Is fitechefi intake leaks
Update ! Have engine running ok IAC 3 to 5 rpm 850 tracking set idle ok. AR set at 14.5 stays close w/ small adju segments. Had to turn off pass 02 becouse of exhaust leak. Still can't find the problem why there's no fuel pump turn on signal. Fitech has3 no clue why and can't find a led to the problem on any site yet ! To start and run engine I have to ground yellow relay pump wire. I guess I'll have to run an additional relay system !

Have you tried reloading the Software to ECU?
Save your tune to the handheld. Then go to ECU programmer menu and initiate programming from handheld to Ecu. After complete, turn key off, let ecu power down. To key on and load your tune back in. Once done, turn key off, let ecu power down.
Sometimes the ecu gets a little confused and needs fresh software.
Went to shop tonight and made 2 cycled loads. fuel pump still won't turn on.
Check you pins on the harness. May have one bent or pushed out.
