Hi! Here’s the deal. My PT Cruiser was starting fine two weeks ago, but after a frigid cold spell, it wouldn’t start, even when hooked up to jumper cables. It turned over fine, but wouldn’t start.
I checked and replaced the spark plugs and cleaned out the wells of some gunk, which I thought would solve the problem. When it didn’t, we moved it into the garage to warm it up. Once it had warmed up a bit, we tried to start it with no success. At that point, it still turned over.
I thought maybe I’d messed up the spark plug replacement, so I pulled off the manifold again and checked them. I cleaned out the insides of the spark plug wires, and then put everything back into place and tried to start it. That’s when it stopped turning over.
We tried hooking up a full new battery, but it made no difference. There’s a hum but no clicking or anything. My idea was that the starter motor is trying to start but there’s too much resistance, but I don’t know for sure. What else could the issue be and how do I fix it?
If you need more details, my car is a 2006 Chrysler PT Cruiser Limited Edition without a turbocharged engine. Thank you!
