We have a 2001 F-150 pickup. In general, it runs wonderfully, but the past month or so sometimes when I turn the key, the engine doesn’t turn over. Lights/radio, etc, come on, but it acts like I’ve just turned the key to the “on” position, rather than all the way to start the truck.
It has a new battery.
When it does turn over (which is 95% of the time, so far) it starts right up and runs great.
If it doesn’t start, I can make it start by turning it all the way back off and trying again. Today this took about 4 tries before it turned over.
What is likely to be the culprit, here?
