According to DRE99gsx on supraforums.com who has similar problems: "btw, I found the problem, and SHE STARTED! After inspecting all 3 sensors, I determined that the crank sensor
was the only unknown. I compared the intake cam with a stock intake cam to verify the cam sensor tabs were in the same locations, 180deg apart. They were. Since the sesnors and wiring all checked out, I then proceded to verify that the crank timing plate was in the right location. Well, it wasnt. After removing the timing belt
covers, I noticed the timing belt was not using the entire crank timing belt
gear. 1/8th of the belt was sticking out past the rear end of this gear.
Turns out the timing plate behind the gear was not pressed into the gear. I thought you slide on the plate, then the gear, and they press into each other (as long as the plate's tab lines with the gear's groove). I guess not. I removed them both and pressed them together in a vise, heard a click, and realized this could have been the issue.
The crank sensor was seeing erratic signals as I was turning the crank. I'm sure if I had an oscilloscope handy I could have caught this quicker, but through process of elimination, gold was scored.
Thanks for the help. She fired up and idled like it should. 80psi oil pressure (cold), fuel pressure was good, etc etc. "
