Hey I purchased a new ECM from Flagship 1 for my Regal and my car won't start after installing. I've tried performing the Pass-key 2 relearn and it did not work.

Is there any way to relearn the system or is there a way to disable the security system for my car to start with the new ECM?

What procedure did you use.

Passkey 2 Relearn following these steps:

1. Insert ignition key and turn to the “ON ” position. Do not attempt to start the engine. Leave the key in the “ON ” position for approximately 11 minutes. The security light will be steady on or flashing for the 11-minute period. Do not proceed to Step 2 until the security light turns off or stops flashing. 2. Turn the ignition switch to the “OFF ” position for 30 seconds. 3. Turn the ignition switch to the “ON ” position as in Step 1 for 11 minutes. 4. Turn the ignition switch to the “OFF ” position for 30 seconds. 5. Turn the ignition switch to the “ON ” position as in Step 1 for 11 minutes for a third time. 6. Turn the ignition switch to the “OFF ” position for 30 seconds for a third time. 7. Turn the ignition switch to the “ON ” position for 30 seconds. 8. Turn the ignition switch to the “OFF ” position. 9. Attempt to start the engine. If the engine starts and runs the relearn is complete.

Side note: I see you're from Flint. I use to live off Ballenger!

Would this work to start the car with the new ECM?

Did you do the learn cycle three times? You MUST allow it to turn off the light off and do it three times.

I followed the instructions exactly 3 times with no success. The car'* security light (if it has one) did not appear during the process.

As far as I am concerned you can't relearn keys when swapping the ECU on 94 and 95 models. I read that you have to remove the old ECU'* EPROM chip and put it into the new reman. ECU.
