Of course their will not be if both plugs are out of the cylinder and there is not compression.

Ignition Coil Primary Circuit Test
Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is 0.5-0.7 ohms. If primary resistance is not within this range check out test results below.

Ignition Coil Secondary Circuit Test
With the ignition coil removed from the motorcycle and the ohmmeter set to the RX1K scale place the ohmmeter leads on the secondary coil windings B (middle terminal) to
R (rear secondary terminal/socket), B to F (front secondary terminal/socket) and check for secondary coil winding resistance which normal resistance range will be 5.5-7.5K ohms. If secondary resistance is not within this range check out test results below.

Test Results
A low resistance value indicates a short in the coil winding which requires coil replacement.

A high resistance value might indicate that there is some corrosion/oxidation of the coil terminals requiring the coil terminals to be cleaned and the resistance test then repeated and if after the test is repeated the resistance is still high after the terminals were cleaned the coil must be replaced.
If there is an infinite ohms or no continuity) resistance value the coil is open and must be replaced.

If you have spark, it sounds like either the sensor in the timing cavity of the engine is bad or the electronicignitionunit is bad.

No spark to engine 1991 ford pickup


It can be faulty or dirty spark plug itselfd.Also for reference get the fuel level checked.Is the fuel tank is empty or near to empty.
Try cleaning the spark plugs and then see if that is helpin.On some cases the black carbon layer gets collected on the spark plugs and that causes the problem,so cleaning the plugs help.But if its not helping,then spark plug has to be replaced.Spark plugs get power from ignition coil to ignite sparks.If ignitioncoils are faulty then also there will no spark.--------------

Firing Order diagram for 2006 Ford Explorer


Hope this helps. The ignition coil:
  • changes low-voltage pulses from the PCM to high-voltage pulses.
  • fires 2 spark plugs simultaneously.
  • has 3 transformers.
    • One transformer fires the spark plugs for cylinders 1 and 5
    • One transformer fires the spark plugs for cylinders 2 and 6
    • One transformer fires the spark plugs for cylinders 3 and 4
Spark plug wires:
  • carry high-voltage pulses from the ignition coil to the spark plugs.
The spark plugs:
  • change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.
The firing order is 1-4-2-5-3-6.
