Getting no fire to the spark plugs. I have changed two coil packs and spark plugs along with the crankshaft position sensor. What else could cause this issue?

- Ignition Transformer Capacitor
- Wiring Harness
- Camshaft Position Sensor
Engine Ignition – No Fire
The electronic ignition (EI) system is a coil-on-plug ignition system. The coil-on-plug ignition system consists of the following components:
- Coil-on-plugs
- Spark plugs
- Crankshaft position (CKP) sensor
- Camshaft position (CMP) sensor
The coil-on-plugs:
- change low voltage signals from the powertrain control module (PCM) to high voltage pulses.
- supply the high voltage pulses to the spark plugs.
- are connected directly to each spark plug.
The spark plugs:
- change high voltage pulses into a spark which ignites the fuel and air mixture.
The CKP sensor:
- is a variable reluctance sensor.
- is triggered by a 36-minus-1 tooth trigger wheel mounted on the crankshaft.
- provides base timing and crankshaft speed (rpm) to the PCM.
The CMP sensor:
- is a variable reluctance sensor.
- provides camshaft rotational location information to the PCM.

My 2005 Ford escape hybrid is shutting off and saying stop safely now while I’m driving it. When it does this I have to pull over press the self jump start button by the brake sit for about 10 minutes and it makes a noise like something turns over and the car will restart and drive again. What could the issue be?
