Basic trouble shooting should start with checking for spark, checking for fuel, reading the plugs, etc. If you are relatively certain it is fuel injection related see the troubleshooting flow chart on the Affordable Fuel Injection CD or the web site https://affordable-fuel-injection.com/wp-content/uploads/2019/09/TBI-INSTALLATION-INSTRUCTIONS_v10.pdf#page=11 . If that fails contact rick@pattonmachine.com. If you are contacting Patton Machine for assistance include pictures of the installation, fuel pressure, error codes, timing setting, Datalog and BLM files.
