88 3vze injectors wont fire

got a 88 4x4 pickup for super cheap, but was missing the top end due to burnt valve. so i bought a 88 4 runner with locked up bottom end and put it all back together. and then back apart because the injectors will not fire, can ground them out and they all fire and pulse fine, but other than that they do nuthing. changed the computer, relays, and some other stuff, but still no fire. thinking maybe a bad ground somewhere but not sure. had to guess at all the wires, and hoses because all were off both engines, but im pretty sure all that is close enough to work. any ideas?

apparently if the air flow sensor is bad the injectors dont open, changed that and it started up.
