Duraspark II electronic ignition was used on 1977 to 1984 Ford V-8 passenger car and light truck engines. This article refers to the Duraspark II control module with a BLUE strain relief bushing, one 4-pin connector, and one 2-pin connector.

When did Ford stop using Duraspark?

DuraSpark II, on the other hand, remained in use though until 1986. Ford did make several varieties of modules, some for special applications like high altitude, but most used the common and reliable “blue strain” module.

How do I know if my ignition module is bad?

Signs of a Bad Ignition Module

  1. Acceleration Issues. The vehicle may shake, vibrate or jerk when the gas pedal is pressed. There may be hesitation or lack of power during increases in speed.
  2. Temperature Problems. A faulty ignition module can cause a vehicle to overheat.
  3. No Power. The engine may turn over without starting.

Does Duraspark need ballast resistor?

Taylor Ford Duraspark canister coils have special windings and high voltage output. They do not require ballast resistors and they feature the same style connectors used on Ford Duraspark ignitions.

How do you diagnose a bad pickup coil?

Signs of a Bad Pickup Coil

  1. No Engine Spark. The pickup coil sends the signal from the ignition module to the spark plugs during the ignition process.
  2. Rough Idle. Because the spark plugs are not communicating proper timing to the fuel injectors, a rough idle may occur.
  3. Engine Stall/Failure to Accelerate.

How do you test Duraspark?

Measure the cranking voltage to the ignition module, or “brain-box”. Probe the white wire leading into the module while cranking the engine. Inspect the circuit from the starter solenoid “S” terminal, if the voltage is weak or missing entirely. Replace the solenoid if no faults are found in the circuit.

What year did GM go to electronic ignition?

Electronic ignition was first used on Chrysler production vehicles in 1972 with GM and Ford following in some large V-8 applications in 1974.

What happens when a pickup coil goes bad?

A pickup coil that has failed, or is about to, may also cause engine stalling and an inability to accelerate smoothly because the fuel injectors are not firing properly. Once stalled, the vehicle will not be able to start again until the engine has completely cooled.

What makes pickup coils go bad?

Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.
