Default 2002 Dodge 5.9 gas

2002 Dodge 1500 5.9 fires but will not start. Before I accidentally erased the codes I remember 301,302,303 and 455. There is pressure in the fuel rail but seems weak, I have no way to test it. Anyone know where to start?

Recheck the codes. Those will tell you the hard faults that still exist and maybe point you in the right direction...

the first codes are misfires and are meaningless. The P0455 code is a large evaporater canister leak, generally seen with a loose gas cap. Also if a hose is off that may allow vacuum in the manifold to be weakened to the point of scrambling the brain with errors.
Try removing the battery hot wire for 10 minutes and then hook up and try again.

Well, I went to HF and bought a fuel pump tester, got back home and hooked it up, set the gauge so I could see it from the cab, turned the key and it started on the first round and stayed running with 50# pressure. Now it starts and runs just fine and no trouble codes at all. What do we think of that?

Gerry is on the right track, did you just fill up? and it would not start? The VW just did that. There is a purge valve in there somewhere that is sticking and confusing things I would venture a guess. I got gas and sat down and it just cranked and cranked, I put the gas pedal to the floor and it started right up. Started fine till we got gas again, same song and dance. changed the purge valve and has not missed a beat.

The mass vacuum leak code is the one you have with the leak or bad purge valve.

And the one for your truck looks very similar to the one for my VW

Default common 99-02 dodge no start and rough idle and bad fuel milage

Replace the fuel filter if it is running now it will take a few turns of the key on and off for 10 second intervals, let it run and check pressure at fuel rail
if you checked the fuel pressure at the fuel line in back of filter and got 50 psi your good there. 45 to 55 so your with in range

if your below 20 psi at fuel rail replace the fuel pressure regulator if you have one inline on fuel rail cant remember but some are attached to the pump in the tank.

also if you have mass air flow sensor disconnect battery neg. cable pull mass airflow sensor and clean it only with mass airflow cleaner .

also pull the breather tub off the throttle body look in at the butterfly valve
if its blackened carbon build up pull it and clean it only with throttle body
cleaner and a soft brush till its clean almost new clean.....
and it wont hurt to clean the IAC ..Idle Air Control... usually attached to the
throttle body.

Never use carb cleaner on throttle body it is too harsh on the coating of the throttle body

Hope this helps

You can learn a lot about evap systems on YouTube. Wells automotive has some very good lessons on how they work and how to troubleshoot.

Of course like Gerry said, may have been a loose gas cap, and the code may not come back. The engine computer will run a test periodically to make sure the evap system is working and not allowing evil gasoline vapor escape.
