very frustrating.

Is the battery good and charged up? Have you checked the battery terminals for corrosion and have you cleaned and tightened the connections? Checked for power at the starter? Is there a security light on in the dash?

The battery is brand new and terminals are clean. Replaced the starter last month with a brand new starter. However, the security light flashes.

Everything has power. Lights come on, windows roll down, radio turns on ect.. It just won't start. Have a half tank of over priced premium gas so im kinda annoyed at it not starting having just came back from the gas station an hr ago.

I have one that does the same thing is the starting SIM annoyed on the fire wall little circle Black piece with 2 Nubs coming out Put your screwdriver in between them together it To gather should start
