no..if its bad your car wont start
Yes. If the ignition is malfunctioning, the spark plug will not ignite. A bad ignition module, a bad spark plug or a bad plug wire are the most common causes of that (besides a bad battery, of course).
bad ignition coil, bad plugs. bad plug wires, bad ignition control module........
Things to check: Distributor cap, Plug wires, spark plugs, Ignition coil. On that year this is the most common things that would cause an engine missfire.
Ignition module.
check your plug wires, then your coil packs, then your ignition module.
The 1990 Chevy Celebrity engine is distributorless, the ignition is handled by a combination of the engine control module(computer) and the ignition control module. You did not mention which engine the car has. If your car has the 4 cylinder engine the ignition control module is below the intake manifold at the rear of the engine. You can follow the spark plug wires to it. The coils are mounted to the ignition control module. If your car has the V6 the ignition control module is near the starter and again you can follow the spark plug wires to it. Again the coils are mounted to the ignition control module.
No but, if you leave a plug wire disconnected and not grounded while running the engine, you can damage the ignition module.
Ignition misfires and "sputtering" can be caused by any number of system failures such as air/fuel, ignition and even emissions/exhaust. A failing ignition coil, control module, plug wire and plug are often components that should be examined when diagnosing such misfires.
Catalytic converter due to unburned fuel being burnt in the converter. It can also cause damage to the ignition module.
did you changed your thermostat? You MUST keep around 195 degree thermostat in the vehicle at ALL TIMES due to the computer system. The ignition module usually gets hot due to corroded electrical connections at the ignition module and or the module is HEAT SENSITIVE and needs to be replaced. (plug wires) Ignition misfire can produce a variety of driveability symptoms including hard starting, rough idle, hesitation....
There could be several things to cause no spark, but one I have ran into is the Ignition Control Module inside the distributor or the coil inside is bad. If your plug wires are good and your wiring to the distributor checks out, then it's either the coil or the ignition control module. Both are inside the distributor.
Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another.Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn ringsFaulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common.
