Hi,
was running errands the other day all over town and stopped at a friends house for a little while. Got back in my 2002 TL and the car did not even crank after multiple attempts. Had to leave it there for a couple hours until I came back trying to diagnose it. While I was under the steering column I tapped on what I assumed to be the ignition/starter relay with my phone and it worked? Got it back home and removed what I tapped on and it turned out to be the turn signal relay. I repeatedly started the car on and off again and out of the 8-9 or so times that I did, it failed once. I have no idea what is causing this, really need help because I don't want it to fail when I'm not in town.

Thanks

 

Starter. Same thing happened to me a few years ago. Carry a hammer/pipe n your trunk. Next time it happens, hammer the side of the starter. It gets the starter off the ‘dead spot’ and it will start. Old Chevy trick.

 

Sounds simple enough, thank you
