I have a 2004 crossfire and it won't start battery is good 100% fully charged. It won't crank, click, no lights turn on and I've had the battery checked and it's fine. What could it be?

I'm sorry if this is late but get you crankshaft position sensor and your camshaft position sensor checked. These sensors are probably bad.

I had issued with key batteries. Does anyone know of a Los Angeles/Santa Monica independent Crossfire mechanic?

YouTube, "Chrysler crossfire mystery no start". A fella does a video showing some soldering on a board under the hood. I did it, and haven't had the problem since.

try checking the coil fuse in the fuse box under hood drivers side

Ground wire is corroded you see it at the left side under the car. you need to replased
