i just purchased a mercury sable, i know this is a ford forum but it is made by ford and all. a couple days ago my starter went, got it replaced and the car has been running great. till today, when i decided to use my automatic car starter, the car started but the starter would not stop engaging, even after i hit the brake which should auto shut off everything as the keys were not in the ignition.
guess my question is: did the automatic car starter cause this issue? could the starter not have dis-engaged because the mechanic that put the new starter in didn't hook it up correctly to communicate with my automatic car starter?

also, the only way i could get the starter to stop was to unplug the battery, if i plugged the battery back in, boom the car is trying to turn itself on.
any insight would be greatly appreciated!

 

If the car started fine UNTIL you used the auto starter, I would suspect something in the automatic starting system is not right. You might want to check the remote out first.
