Bigger than MH370 Mystery...MY TAHOE!

[350VortecSSCT]

Well I was driving on the highway, all the sudden I lose, power, particles shoot out of my exhaust, cats went bad...I disconnected the collector pipe and try to turn truck over...and it won't! How would it be a bad computer? or bad fuel? I AM SO LOST!

Particles out the exhaust is always a good sign. Can you turn the engine over with a braker bar or something?

LOL I want to hear how it's an O2 or temp sensor.

Sorry guys been busy on aircraft engine work lately. 350, can you describe the particles to clarify what you saw come out? and as I understand it you disconnected the y pie assembly that had the cats on them from the exhaust manifold? when you say it won't turn over do you mean the starter will not rotate the engine but does engage or does not engage or engine turns but will not attempt to run or does attempt but will not succeed. the term "engine won't turn over" is to vague and really needs to go away.
