My money is on connector that ties ignition switch wiring as it exits column to dash wiring harness loom. Simple to check out at with a test light at starter relay as ignition switch Is turned to 'start' position. There are 6 main wires in this connector,,,one of which feeds current from ignition switch to starter at the underhood relay.

Male pins or female receptacles often lose their required snug fit at this connector.

Remote possibility that ignition switch itself is bad.

Can also test by running jumper wire from battery positive to the wire tab at relay that sends signal to starter solenoid. If cranks, either above connector is bad or firewall connector is.

If no crank, is solenoid or starter itself.

Doubt very much that a defective battery would cause zero starter response if headlights illuminate ok.

It was a very weak spark. I will pull the starter out and have it bench tested. The last time I did that the starter bench tested OK but did not turn the engine when i reinstalled it. So I bought a new one and that solved the problem. I do not like doing the work twice. I am a little skeptical of auto stores saying the part tests OK then It does not work in the car. The battery obviously is a easy out and in deal.

If your going to replace the starter go with a mini. Easier to work with and turns over faster and stronger.

If i had an extra known good battery I would have put that one in the car and try starting it. I did put a socket and breaker bar on the crank bolt and the engine does move freely. This morning I went out and tried to turn the head lights on and nothing. The dome light does work. I put the battery charger back on and it is now recharging. Seems the battery is loosing its charge over night. I am going to take the battery back to Sam's Club and have them load test it. The battery still has a couple of years pro rated warranty. I will probably buy a new battery and eliminate one of the variables. The starter looks new and I checked my records and I only have about 100 miles on the starter in the last 4 years. Sorry for the long blog.

Went to Sam's club this morning. They tested the battery and said it had a dead cell. So they gave me a new battery. I am going to install it after lunch. Hopefully this will do the trick.
