When i hook up the battery the car turns on by itself, like the fuel pump and interior, when i actually start it, the engine won't stop i have to unplug the ecu for it to quit runing(kinda scary when you take your key out and your car is still running:eek3: ). The cd player works ok though(besides it doesn't play cds)when i put my car in the on position is the cd player turns on like its supposed to be.

I don't get it. I've checked my ignition switch and it's fine so i can rule that out.
i hope you guys can help out....thanks
