still domt know what engine it is...check grounds around thermostate..new rotor burned thru?check the White wire and Orange wire to the ignition module, both should have a 0-5 volt square wave sent to them by the Powertrain Control Module (PCM) to tell it when to fire the coils Read more: http://www.justanswer.com/chevy/3bhma-engine-will-not-start- 1996-chevy-s10-2-2-liter-no-spark.html#ixzz3jCbCvEli
