Since you know that you have spark and compression, the only thing missing is fuel. Sounds like a bad fuel injector. HTH. -Jim

When is the last time you changed the distributor cap? These things are notorious for having a cross firing or misfiring issue if you do not use a high quality cap.

steve - on the 6cylinder misfire the cause in my van 2004 was the boot to the spark plug clicked when i put on, but needed to shove all the way on and lock it on the plug it will click again and no more problems, i changed everything and 2 mecanics said spider just check the plug wire.
