Fuel pressure should be up to spec
check TPS volts
check injector for power
ECM ground the injectors
if power and ground wires all OK
no codes fuel pressure ok
TPS volts OK
suspect ECM

Check for power at the injector harness connector power there and no pulses could mean the computer ground drivers
