About three months ago my car just wouldn't start. I turned the key on and I can hear one click then nothing. I doesnt turn over. We have replaced the battery, changed the ignition switch, and have had the starter tested. All the light come on in the car and it seem's to be getting full power but it's not getting the messege to start. Oh hey when it first started a jump would work and it would cranked right up, the next to last time it wouldnt start, I turned the key on and held it for about 5-10 seconds and it just cranked right up. This time nothings helping!
