So my car starts fine when I turn on the ignition and run the starter with a remote start switch, but not when the key turns powers the starter? This makes me suspect that the ignition switch is turning off the ignition while in the crank position. Is this a common failure point of these switches? or should I be looking somewhere else?

Thanks Emory. Not sure why that happens but the consensus seems to lean towards a coil issue and the symptoms are indicative of a weak spark/ coil issue.
Think I will jumper the coil on the next cool morning and give it a try I am not 100% confident in the CD. This one went back shortly after install for a repair. Seems fine but… |
