Car won't start electrical problem

Car wouldn't start tonight, turned the key, the dash lights turned off heard one tick and that's it. After a few minutes I could do it again but the lights didn't come back on right away. The last maybe 6-8 months the theft light would randomly come on once in a while but not effect anything. Could it be a bad ground, starter? I read something about a bad chip in my key? Any help would be great

I have the same problem. Power just seems to cut off out of nowhere. Try wiggling either the postive or negative on the battery, that seems to fix it in my case. Pretty much it just isnt a sturdy connection to the battery

Sounds like for whatever reason you don't have enough juice. Check all connections, power and ground, and if everything is snug check the battery and alternator. When you aren't getting enough power it can cause the theft system to act up like that; mine did when my battery was on the way out.

I had a similar problem with my 02 gt. It turned out to be the negative battery terminal corroding. The positive terminal soon followed. With how thin the terminals are, if you dont check them often they will corrode to nothing. The same thing happened to my 98 v6.

your battery is weak or your connections are lose or corroded

I'm guess it was the connections, I cleaned some wires up tightened the connections and it started right up. Maybe it's time for a new battery as well, I tested both the battery and alternator and they were both fine though

Maybe invest in some brass terminals? I use them on all my cars and they're great. Hate the flimsy factory ones.

I just got those cheap terminals from advance that are a lot thicker than factory. All you have to do is remove the stock terminal and clamp the new one on. They were a few bucks a piece but they do the job well. Its been a while with no problems, though they arent the prettiest.

Best thing I've found to do with a battery is coat the terminals and clamps with a thin layer of Vaseline. It won't corrode at all after that.

I use anti-corrosive grease. I use that stuff on all electrical connections I mess with. Works great.
