Check out the plug for the crankshaft position sensor if it's getting power you should hear the fuel pump run but I would check the plug it should be a 3 wire plug 12v power, signal, ground on the signal make sure it pulls to ground check the pins on the plug for oil

Cold start open loop pcm is not in command, therefore rule out sensors,the ignition module makes adjustments untill your pcm goes to close loop.
