No start problem
 

My son has a 94 S10 blazer with an unusual problem we have been chasing since last summer. Whenever the outside temp get over 80 degrees and he has driven for about 15 miles then shuts the truck down it won't re-start until it has cooled down for about an hour. When it won't start the temp guage is pegged but everthing is looks normal, we have replaced the fuel pump, injector, temp sensor. If this was a carbruated truck I would suspect the fuel was perking but since it is injected I'm lost. any help would be greatly appreciated.

my bes guess would be the temp sensor but if you replaced that id propbly chek the wires to it or maybe have the computer checked if you havent yet having the dealership hook it up to a diagnostic machine sounds like a good idea.

actualy isnt there a air intake temp sensor are you sure you replaced the right one? or replaced with the right part?
