How do you troubleshoot an electronic ignition?

Here's How To Diagnose Your Ignition Issues

Verify Lack of Spark.
Check for Any Obvious Issues. ...
Probe for Power. ...
Double-Check Firing Order. ...
Double-Check Initial Timing. ...
Test/Inspect Spark Plugs. ...
Test Spark Plug Wires. ...
Check for Spark at Coil.

How do you check for spark on electronic ignition?

Systems connect the testers indicator end to the spark plug wire boot and the other end to the spark

How do you check an ignition coil with a multimeter?

That's one before you start the car and then you get grab your multimeter. Put it on DC voltage.

How many ohms should a ignition module have?

A typical value would read 0.4 - 2 ohms.

What causes electronic ignition failure?

Faulty Ignition Coil They can wear out, break, become fouled, or carbonise if left unchecked for too long. This causes the electric charge held by the coils to fail to reach the spark plugs, resulting in misfires and failures as the coil degrades.

Does electronic ignition need a resistor?

Electronic ignition systems, whether factory Mopar or aftermarket, don't utilize breaker points, thereby not actually needing a ballast resistor to control amperage through the pickup coil.

Does electronic ignition have pilot light?

Electronic ignition is a device that replaces conventional pilot lights in almost all newly manufactured furnaces. There are two types of electronic ignitions: a hot surface ignition and an intermittent pilot.

Is there a condenser in electronic ignition?

Electronic ignition does away with the need for a traditional condenser and points, so these need to be removed by unscrewing them from the distributor base-plate.

What if my ignition coil has power but no spark?

There are a few reasons for no spark, new coil pack could be defective, crank sensor, ignition module or bad wire in primary circuit, faulty ECM/PCM. You may have to have a good technician have a look, diagnose and estimate repair.

What sensor would cause no spark?

A Bad Crankshaft Position Sensor The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn't know when to fire the fuel injectors and ignite the spark plugs.

How many volts does it take to see a spark?

So right about 3000 volts is the minimum needed to spark.

How many ohms should a 12 volt coil have?

You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, a little less is ok but no more.

How many volts should an ignition coil read?

To check that voltage is reaching the coil, connect the voltmeter between the + or SW terminal of the coil and earth, and switch on the ignition. The meter should read nearly 12 volts, or about 7 volts if the coil has a ballast resistor.

What should the voltage be at the coil?

The reading here should be 11.00 or better, with 13.49 being about normal. If your coil reads under 11.00, then chances are pretty good that this is the reason you're not getting any spark or a very weak one.

What are the signs of a faulty ignition module?

engine is misfiring or running rough: an engine misfire results from incomplete combustion. a faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs rough. the engine may also run well at low speed, but won't accelerate well.

How many ohms Should a coil wire be?

The coil wire should have 1200 to 2800 ohms resistance.

How many volts do ignition coils produce?

Modern coil designs produce voltage pulses up in the neighborhood of 40,000 volts from the interruption of the 12 volt power supplied by the battery. Some modern engines have multiple ignition coils mounted directly on the sparkplugs.

How long does electronic ignition last?

Depending on manufacturer the service intervals can range from every 5,000 to 15,000 miles. For a classic car that gets driven 1,000 miles a year, that is a trouble-free system. The basic workings are familiar to any car buff. An ignition coil contains a pair of windings around a ferrous core.

What is the most common ignition problem?

1. Faulty Ignition Coil, Spark Plug, or Spark Plug Wires. An ignition issue can be caused by a faulty or failing ignition coil, spark plug, or spark plug wire set. These critical components of your ignition system keep your engine running smoothly.
