1991 Lumina Euro no start

[66gmckid123]

I'm at a loss as to why my car wont start, and I'm hoping maybe someone here can give me another direction to turn. I've good fuel pressure, verified at 42 with the gauge, and I have fuel at the rail. Ive got spark. The ICM has 12 volts power to it. The only code I have is 33 and 34 which are low and high vacuum for the MAP sensor. The car just up and dies on my dad yesterday, towed it home, thought maybe fuel pump was going out put a little fuel in it. The car has over 1/4 tank fired on the second try ran for a few seconds then died. I put a new crank sensor in it and still nothing. All the fuses are good and nothing is unplugged. I do have power to the injectors, verified with a test light, only when ignition is off. When key is turned to power fuel pump the light goes off. Not sure if this is my problem. If anyone has any thoughts or advice it would be much appreciated.
Thanks,
Andy
