I have installed a bull dog remote starter on my 2001 grand am. everything starts fine but car wont shut off with the key.

Check for an aftermarket remote start and remove it. If no remote start check the battery cable at the starter to see if it's touching the "s" terminal on the starter. I hope this helps. Take care.

Take the starter back out but leave it connected. If it doesn't use a ground wire, make up a heavy wire and use that for ground.
When you hit the key, watch to see if the starter gear moves forward to engage an doesn't just spin. (it engages the flywheel when in place.) The engine isn't supposed to fire if it's not turning.

do you know if the remote is a after market or factory remote. have you tried to stick the key in the door lock and lock and unlock the door,and when start it. all new cars have have theif module in them ,and if is bypassed it will lock up

CAR NO START PROBLEMS:-----

There are two types of starters for Dodge, if you installed new battery, check to see if the remote start is to ignition module or starter solenoid, then make sure the circuit has not been closed-they go in series circuit!

The remote starter shuts down when you step on the brake?!? That's exactly what it's supposed to do. To operate a proper "takeover" from the remote starter the key must be turned to ignition on, not accessory.

your cars antitheft system is trying to prevent the car from being stolen so it is shutting it offf after it starts. go back over step by step you installation instructions make sure the ring around the ignition that comes with the remote starter is taped into the exact loacation it needs to be, or the cars own anti theft system will not notice it and will try to shut car off. its an anti theft feature. if this doesn't wotk you will not be able to use this remote starter. i ran into the same problem finally got it to work poperly.

Not an expert by any means, but I had a similar problem.
Everything was fine until one morning (it was a bit chilly out in my defense) I used my remote starter to warm up the car before leaving.
I forgot I had used the remote and hit the brake to shift into drive. Engine stopped (obviously with no keys in it!). I thought I could just put the keys in and go, but ignition would not catch.
I've actually made that mistake a few times before, but that day, for the first time ever, it prevented the engine from starting for a good 2 hrs.
Really was no solution. I just let it sit and kept trying every 30m or so with both the key and remote starter. The remote starter finally got it going again and this time I followed the instructions (put key in and turned to "On" position).
Since then, it has started up as usual.

did you try jumping it with another car.

Replce the Starter Relay in the Fuse Box under the Hood.
