So my awesome Automatic 500 just gave up. I unlocked my car with the key fob, loaded up my tool and went and parked the work truck. Come back to the car and turn the key and nothing. When the key is released I get a flashing P and the beeping sound and of course the key is locked in the ignition. I googled how to remove the key and after taking apart the steering column I got the key out. The shifter is stuck in Park, I can over ride it and put the car in any gear I want. I pulled the battery and tray to look at the bushing on the end of the cable but it is there. The actual transmission shifts along with the cable. I also disconnected the transmission computer and made sure the plug wasn't corroded and hooked it back up. I also replaced the brake switch as it was cheap and easy to replace. The car will not lock and unlock with the key fob, nor will the back hatch open. I bought new a new battery for the key fob just as a precaution.
I'm guessing the car doesn't know it is in Park. Maybe the transmission computer? Any ideas would be appreciated!
Thanks!

Hi everyone, I have CEL since July and pulled the following codes. When I started the car cold, the idle was rough and it would smooth out after a few minutes when the car got warm.


Since then I have replaced the following myself and the idle is now pretty smooth even when I start the car cold
1. Upstream o2 sensor
2. Downstream o2 sensor
3. Vapor Canister Purge Valve Solenoid
4. Vapor leak detection pump


I replaced spark plugs and coil pack earlier this year.


However, CEL still on. what can be the cause? I tried to clear code

Appreciate your feedback. thanks!

So two months ago, I had a couple of times when I went to start it and there was a short delay before it started. I drove the Abarth to work and when I went to leave. No start, key in, fuel pump primed, turned key, and no starter motion. I let the car sit at work a few days and went back with some friends to try and push start it. But on a whim I tried the key and started right up, so I drove it home. It has been fine ever since. Started every time I've tried since. (though admittedly, I haven't been driving it a whole lot since the incident. I got spooked and bought a new car after it left me stranded)

Today, the mysterious starting problem is back. I started the Abarth up, moved it, and let it idle for 15-20min to warm up (because I haven't been driving it much). Turned it off and started it a couple of times with no problem.

Cleaned the interior a bit and when I went to move it back to it's parking spot an hour plus later. It started, but there was a delay again. Like a 1 second delay when turning the key and it starting. I turned it off and got the same 1 second delay starting. I moved the car, turned it off and tried to start it again and got NOTHING from the starter. I tried 3-4 more times more and on the 4th attempt with the key turned and about 7-8 seconds of holding it turned, it started.

I've already swapped the battery. Changed the battery in the fob. Cleaned the ground strap under the battery. (I have a new strap but I didn't put it on as the car was starting just fine.)
What is going on?!?! Is the starter going? Heat soak? The starter is so buried I haven't had a chance to put a probe on the ignition wire yet.

Need help.
