Im still having troble with My pathy,  and while checking spark the
other day,  i used an induction timing light to check spark output
from coil.      I seemed to notice more than one flash per rev of
engine on some cyls......I even made sure that the wires were
separate.......Can a coil screw up in this way?  Or was the testing
proocedure likely to fail as a result of using the gun?  My Truck
still wont run and the head gaskets are ok I think     oil is clean
and so is anti freeze   nothing seems wrong       yet it sputters and
chokes and geneally wont run/////

PS 87 Pathy   that was running fine one day and then basically not at
all the next..

               Thanks In advance
