Thoughts;

Do you have access to live data with an onboard display or controller?

If so, check that all sensors are showing a normal value.

*Ambient air temp correct?
*Coolant temp correct?
*TPS correct?
*MAP correct? [connect a vacuum source to the MAP, it should show a voltage range with different vacuum levels applied]
*Fuel pressure correct?
*Are the injectors pulsing? [check with noid light tester or "listen" for the injector ticking with a listening device]
