Cranks but doesn't start using the key. Starts when using a remote starter switch.

What 67Dart said.

Not sure what Professor Fate's point is...

How about a picture? While the illustration may not be exactly what you have under your hood, you can SEE how ign1 and ign2 are wired, and how 67Dart's post applies. It seems hard to visualize for some folks but when you understand that power can go through the resistor in EITHER direction, it is easy to understand how the two key positions (start/run) work.

Thanks!

THAT DIAGRAM (and there are similar ones) is SOMEWHAT MISLEADING.

At upper right where it says "start position of ignition switch" it is important to realize that they are talking about the IGN2 contact, and that it is "live" in the start position. There has been confusion in the past about older cars converted to breakerless, thinking, incorrectly, that that connection comes from the "start" terminal of the switch.

WHY IS that important? Because you do not want to interconnect the two. The "start" terminal and the IGN2 terminal of the switch are isolated to prevent feedback into the starter relay.

And yeh. The box is powered in "start" by current flowing backwards through the ballast, from IGN2 to the coil terminal, through the ballast, and back into the box.
