My 1991 s10 4.3L wont get any spark at the plgs
I had a lifter leak down and knew it was a matter of time b4 all of em had to be changed, so i put all new ones bk in it. While i had it apart i had the heads resurfaced & new valve guides, valve seals>
all i can think of is you missed a plug in ,recheck the wireing.
