engine won't start on 1997 Toyota Camry

i replaced the whole engine from junk yard (45T miles), i tried to crank but won't start continuously, but when i prime gas at intake port, it runs shortly, i checked the fuel gallery and the bleeder it has enough pressure, checked the fuel injector and crank it , no fuel steam comes out, meaning the injectors are not opening while cranking, please help me to trouble shoot this problem and I'll appreciate it so much, thanks

Sounds like the injectors are not getting the proper signal. Is there 12 volts to them on the power bus? ONLY use a DVOM to check for this, NOT a test light or you can fry your computer. Or, there is a defective electrical circuit or the engine does not REALLY match your computer system. Best of Luck!
