What is the ignition system in a 1987 Toyota?
The 1987 Toyota ignition system consists of the distributor — which houses the coil and crank sensor — ignition igniter and the engine computer. The crank sensor sends a signal relating the position of the crankshaft relative to top dead center on compression stroke to the engine computer.
What happens when the ignition fails in a Toyota?
When the ignition system fails in a Toyota, generally it’s because the igniter transistor has gone south. To confirm your diagnosis, the crank sensor and the coil should be checked in the process of elimination.
Why does my car have no spark when I start it?
As a result, This occurs after the ignition coil or module gets too hot. Furthermore, it could correct itself after the engine module cools. In some cases, a bad ignition coil will result in the vehicle not starting it all. A Bad Rotor Or Distributor Cap (cracks or carbon tracks that are allowing the spark to short to ground).
Where is the ignition igniter on a Toyota?
This activates a transistor in the igniter, which fires the coil. The igniter then sends a return signal to the computer of confirmation of firing. The computer uses this to regulate the firing of the fuel injectors. Locate the igniter. It is a 2-inch square box located either on the driver’s side fender well or on the side of the distributor.
Where is the ignition module located?
On some cars, the ignition module may be housed on or inside the distributor. In other cases, it may be a standalone unit, or it may be integrated into the ignition coil assembly. The ignition module is easy to access and replace on some vehicles, but on others, it’s buried deep inside the engine compartment.
How does the ECM control the ignition timing?
On some vehicles, the ECM may control ignition timing above a certain engine RPM, while the ignition module has control below a certain RPM. In these instances, the signal from the sensor may first be sent to the ignition module.
