1996 b2500 3.9v6 missing through range
I have a 96 b2500 with the 3.9 v6 and it has been missing through range. It goes through distributor caps & rotors every couple of months then that seems to be a temporary cure. Is there a way to set the timing because it looks like the distributor is fixed and not able to rotate to set the timing. I have replaced the plugs and wires. I was thinking of going with the accel coil and accel cap & rotor, anyone have any suggestions, thanks.

Your obviously aware that the cap and rotor are not your problem, just a symptom. Even the poorest quality one should last longer that you claim.I don't know why your cap and rotor fail so prematurely, regularly.
After reading a lot of posts from those more knowledgeable than myself, I'm switching to a dist. cap with the brass/ copper terminals, even though I've had no problem with my aluminum ones. I also have had the Accel copper core wires in my '89 318 for over 2 years now but am going to replace them soon with something different. The S.P. boots are brittle crap. With no di electric grease in them they fuse to the plug, with itand they pop off the plug. These resistance free wires also wreak havoc with my AM radio reception, and cause an annoyinghum with my MP3 or FM.
Despite one mechanic years ago reccommending accel wires to me, I have heard nothing good about their products lately, and my current wires ensure I will never buy their products again.
Hope you get it sorted

There is no way to set the timing as it is controlled by the PCM. Your problem could be due to the distributor not being lined up correctly, in which case the spark is jumping before the rotor is lined up with the tower on the cap, resulting in a lot of burning.
1. Position the No. 1 cylinder at TDC on the compression stroke. The rotor should be pointing at the #1 tower of the cap. If it's 180 degrees off you'll have to rotate the engine one full turn and line up the timing marks again.
2. On some engines the camshaft position sensor has a "CYL NO. 1" mark while others have a notch in the distributor housing.
3. The center of the rotor should be lined up with the mark or notch. If it's not, loosen the bolt on the clamp at the base of the distributor and rotate the distributor until the rotorlines up with the mark or notch and tighten the clamp back down.
