Answer
Hi Gabe:
Were thes parts put in for thge no start condition or did the problem occure after the parts were replaced? do you know if this car has injector pulse? meanjng the engine computer is running the injectors? unplg one injector and use a ECM safe test light or a noid light and crank the car the llamp should blink. If if will not blink and you have no spark on either coil I would look at the crank shaft position sensor. you can check the integrity of the crank sensor right at the ignition module the 2 wires to check are a purple wire and a yellow wire. if you have a digital ohm meter you should have between 800-1200 ohms or there about. If not then you either have a bad sensor or a bad wire(s) between the module and the snesor. The sensor is located in the block bye the oil filter. good luck :)
