Is that in the good or bad range?

 

Mkos,

I hope that you were reading resistance on a "K" ohms scale, meaning that your coil has a resistance of .757 K ohms, or 757 ohms. A good pickup should read between 500 and 1,500 ohms (0.500 - 1.500 K ohms). If your coil is actually 0.757 ohms, it's shorted and FUBAR.

Just to add to what Vader said, I spoke with a GM mechanic a few years ago, when I was dia-gging a ingnition problem...he says that the PU coil should be right at 800ohms, plus/minus 20 ohms...and he had no idea where the large range given, came from. Even my Helms says 500-1800 or somethiing like that.

Also, look under the plastic for any corroision, and the connector at the module, if you see any, replace it.

 

Nearly all of the ones I've measured were between 750 and 800 ohms, so .757 k (757 ohms) would be fairly typical. Usually they're either that, or short, or open, or intermittent.

If you are having ignition problems and suspect the pickup may be bad, try measuring it while you wiggle the wires around where they're fastened to the body of the coil. They often break where they hook up to the coil itself from vibration, and become intermittent. On cars with vacuum advance the symptom usually is something like misfiring either under heavy load, or under light load, but not the other, as the pickup moves and the wires flex from the change in vacuum.
