2005 Ford EscapeGetting 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?


  • PCM Fuse
  • PCM
  • 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.

  1. 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?
