Buick LeSabre: Customer Replaced ECM / No Start : The Final Diagnosis

Buick LeSabre: Customer Replaced ECM / No Start : The Final Diagnosis

In the first video “Buick LeSabre: Customer Replaced ECM Now A No Start, No Lights, NO NOTHIN!” https://www.youtube.com/watch?v=NAUkmDhjgEM&t we had a look at this Lesabre that was towed in after the customer replaced his own ECM causing a no start. After we got the vehicle up and running it was obvious that it needed some work to fix the original complaint. We had our suspicions about a plugged exhaust, so let’s see if our hunch was correct! -Enjoy!
