How do I get the ECM to recognize the replaced Ignition Switch?

You replace the ignition cylinder and then turn the ignition (with key) to on position. All dash lights will light up in the on position. After a few seconds only the security light will flash. Leave the ignition on for 10 minutes while the security light flashes. At the end of the 10 minutes the security light will go out. This will be the first cycle of reseting the E.C.M. to read the new cylinder and ignition system replacement. At this point you do this process two more times. This will take proximately 30 minutes. At the end of all three cycles the car should come on. If you want someone to walk you through it E mail me at archuleta67@gmail.com.

91 dodge shadow 2.5 will not start when key turned ignition switch ignition switch bulb or the key part any ideas?
BETTER HAVE THE ECM CHECKED.ITS A COMMON PROBLEM ON THESE CARS.ITS LOCATED NEXT TO THE BATTERY ON THE LEFT FRONT FENDER.MINE DID THE SAME THING.THE IGNITION MUDULE IS BUILT INTO THE ECM.
1990 Jaguar XJ6 has no spark any suggestions and replaced ingnition modue and coil about a year ago. Could the ignition module purchased bought be defective Is there a way to test the ignition module?
I had the same problem with a 93 Jag. I replaced the ignition module, coil, crank sensor, and even the ECU computer and I still did not have any spark. I was stumped and studying the wiring diagram I replaced the ECM Main Relay that was the problem, it fired right up. The ECM Main Relay on the 93 is located in the passenger side of the engine compartment on the firewall and it is the farthest outboard relay. Simple fix. I sure hope this helps someone out there
Why would there be a pause after you turn the ignition before the car starts?
Just because the starter has been replaced, it still shouldn't be ruled out. I have had several occasions that a remanufactured starter failed. Typically Autozone or Advance auto parts stores carry these POS. Having said that, I would be looking for a bad connection or maybe an ignition switch. Some vehicles have a large heavy relay to drive the starter motor, if this is old, dirty or damaged it may be sluggish to operate Some new vehicles have a ignition switch that sends a signal to the ECM and the ecm tells a relay when to turn over the engine. These have a delayed effect. Brake pedals will be incorporated this way also, eliminated the hydrolic brake systems completely.
When you turn the key engine turns over but wont start?
Without knowing the make and year it's impossible to speculate. Could be a low battery not spinning it over fast enough, a bad ECM, a broken distributor, a failed ignition coil or any number of other things -.
What are parts of an ignition system?
Ingnition switch, relays/fuses, wires. Depending on year ecm(engine control module) 1-12 coil packs, or distributor and spark plug wires and spark plugs. Can have knock sensors, which adjust timing to compensate of fuel/atmospheric conditions.
I have a 1997 Ford Aspire that I replaced the ignition switch. I now dont have any fire to the ignition. Is there a problem with the ignition module or the ECM?
are all the connection plug in on the switch and did you have fire before replaceing switch
Is an ECM and ignition switch the same part difference on a jeep wrangler 1990 2.5?
No! The ECM is the Electronic Control Module (Computer), sometimes called ECU, Electronic Control Unit. The ignition switch is just that, the switch that controls the engine ignition, the power to the starter, starting and shutting the engine off, and power to the accessories.

How can you get information on the ignition system with wiring pinouts for power feed to the ECM from the ignition switch?
You can get wiring diagrams from MOTORLIT.COM or shop ,manuals from AUTOBOOKSONLINE.COM
What are the causes for no spark on a 1999 Ford Ranger?
No spark can be as simple as a ecm fuse blown, a bad ignition switch, defective ignition module or a bad coil.
What could cause a 1994 Chevy beretta not to start?
bad fuel pump, bad ignition, ecm wires removed, clutch safety switch, about a million things -berettaspeed15 bad fuel pump, bad ignition, ecm wires removed, clutch safety switch, about a million things -berettaspeed15
1995 jeep wrangler you are getting no spark from the coil you have replaced the coil replaced the crank sensor i took out the ecm and swapped it with one from a 1991 the 1991 ran with my ecm mine stil?
did you try the control module or the switch just behind the dash on top of the steering column
Your 93 festiva startsruns about three seconds then dies It will start right up again but dies again you have replaced distributor ecm and the ignition control module plenty of fuel too?
I know this seems obvious but you didn' mention checking the ignition switch. Possibly the start contacts are ok but the run contacts are open. This will result in the symptoms you mention.
Where is ecm located on 1983 Chevy c-10 could this be what is wrong no fire tried everything else?
No spark? Have you replaced the ignition module inside the distributor? That would be my guess.

Will the pick up coil in a distributor keep you from hearing the fuel pump run a couple of seconds when you turn the ignition on in a 1993 Taurus 3.0 you replaced the ECM and the ignition coil?
No. The fuel pump should run for 2 seconds when the key is cycled from off to run, regardless of whether there is a problem in the ignition system or not.
Ecm fuse have no power when the switch is on?
yeah your right
