won't start

yesterday the wife went out & started my 01 dodge ram 1500 5.2L, she forgot something inside the house. She turned off the truck & went inside. When she returned the truck would not start. It will turn over, it has fuel in the rails & spark at the plugs. in the shop manual it had me check the asd relay which was fine, then told me where & how to remove the cps sensor. I understand this tells the computer when to deliver the spark, is this my more likely culprit? Also the truck has no error codes
