Wow 
Just so I'm straight on this. The engine won't run at all when in gear or just will run if you get past idle & low speed?
No offense but some of that stuff you replaced would have absolutely nothing to do with the problem you are having...
Also get a spark tester (not a screwdriver) & check the coil output up to 40kv

i know, some of the things we replaced were bad when we bought the truck. we got it from an old man & when it gave him problems his solution was to unplug the sencer that he thought would have been causing the problem. thanx for your help but simply by chance we figured out the problem today. we had replaced the fuel pump about a month ago when it went out so today we took it back out to c if we had knocked something apart or had a line crimped when we took out the pump the new sock somehow desolved & the pieces sucked up inside the pump to cause a blockage. dont ask me how it happened but we cleaned it out replaced the sock & it runs fine now. thanx agian for your thoughts have a great night
