Default Cranks, won't start

Got a problem with my 97 Trans AM. I have been having an issue with my engine cranking but not starting. A while back I had to replace the dreaded optispark because I was having misfire issue. After pulling the opti off and opening it up I discovered that that metal pointer on the rotor was loose, and thereby not making good contact. After getting the engine back together I began having issues with the engine not wanting to start or stay running.
I was finally able to get the engine to run if I put a little gas in through the intake. but would not stay running unless I gave it a lot of gas.

Now it won't even start at all, it will crank all day but that's about it.

I have checked the following

I have good spark at the plugs.
Checked IAC, TPS, MAF, all are good
Fuel pressure is good up to the rail
Injectors do have power to them (pink wire), resistance on all injectors is approx 9.1 ohms. Not sure if they are getting the signal from the ECM
-> I will check with a noid light this evening, but if they are not gettign the signal, what would cause this?

-> Is it possible that the CPS is faulty? Is there anyway to check it? Would this cause the ECM to not send the signal?

Please help this thing has been driving me crazy for the last 6 months.

Might be the fuel pump, mine went out, was doing the same crap. Easy replacement, took 15 min. Just need a dremel... lol If you hear it wine when you turn the key on, then it is not that.
