turns over won't start,got spark got fuel in the fuel rail,no pulse to the injectors. HELP

If this is anything like a Cavalier 3.1 or 2.8, check the coil packs. If they read out good, try the timing module underneath. If that checks okay, try the position sensor on the harmonic balancer. If that does not work. I don't know where else to go? Do you have a scan tool? are you getting any codes?
