2002 5.9 magnum crank no start. HELP!!

[Ghostjr1]

Already people of the interwebs. Im at a complete loss here. I have a 2002 ram 1500 with a 5.9 magnum with a auto trans. Im currently havin an issue where the truck cranks but wont starts. It acts like it wants to it starts junpin and stuff but wont start. Ive replaced the IAC sensor it fixed the problem for about 2 weeks and has started again. The CEL is on for thermostat stuck open, and onmy Matco scanner the Dodge Enhanced says P0100 which is for the MAF sensor but i thought these dont have a MAF. Can someone help please. Btw the truck only has 102,000 miles.
