Parked my car last night now it cranks over but won't fire. I turn the key to the on position none of the dash warning lights come on except the break light and the anti theft flashing and the dinger bell, the fuel and amp gauges don't move and I don't hear the new fuel pump make any kind of operational noise. I have two different keys and tried both sets will not start. I'm thinking maybe the ignition switch is bad do to the dash lights not working or the transponder bad and not reading the chip in my keys tripping the anti theft system? What would be the route any of you guys would take?

Hi,

If the anti-theft is preventing the engine from starting, the lights would still turn on. Therefore, I suspect we lost power at some point.

Do me a favor. Let's start by testing a couple of fuses. In the underhood fuse box, there are two to check. See pic 1. In addition to checking the fuse, confirm there is power to it. Here is a link you may find helpful:

Next, I want you to locate the inertia switch. It is located in the trunk, left side. It shuts power to the fuel pump if there is an accident. Check and reset it and see if that changes what you are experiencing.

Do this and let me know what you find.

Merry Christmas.

Joe
