i decided to chane the cap and rotor and put the new on with correct firing order which i have checked 15 times and the car will not crank. i get spark but the spark is not consistent,voltage to the coil the module is brand new and resistance in the coil is good. the car has an e cam in it. i tried just putting the wires on the cap in no special oreder and the car sounded like it almost wants to start. i musta have the firing order wrong but i have changed caps on all kinds of 5.0 mustangs. is the firing oreder diffrent for an e cam. something this simple is driving me up the wall
