Thanks to all who replied with help for my truck. The cat turned out to be the problem. We sawed it off and the truck fired right up unfortunately that was after we spent all afternoon trying different things right down to tearing the front cover down to check timing marks. All I have to do now is gut the converter and start reassembly when my new parts get here. Im going to change the timing set along with the lifters and hopefully it will go for another 200k. Thanks again for all the advise.

 

thank you for coming back and telling us what the problem was... so so many people don't.
