thanks for the help in advance. sorry its an 02 LS. 4.3 vortec. hot to the coil but getting no fire at all!!!!! all new coil,plugs,wires, cap. this after doing the heads!!!!

 

well I finally got my hands on a computer after looking all over the engine over and over for 2 whole days. It was a broken wire on the Crankshaft position sensor!!!!! one snapped wire kept the entire system shut down!!!!! But between Haynes and the puter I got it purring like a vortec kitten!!!
