I was working on my truck yesterday (2001 Ford Explorer sport trac) trying to find a leak in the AC vacuum supply line. I removed the air cleaner housing & outlet tube, unplugged MAF and crankcase ventilation tube (to get to the reservoir globe). I found and fixed a leak in the AC supply line. When I had the air cleaner housing off yesterday, I had run the car for a few min to check if there was vacuum in the AC supply lines. The car started running rough then, so I shut it off. Put everything back together, but now the engine won't start. Battery and Alt are new. Oddest thing. Can't figure out what I might have done. Any ideas?

Obviously, double check everything that you touched. Look at all the polugs and pull them off to see if any of the blades got bent over. Also make sure all hoses are reattached and not sucking air anywhere.

Ok I was suspicious that the crankcase breather hose seemed to fit on loosely (to both the crankcase and the air cleaner outlet tube). Does this need to be a tight seal?

Reasonably tight but it won'tcause a "no start" if it's just a little loose.
