Asked by Nov 22, 2015 at 03:15 PM about the 2004 Chevrolet Silverado 1500 Long Bed 2WD

Question type: Maintenance & Repair

2004 Silverado 4.3 V6...just died going down
the road without warning...no spark...already
replaced the ICM, distributor cap and rotor,
and tested the crank position sensor
(working fine)...im gettin a solid blue spark
coming out of the coil wire going into the
distributer, but no spark coming out of the
spark plug towers...tested the timing on the
rotor and thats not an issue (set cylinder 1 at
full compression, then checked that the rotor
was pointing at the #1 spark
post).....anybody have any ideas on what
this could be???
