the engine won't run if it is completely bad. you won't have spark. if it is just starting to go bad it might run good for days or weeks but can cut out at any time and the engine will die. it might restart right away or you might get it to start after some time. if you are getting intermittant ignition problems it is a good idea to get it replaced. carry a spare with you too so you won't be stranded in the future.
Maybe the igniton control module or the ignition module are making bad contact.
bad ignition coil, bad plugs. bad plug wires, bad ignition control module........
It could either be a bad ignition coil, a bad ignition rotor, a bad ignition cap, a bad ignition control module (if equipped), or a bad coil to cap wire.
== answer== Could be a bad ignition control module or coil,points if equiped,cap,or rotor,bad ignition switch.
your control module did go out.
Crank sensor has failed,Ignition control module (ICM) has failed,Bad ignition coil pack,
depends on early or late model. lots of early models will just shut off while driving down the road etc, and never start again. cant rmember right now on late ,mind is on another project, sorry
dead battery, or a bad ignition control module inside the distribureator.
Probably a bad ignition control module..Autozone for $105-$160..
Many autopart stores have a machine to test it. The machines use a universal adapter to hook into the ignition control module. The ignition control module is in the distributor. If you mean the part that contains the ignition coil, when mine went bad I probed it with an ohmeter and then asked the parts store if I could test the resistances in a new coil before I bought it. Since the resistances of certain terminals weren't even close, I knew I had a bad coil.
Yes, My ignition module was bad, I experienced intermittent stalling. My mechanic replaced and it stopped.
have your ignition control module tested.(heat test) sometimes when the ignition control module goes bad , no starting/hard starting when vehicle is hot is a common symptom.follow up questionwhich is more likely the ignition control module or crank shaft rotation sensor and why?
