Need a 5-OH whisperer

Another option is to disconnect the O2 harness completely (to avoid firing the ECM), install the A9P computer for troubleshooting. This will help you determine if it is the ECM. One last step before starting with a bump starter (attached to the stater solenoid, not the ignition switch) check your TPS/Key on with the new ECM. Should be in the 90s. If it is let her rip!
