Vehicle had an intermittent starting problem when the theft lamp would blink quickly. Used to have friend jump car which would override the problem and allow starting. Car would start again as long as I didn't let it cool off. Now, jump doesn't help either.Now lamp flashes whenever I try to start the car. I need this car for work, and am between a rock and a hard place. HELP!!!!!!

car wont start.Replaced the starter, the battery, starter relay, and the ignition switch, ran for 1 hour and then wont start again.

Theft light blinks rapidly. Key will not start car. Turned key on for 10 minutes and no start and/or codes. Have used this same key for years. Also tried spare key.
