Is your pump running?
Is it leaking gas anywhere?
Are you pulling a vacuum on the gas line through a pinhole?

Not getting pulses from the computer. I'd check your wiring.

Ditto
If you have fuel in the lines they are either ALL clogged, highly unlikely. Or they just arent working.

I have a stock fuel regulator on my 331 with 24# injectors.. But I have it chipped, so it gives good fuel pressure.. my stock PCM had me running very lean at idle and somewhat lean at full throttle.. I had an adjustable one but it started leaking gas through it...

definatley no injector pulse....check your pcm, hot wires, and check to make sure you have sufficient ground. either your pcm is bad, or it doesn't know that it is on...just my opinion....and a hot injector wire doesn't mean anything if u don't get a pulse. i had a poor ground that started that problem for me, which ended up frying my a9l. is your car a efi convertion? if it is ground pin#'s 20-40-&60 straight to the ecu to the body. just a suggeston, not sure if that's your problem.
