When did the Mazda RX-7 ignition system start?
This month’s Diagnostic Dilemmas will try to explain the Mazda RX-7’s ignition system operation, and how the ignition systems (yes, systems – these vehicles have two) can be evaluated in an efficient manner. We’ll focus on late 1980s and early 1990s RX-7s. Rotary Engine Principles [go to top]
Can a bad ignition switch cause a car not to start?
However, if your car has ignition switch problems, you may not be able to start the car at all. Ignition switch problems can also cause issues on the road, such as unexpected shutdowns or electrical problems.
Where are the spark plugs on a Mazda RX-7?
The crank turns at a 3:1 ratio to the rotor. The purpose of the trailing spark plug is to continue the burn for more complete combustion and reduced emissions. The leading plug is the lower plug in each housing, and the trailing plug is the top plug in each housing. Fortunately, each plug hole is marked with an “L” or a “T.”
Where are the pick up coils located on a Mazda RX-7?
Figure 5 is a much simplified schematic. The G and Ne pick-up coils are located inside of the crank angle sensor. Their output is sent directly to the PCM. IgT is the ignition timing signal (trigger) sent to the igniters from the PCM.
Can a bad ignition switch cause a bad starter?
The first thing to check in these situations is the battery. If the battery is OK, then you have either a bad starter or a bad ignition switch. With a little bit of time and some patience, you can tell which one is the problem. What Else Is Working?
Where is the starter on a car that won’t start?
To figure out why your car won’t start, it helps to know the difference between the starter and the ignition switch. The starter is an electric motor that cranks the engine, effectively starting the car. It is under the hood, usually on the passenger side at the bottom of the motor next to the transmission.
What’s the best way to fix an ignition switch?
How To Fix It: The best way to do this is to get a new lockset, with new keys and a new cylinder. You might consider getting a matched lockset that includes the door and trunk cylinders. The ignition switch itself is connected to the ignition cylinder by a shaft or lever.
What happens when the ignition switch is off?
Generally speaking, in the “OFF” position, the ignition switch doesn’t connect anything; in the “ACC” position, the radio or fan may be energized; in the “RUN” position, the engine control module is energized; and finally, in the “START” position, the starter relay is engaged. (These generalizations, depend significantly on year, make, and model.)
