while running along at WOT, engine died and threw serpentine belt. Reinstalled belt, Will not restart. Backfires through intake, tries to start but will not. The IAC muffler is missing, It must have sucked it in, I looked through IAC and hoses, did not find. Checked valve lash again, as I had just reset lash due to some rocker nuts backing off. (engine is 10hours on new long block) Lash was good. I replaced crankshaft pos sensor and checked for broken wires on sensor. Would IAC itself cause this? Any other thoughts?
