A Ford starter solenoid is one of the key components to the starting system of most older Ford vehicles. It's essentially a big relay, which provides power from the battery to the starter motor...

Typical problems caused by a faulty ignition module include inaccurate timing advance and retard, hot engine stalling and no starts. The Ford EEC 4 TFI module was located on the side of the...

Distibutor-less ignition systems have been around for a while now and, for the most part, have proven to be reliable. However, when they do malfunction, it can be difficult to troubleshoot them...

Automotive ignition systems are made up of several key components. The trigger device is the ignition module or points, and these supply energy to the coil. The ignition coil multiplies the energy...

The article explains how to replace the ignition lock cylinder. To replace the ignition lock cylinder, the trim panels around the steering wheel are removed. Then the tamper-proof hardware that...

Your vehicle's ignition coil uses 12-volt power coming in from a wire that gets electricity from the battery and alternator. The coil is also grounded using a similar wire, going either to the...

Sometimes it is better to clean your spark plugs than replace them. For myself, I have expensive racing spark plugs with platinum tips, so I'm not going to buy new ones every time they get dirty....

A steering column lock is an anti-theft device that prevents a vehicle from being driven after it's been started. While there are many models on the market, most column locks are installed in the...

A Mercedes-Benz does not use an external ignition control module. It has a distributorless ignition and uses one coil and two spark plugs per cylinder. While the C230 and the E320 use the same...

The purpose of the ignition control module is to distribute the signals from the electronic control module to operate the coils. The computer gets various signals necessary for proper engine...

Audi ignition control modules are the firing control for the coil packs. On a V-6 engine, there are three coil packs. The ignition control module is attached beneath them. It has a brown...

Ignition control modules were introduced along with fuel injection. Electronic fuel injection requires a computer coupled with a host of sensors for situational input from the engine to...

There are many things that can cause a car to stall while driving it. An engine is made up of many parts, and many of those parts are either governed by a computer or provide input to the computer...

The EGR is an exhaust gas recirculation device used for the purpose of lowering emissions. The purpose of the EGR is to allow a certain amount of exhaust to return and be mixed with the incoming...

Hot-wiring a car enables a car to be started by bypassing the car's ignition lock on the steering wheel column. Normally, a key has to be inserted into the ignition lock and the key turned in...

Changing the spark plugs on your Mercury is easier than you think. Like many newer cars born in the new millennium, they use a DIS or Distributorless Ignition System, with a COP or Coil On Plug...

Your ignition module is, very simply, an electronic switch. This switch times the firing of the spark plugs with the rotation of the pistons. Without this switch, the engine will either not run at...

Your ignition module is responsible for timing the firing of every spark plug. When the ignition begins cranking, the ignition module switches the ignition coil on and off. The module also...
