how do I replace my fuel injectors

For a job like this I think you would be best off to buy yourself a Haynes manual for your Dodge. You should be able to get one at any parts store for around $26.

Remove the fuel pump relay-Start vehicle till it dies out. REmove battery positive cable- remove the EGR tube (4) 8mm bolts two on top of tube, and two at EGRvalve. Remove airbox and throttle cables from throttle body. Remove bolts holding the power steering fluid reservoir and remove upper intake plenum bolts, should be 8. Injectors are directly below remove the 4 bolts that hold the rail on and remove the tabs that from harness on injectors. Quick disconnect the fuel supply line- Remove fuel rail and injectors as one. Install is reverse of tear down.
