'03 V6 Coupe - it cranks and cranks, but it won't start. Haven't had any other issues with it other than a transmission replacement about 5,000 miles ago for the recall problem.

Tried jumping it of course and didn't work, the battery tests fine. Could it be the spark plugs or timing belt? I have no idea, obviously.

Any help would be much appreciated!

 

something like this just happened to me and a friend this weekend. He has a 300C, and we were doing neon rods under it and we drilled through a bundle of wires and the car didnt start. What happened was that we grounded the car and as a safty precaution the computer wouldnt let the car start. Perhaps somehow this has happened to you

 

Is the immobilizer light on solid or is it flashing? (with the key on)

 

The immobilizer light is flashing when the key is on.

 

I'm assuming that means there's either something wrong with my key or with the ignition module?
