFMU, and -6AN all the way back to the tank. OEM FPR and filter removed. As throttle is applied, the fuel pressure is actually decreasing to 0 psig.

FCD is wired up to the MAP sensor, but the green switched 12v wire isnt connected yet (I figured I would get the idling and driveablilty out of the way before worrying about cut). Could that be an issue? I applied 12v to it but no change. Though I havent checked the voltage reading of the FCD like the manual says to.

Turbo doesnt seem to be making any boost. Nothing on the gauge or anything audible. I can visually watch the comp wheel spin though. And Im getting grey smoke out the the wastegate exhaust port. Normal?
The WG, boost gauge, BC, and SFMU are all T'd into the three prong vacuum port on the intake. Is that an issue?

Wideband says it running wicked rich, 9.8:1 area. I think Ive got too much injector size, but Id appreciate it if someone could help out. This isnt my car, so time is something I dont have, unfortunately.

To sum it up:

Why is the fuel pressure leaking down?
What is the best fuel psi (approx.) with my setup?
Am I running too big of an injector size?
Why no boost?
Should I install an vacuum canister due to the cam size?

Any and all info will be greatly appreciated. Thanks, 2GNT!
