2004 dodge hemi WONT START???????????

First does it crank, if it does then check to see if the fuel injectors are getting fuel.....could be a fuel pump...

second....if there is nothing when you turn the key and the battery is good and the starter was replaced...it could be a bad ground.....thats the ground coming off your battery and goes to your chassis of the car.........let me know how you make out.

Basic testing needed. Spark at the plugs? Fuel pressure correct?

the first thing to check is the temperature sender to computer output.
if thevco.mputer thinkd its 80 degrees when in facrlt its 20 deg. outside...the fuel mixture will be two lean.
an easy test...squirt a spray of carb cleaner into the intake...replace inletvhosre...try to start ....if it fires right up....means mixtures too lean....check for cracked vacuum hoses..previously mentioned temp sender signal.....and the simple things..
how old are spark plugs...and change fuel filter yearly...

suggest that you bled the system including the pump and get all the air out.

Did you check the pump relay ?

i need to change my oxigenpipe for a dodge 04 1500 but i dont now where to find it

Check your idle air control motor. It isn't starting because your not getting air going into the motor, when you press the accelerator it allows air to enter so the engine starts.

Sounds like a coil problem, I don't know how the ignition systems work in the hemi's but your coil could be overheating.

this is your camshaft pos. sensor

You probably spun a main bearing
