Anytime you make a change in the Holley you should do a TPS autoset for the Holley to activate the injectors and coils to fire.

8. Plug in the USB cable to the ECU and Laptop. At this time, communication status should change from “Offline” to “USB Link”.
Next, turn the vehicle’s ignition power to “run” (not start). Click the “USB Link” once. A screen should appear that will compare the
files in the ECU with the file in your laptop. They will not be the same. You want to select the “Send To ECU” button at the bottom
of this screen. This will send the new file you created to the ECU.
9. Once this is done, leave the ignition powered. At the top of the screen, select the arrow on the “Sync” button. Select the “Perform
TPS Autoset” function. It will guide you through steps to set the TPS. Slowly depress the throttle from closed to fully open twice.

SYNC button
NOTE: IF YOU DO NOT PERFORM A TPS AUTOSET, THE ECU WILL NOT FIRE THE INJECTORS OR THE IGNITION AND THE
CAR WILL NOT START! IF THE TPS IS NOT SET, YOU WILL SEE A WARNING AT THE TOP OF THE SYNC SCREEN
AND THE TPS WILL SAY “NEEDCAL” ON THE MONITOR SCREEN.
NOTE: ANY time you adjust the throttle linkage (in the future), you must perform a “TPS Autoset” after adjusting the linkage.
10. Shut the ignition off. Turn the ignition back on (do not start). You should hear the fuel pump start and stop after about 5 seconds.
If you do not, diagnose problem.

Dang. That is good info if it is what is causing his issue and it makes appreciate my FAST XFI even more.
