A bad ignition module will cause a no start situation in a vehicle because the needed spark is not created. It is responsible for telling the distributor when to fire.
The engine computer is also the ignition module.
An ignition module problem could be the cause of your 89 Geo Spectrum not starting and not getting any fire. It could also be the pickup coil causing the problem.
The ignition module is located under the three ignition coils. The same bolts that hold the coils in place also retain the module to the mounting bracket. To find the coils, follow the ignition wires from the front of the engine to where they attach at the rear. The wires clip to the coils.
The ignition module could cut off the fuel supply. The oxygen censor will also cut off the power from an automobile as well.
It totally depends upon what is wrong with the ignition module. The ignition module's job is to know when the correct time is to send current to the ignition coil. This is what generates the "spark" in the plugs. If the module is not sending current to the coil, no spark, and thus no go. If the module is sending weak current to the coil, the spark will be weak, and that will lead to poor starting, underpowered performance, unburned gasoline getting to your exhaust, and other nastiness. If the ignition module is not firing at the correct time, then that is even worse; that can lead to pinging, knocking, incomplete combustion, lack of power, burned up pistons. Ignition modules also can become "heat" or "cold" sensitive, where they will run intermittently or not at all when they have warmed up, or when they are cool. So, the short answer is "maybe, but it isn't good."
The only way I can explain it is to follow the wiring from your coil pack (where the spark plugs are) and the wires plug into the ignition module. Also go go www.wrenchead.ca and it has a manual that explains all. if you don't know the answer to a question please keep your moth shut ,please don't waste my time
under the distributor cap. it is black plastic and has 2 small screws in it New answer: Sorry but that year did not use an ignition module. It use a crank senser and cam senser. If this is a S10 with the 4.3 L engine, it has an ignition module and it is attached to the bracket that also holds the ignition coil on the passenger side of the engine.
It is on the left side of the engine. You will see a coil and that is the module also. It is one unit.
The Term "Ignition module" can be applied to more than one item. On older cars with a Distributor and coil pack, the ignition module is an electrical switch that turns the power on and off to the coil, which in tern causes the coil to generate a spark. On more modern cars that do not have a distributor, but have fully computerised ignition systems, it usually refers to the ignition coil, which also incorporates the item mentioned above. In both cases it's responsible for causing a surge of high voltage electricity to be supplied to the spark plugs to cause the petrol/air mixture in the cylinders to ignite.
yes the 2.5L 4 cyl engine has the ignition module mounted to the back of the engine block,firewall side.the crank sensor is also there under the moduel and coils
5.5mm bolts are the kind of bolts that hold the ignition control module in a 1987 Ranger 2.3L. However, 5.0mm bolts may also work.
if you're getting fuel to the throttle body it could be the ignition module if your getting fuel this is more than likely the problem, it could be coil pack if not getting any spark from any of your plug wires if your not getting fuel or spark at the same time i believe it may be your control module if control module is out u wont get fuel or fire my 89 is getting fuel but no sspark and i was told it was my ignition module auto zone knew exactly what my problem was try calling them they can also test your ignition module before u spend money on one if its not the ignition module
