it just stopped, i turn the ignition on but nothing happens, car does not turnover. the lights on the dashboard and radio turn on, the headlights work. i used cables on the battery even got a new battery. got under the car used a screwdriver on the starter to start it, it would turnover the engine but quickly die. next took out the starter had it checked . it worked fine. just for the heck of it, i changed the fuel filter. still nothing. i'm thinking maybe it's the battery wires, or some computer chip/ i also checked the fuses but nothing . i'm really trying to find out what it is. if i could afford a better car i would get one . can someone give me any advice or pearls of wisdom on how to fix this? thanks
