88 S10 INJECTOR PULSE

1988 All Other Makes

1988 s10 with 2.8 V6, TBI, died at store, would start when spray gas into carb, then die.
Have replaced fuel pump, ECM, wires, cap, rotor, and fuel injectors.
The injectors all read 1.5 ohms on volt meter, have replaced with used set of known good injectors anyway, and checked fuel pressure.
The injectors pulsed a couple times then stopped.

Still the injectors will not pulse. I checked the original injectors by tapping with wires hooked directly to battery (not hooked into wiring harness!) And they would pulse then.

Even replaced all fuses.
What else could keep the injectors from pulsing?
Could the ECM be bad again?
No trouble codes either.
I hope someone can help me with this I am at wits end.
