First, that fuel pressure thing needs to be resolved. Sounds like a new regulator is in order.
Second, you might either clean and install or buy some standard (AC Delco) plugs and begin again with a fresh, clean set. Then we can go from there.

FWIW, with the fuel pressure all over the map, the fuel flow is too, and the ECM and O2s are not able to provide accurate fueling information - mostly rich, is my guess, which will foul the plugs to the point it may well be a subset of your starting problem.

Just my 2 cents.

Paul:

Your 2 cents is worth it my friend.

Just to clarify.

Plugs:
The plugs are brand new after the sooty ones were removed, maybe 10 miles on them.

FP Readings:
Normal at part throttle very steady, varies with load 38-55psi. Then vibrates excessively under WOT 48-60+ psi. Hard to tell how high/low it goes as u can barely see the needle its moving so fast.

No Start:
If you let the car sit all night and go to crank it it starts just fine no prob. If you turn it right off and try it again it's a 50/50 shot it will start back up. Again if you let it sit for hours it will start right back up no prob. FP readings are normal. 45-50psi and slowly leaks down to 30's after 10 mins or so.
