93 Sonoma 2wd, 4.3 vortex, has spark and 61 psi fuel pressure at the fuel rail, fuses all good, no codes on the obd-1, suspect injectors not firing. What fires injectors, I see ecu reads tp sensor, crank and cam sensor first. Do I have a bad ecu?

Parked it, and it would not restart. Not even a cough. Just the starter turning the motor.

Squirt some gas in intake to see if it runs just to be sure.
