I have a 98 Plymouth Breeze Expresso 2.4L /AT with 315k miles and crank but no start situation. Timing is dead on and the cam shafts are rotating. I have measured 12 volts to the coil and have switching signals from the ECM on each coil bank during cranking but no spark to the spark plugs using a HEI plug tester. I have verified voltage and signals using a digital multi-meter and LED circuit tester I have replaced the crank sensor(3), cam sensor, coil pack (3), spark plug wires, ASD and Start relays, and the ECM and I also have 50 lbs of fuel pressure during cranking. What am I missing or is my car defying the laws of automotive science.
