Is the distributor rotor turning? Is the coil output high enough to get through the distributor rotor/cap air gap?

The coil on that year should be able to make a bright blue spark at least a half of an inch long. If you are good at it you can have someone crank the engine over while you hold the coil wire from the distributor close to the engine block and watch the color of the spark but be careful, if you don't do it right and the spark uses you as the ground path welll lets just say it will really curl your hair.

It only sparks about a 1/4 of a inch and its kinda orange and blue

Sounds a little weak. Do you have another coil?

Let's try one more test. now remove the wire from the coil and have someone crank it over, the spark should jump out of the tower and flash to the case of the coil, if it won't do that then yes replace the coil, if it does flash over then the coil wire is bad, Have you ever replaced the ignition wires?

Might be a good idea to do that. Did you do the last test?

I have a 2000 Dodge Ram 1500 4x4 5.9L and replaced spark plugs, distributor cap, rotor, and still had a miss problem going on when i floored it. I noticed every time it rained it got worse and eventually the engine died out on me all together driving home from work oneday about a block from my house. My neighbor and I got the truck to my drive way where we started checking for spark using the screw driver to frame method while cranking over the engine and had nothing on the spark plug wires coming from the distributor. We then tested using the same method using the ignition coil wire and had a light pink to orange arc. Ran same test at the coil itself to rule out faulty wire with same result. Once I took off the ignition coil it self, I then checked the resistance through the coil using an ohm meter and compared the results to my handy shop manual. The coil was out of tolerance reading through the primary and completely dead through the secondary... I also had a big crack in the bottom of the ignition coil where water and moisture could have been causing my problem when it rained. Once I replaced the coil, the truck fired up immediately. I took the truck around the block flooring it with absolutely no miss at all. I had been having this miss problem for a very long time and learned something through the process. As I pulled the truck in the driveway from my road test, my neighbor says "NOW THATS THE BIGGEST SHIT EATEN GRINN IF I EVER SAW ONE"... Lol... Thought I would pass this info. onto the poor unfortunate fools dealing with the same problem.

Yep....weak coil is pretty common. More common than a distributor failure...cause the coil has to repeatedly ramp up and fire energy so quickly...it's doing a lot of work!
