ok heres the problem i have a 1988 chrysler fifth avenue and i cant get the coil to spark i have replaced the coil, the ballast resistor, voltage regulator, the computer, the battery and i have checked all the wires but it still wont spark, but it sparks when you turn the key on but when you try to start it nothing happens. the engine turns over and it gets fuel but thats all it does. i need help!!!!!!

Maybe something's wrong with your key switch?
