I have dodge ram 1500 v8 no start

SOURCE: need firing order on a 1996 dodge ram v8

The order should be stamped on your intake manifold right under the air cleaner.
My '97 1500, 5.2, 318 firing order is 1-8-4-3-6-5-7-2

Hope this helps

hi, you should find a serp. belt routing diagram on the cross member that supports your radiator. if not- disconnect neg batt terminal for safety. you'll need a long breaker bar metric. as most, if not all fasteners on your ram are in metric. cant remember right size socket, but just go through your metric set and "eyeball"it. once you have the proper socket-detention the belt by pulling breaker bar clockwise. remove old belt. it maybe useful to take a picture of how your old belt is routed with a camera equipped cell phone (if it is still on) so that if you get into trouble, you can look at the picture as a reference point. new serpentine belt install--insert new belt over the cooling fan route under crank pulley-over fan pulley, around p/s pump pulley,up and around a/c comp pulley, under idler pulley, over alternator pulley and finally around tensioner pulley. pull breaker bar clockwise to slip belt past and onto the tensioner pulley. release tension on tensioner. be sure to check tensioner indexing marks located on the tensioner arm this is to make sure the new belt is installed properly. reconnect neg batt cable to terminal-remove any hand tools from engine bay, start engine and observe belt operation. hope this helps!

If it's doesn't sound like it's your engine which i am thinking not. Check to see if there any heat shield that may have come lose, like the heat shield to the spark plug wire or heat sheild along the down pipe. 
Good luck and hope this was the rattling your taking about as it heats up it expands and tighten's up.
