No initial start after install

• If the vehicle does not start, refer to the "Pre Tuning" section of the Tuning Manual for initial start procedure. If, after you have followed the procedure with no success and the plugs are not wet, try priming the engine. If the engine fires and runs after priming, go to the next section "No Start".

• Go to the "Final Wiring" section in the Tuning Manual and perform the final wiring test.

• Verify that the white wire from the ignition box is not attached to the white wire from the tach adapter. For correct installation, attach the white wire from the tach adapter directly to the "tach output" plug of the ignition box.

• Verify that the TPS is connected and adjusted. Refer to the "Pre Tuning" section of the Tuning Manual for throttle position sensor calibration instructions.
