Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Most of the time this is caused by a failing ignition switch. If the switch does not turn all of the way off then this will occur. It can also be a starter relay, but that is not as common. I hope this helps. Please let me know if I can be of further assistance.
Thanks for getting back with me. If you need any further help please let me know.
When you installed the ignition switch were all of the teeth on the switch aligned?
Make sure that the battery is fully charged and that the connections at the cables are clean and tight. If it persists it can be a problem with the body control module.
