The pickups are NEAR indestructable. However, newer ignition systems SOMETIMES have such a short pulse duration that they won't trigger SOME timing lights. Try having the pickup NEAR the plug and then near the coil and see if you get any improvement with either position.
Else, there is probably a degraded component in the units.
