2003 Grand Am GT

Asked by KKam Apr 01, 2018 at 11:03 PM about the 2003 Pontiac Grand Am GT

Question type: Maintenance & Repair

My car is bipolar, after a 8hr shift I came to drive home but
it wouldn’t start. It always cranked and turn over, and we
could here the fuel pump so I didn’t know what it could
be. My mom & bestfriend meet me to give me a jump but
nothing. After a day & a half it sat at the train station, I
called a tow truck to tow my car home, but he mentioned
he wanted to play around with the car before loading it.
Guessing because this problem had just started. He
mentioned the day before when we tried cranking it, we
may have killed the battery so he went to the truck and
grabbed a portable charger of some sort and charged my
battery. Little over 10mins or so he attempted to start my
car after charging and everything was cool. I was able to
get gas, go to the bank, and home with no problems.
Crank & start on first start like any other time.  I eventually
came home, then left out about 1hr or 2 after to head to
Walmart, my car seemed perfectly normal, I even made it
home! After sitting for about 8hrs I came to my car to start
it and nothing!! It would crank and turn over but never
start! I eventually found a  mechanic to diagnose my car,
he mentioned my starter was new, and said it could
possibly be a faulty ignition. And the I had low fuel
pressure?? So we change the ignition, but when in the
dash he noticed my wires have been cut and not attached
back probably. They all were rapped in electrical tape
careless almost. He goes to fiddle in the dash and turns
the key and boom out of no where my car had started. I
thought it was best to drive to the gas station, to let me
car run a little so that’s what I did. After making it home,
the next morning my car yet again wouldn’t start. It’s not
my battery, starter, transmission, or even alternator. I
NEED HELP possibly failing fuel pump? Please respond!!

I have 2009 Pontiac Gt and it won't start. I had a key with the little sensor on it but I ended up with a regular key and every since the car want start, please help me figure it out. Should I get a new ignition switch with a new chip or can I bypass it altogether.

Did you have the ignition changed when they did the recall? I did & about a month after my car would do the exact same thing. The anti theft isn't used to the new key, or at least that's what I think. Anyway, I had to reset my car. If that makes sense. What I did was put my key in my ignition, then turn it to acc. Then I just let it sit for about 20 mins. That's when I turned the key to the off position & then it started it. She fired right up. This happened for the first time about a yr ago. It's done this 3 times since. If this doesn't work maybe look into a starter or even an alternator. Hope this helps.

If the security light is blinking you have to reset the computer before it will start. Turn the key to the acc and leave it on for 10 mins or until the security light goes off. Then you can turn the key off and back on and it should start. There is a security system (anti-theft) has an error. All 6 years that this car was made have the same or will have it. I have a 01 grand am se 4cyl and an 03 grand am gt. Both have had this problem. It's annoying but can be put up with lol
