Pull the air intake hose off the throttle body,spray starting fluid or carb cleaner into the tb opening,push the hose back onto the tb and try to start the truck.If it starts and runs for a few seconds then dies,youve got a No Fuel issue present. If it doesn't start at all,youve got a No Spark issue present. Just to rule out a engine flood condition,do this: Hold the gas pedal to the floor while attempting a startup.If the engine sounds like its fixing to start,release the pedal while holding the key in the start position. If it starts using this method, an engine flood condition is present.This is usually caused by a defective fuel pressure regulator,leaking injector or bad ect sensor.If youve got a no spark issue, start checking for spark at the coil,wires and plugs.If its a no fuel issue,listen for the fuel pump to run as soon as you turn the key on.If you hear nothing, check fuse #8,#9 & the fuel pump relay.The following link is a vehicle repair guide you can use.Click on the appropriate system (highlighted in orange text) you wanna view.Ex= routine maintenance, engine electrical,etc,etc.

If it cranks good but won't start, make sure battery has a full charge. Have a helper crank it while you check for spark at the plugs, gasoline engine. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. Let us know what you find? I can only help with testing. You have to do the testing.

well you can short over the starter and see if it starts. honestly i would remove the starter and take it to your local autozone. they will check it for free. also check the start solenoid. they have a tendency to cause the same effect.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.
SOURCE: Where is Fuel Relay for 2004 Dodge Ram 3500 Diesel Truck
it doesn't have a fuel pump relay it has a fuel pump control unit and it is located on the chassis back quarter drivers side near the tube cross member for chassis on top of chassis rail near bed mount. locate the rear springs front perch and it will be above that on top of rail.
hope this helps. good luck and please ask any question you have.

Hi, I will keep this short, but just a tip on the tester they use, I had one bench tested and it showed up it was good and the built in regulator was good also. Put it in the auto along with a $75 battery, and the discharge light was still on!!. So, I checked all of the charging circuit wiring finding nothing wrong, and put a rebuilt alternator on. Took care of my problem, the alternator was intermittent, sometimes charging when they checked it at Auto-Zone, but stopped putting out when I put it back on the car. I lived 16 miles from the auto store, so it was a pain going back and forth, plus the cost of gas!! I would change it out if you can at this time. I am sure this is what is going on if all looks good under the hood as far as wiring. Check to see if you have the 75 amp alternator fuse under hood also. It may be gone. Make sure the hot cable to the alternator and wiring plug is OK. Change it out and you will be good!
Sincerely,
