How do you test the Electronic Control Module on a 1993 Pontiac Transport?
The only definitive test for the ECM for all possible problems is to establish a set of circumstances during which the behavior/symptom you expect is caused by the ECM always occurs and create these same conditions using a known good ECM.Failing that, you can test the vehicle systems around the ECM and determine that there is definitely no (external) problem other than the ECM to prove that the ECM is faulty. Typically, you determine which inputs and outputs are related to the undesired behavior and check for correct signals in/out of the ECM by backprobing the connectors and using suitable equipment including a quality multimeter and an oscilloscope. Do not forget to verify that the connectors make good contact at the ECM.Also, try gently tapping the ECM with a screwdriver handle or twisting the ECM with your hands.

What is ECM mileage mean?
The -E-ngine -C-ontrol -M-odule, or ECM recorded the vehicle mileage along with the odometer. The EMC mileage can be read by a scan tool at most dealerships or repair shops with the proper equipment. It is possible for the two mileages to differ slightly, but a large variance may indicate a faulty odometer, or possibly odometer tampering.
Why would the computer on a 87 firebird not flash codes?
It won't flash any if there aren't any to flash. It should at least flash code 12 when you use the test terminals. If it doesn't then you probably have a bad ECM. Make sure that you have power going to the ECM first. Most of the GM cars have a power wire running from the battery directly to the ECM. Make sure this is connected and the ECM fuse is good.
