My car won’t start, when I go to turn on the car (push button start) the engine light starts to blink and he immobilizer light appears, the relays under the hood also start ticking at the same rate the engine light flashes. I’ve tried a new car battery, fob battery, new terminals for the battery, checked to make sure all connections were tight and checked the fuses and it still won’t seem to start. Does anyone know what could be wrong ? I’m starting to think antenna module or either the brake or clutch switch.

1. No where in your post do you mention checking battery voltage.

2. When you push that button, it sounds distinctly like a low battery and a starter getting low juice.

Check your voltages and report back.

emebarak, why not start another thread stating your problem and giving, as I suggested to the OP here, the voltages and where measured.

Stating for instance, the *Battery in the car is good* tells us nothing really.

I’m having the exact same problem with my 2010 3.8 it starts ticking by th ecu main relay\fuse by the fuse box closest to the battery. And engine light ticks. When I start my car it sounds like a bad starter with a damaged flywheelD6C69BED-9372-443E-8A57-A9753A4A51E8.jpegF338CF17-2359-4041-B643-F91E27D9AA84.jpeg

I had the same problem with my 2010 380 GT a year ago. After a few attempts to start it with a jumper box, even the dash displays died. The tow-truck operator initially insisted I had a bad battery, but the battery was only a year old and in good condition, so I wasn’t convinced! The culprit was the grounding strap, which is not the usual flexible cable, but a set of rigid, connected segments. Mine had corroded at an attachment point under the transmission. $120 to diagnose, $35 to replace. Presumably a more frequent problem here in the northeastern U.S., where they salt the roads in winter.

Hey thanks for the reply!!! I live in the Caribbean so salt is in the air. The first problem I had before this all went downhill was because of a bad ground the black wire that connects to the ground on the battery. It was very loose. So loose you could slide it off the ground with your hands. Maybe that short Circuit My car. I ordered a brand new pdm and ecu and will program them tomorrow and will give that a try. Thanks for your reply !!! Will add to list of things to check. 👍🏽👍🏽👍🏽
