stumped! Won't start!

I have a 98 chevy silverado 4x4. Thought the starter was bad because there was some grinding going on. Put new starter on and it did the samething. Flywheel is ok. It ran fine the last time i drove it. Then it sit for week and all this started. The power steering pump was acting up the last time i drove. Could this be going bad and cause the grinding I'm hereing. When I try to start It will turn overgood a little bit then start acting like someting is binding, keeping the truck from starting. I am getting good fire at the plugs and it has a new fuel pump. I know it sounds like i'm mumbling, but i'm lost on this one.

you should post this in the C/K forum, but anyway, what type tranny, eng etc. Need a little more info. Have u tried it with the serp belt off?

I tried that yesterday, and it started. Put belt back on and it started, After about 4 or 5 times of starting it would drag again but it would start. The motor has picked up a miss. It had a small backfire. Now i'm starting to wonder if it is the dist. or timing chain. It is a 5.7L not sure about the tranny it has overdrive, the truck is a Z71. One other thing , about a wk. before i stopped driving it we had 27" of snow. A friend got his truck stuck and I pulled it out. While I was doing this, it hit the rev limiter a couple of times?

It is fixed. It was the dist. cap.
