Have a '96 LeSabre with a missing problem that does not show up on
the computer. I suspect it may be one of the coils. (Pretty confident at
this point that it is not plugs or wires). Does anyone know of a way to
check these coils ? To arbitraily replace them is not a great option,
would like to be sure.
TIA ! ! !
You can swap a coil with another on the ignition module. If the no-spark
problem follows the coil, then it's the coil. If it stays in the same spot
on the module with the coils swapped, then it's likely the module.
Ignition modules can be tested for free at Autozone.
I used this method to find the defective coil on my '93 Trans Sport with
Take a timing light and attach it to each of the ignition cables. Press
the trigger. When the light flashes erratically, you've found the cable
that is attached to the defective ignition coil. (Be sure to use a timing
light with an inductive pickup, not an in-line pickup.)
