When the ignition module fails, the engine turns over normally, but doesn't even sputter or kick like it's trying to start. Of course, other situations like a failed fuel pump or even a clogged fuel filter can cause the same symptoms. Therefore we're going to grab an inexpensive inline ignition spark tester to verify we don't have any spark at all reaching the spark plugs.


Electrical Systems/Wiring - bad ignition module symptoms? - do ignition modules act up and have symptoms when there starting to go bad?or do they just die and thats it?


Symptoms of a bad ignition module are sudden engine stalling or power loss while the car is in motion, engine stuttering accompanied by a smell of gasoline and an inability to restart the engine following a stall. Decreased gas mileage is also a sign of a compromised ignition module. Ignition module failure can be caused when the unit overheats.


Anyway, I am thinking it is a bad ignition module (ford is known for those), and it HAS been getting worse since its been getting hotter (it was around 110 today). However, I have had no problems starting the car (yet). Do you think my assumption is correct? Thanks.


Whether your Ford or Mercury car or truck CRANKS but DOES NOT START or runs with a MISFIRE Condition, this article is for you. With the tests I'm gonna' show you, you'll be able to pinpoint the problem to the ignition control module or the ignition coil or the Profile Ignition Pickup sensor (PIP sensor) or the spark plug wires or the distributor cap.


Ford used the TFI ignition module (thick film ignition) on vehicles from 1983 through the mid-1990s only. The vehicles that used this module had a conventional hall-effect distributor with a separate coil. The TFI module was located on a flat area on the base of the distributor.


Ignition module failure is no joke because it often leaves you stranded. The complaint is the engine cranks normally, but does not start. The cause of an ignition control module failure is often associated with age and damage from heat buildup.

ELECTRONIC IGNITION In 1974, Ford began using an electronic ignition system known as Duraspark. The Duraspark ignition system consists of a Motorcraft distributor with a magnetic pick-up and an ignition amplifier that mounts on the inner fender or firewall. The Duraspark ignition system is simple to install and use.


A vehicle's ignition module controls the timing and functioning of spark plugs. The vehicle's performance is affected if the sparks plugs misfire or stop producing a spark. There are several signs that indicate an ignition module is bad.
