Samurai TBI | No Injector Pulse

[d8nk]

the pump must run for 3 seconds key on, if not find out why, fuel pump relay bad or FI fuse blown or IGcoil fuse blown.
just listen as you key on for the 3 second fuel prime sound.
im sure it is  ok, and  you checked PSI but just hearing that sound tells me the priming pulse happened, and any relays that chatter , ECU CAPS are bad. 
Im always looking for other odd things any ECU does in the logic, if injectors are dead, look for other oddities.
like, CEL dead. or
blinks out code 12 and repeats or as it repeats,  halts mid flashing code sequence, this is ECU crashing for bad CAPs. seen that many times. and relay chatter sounds.

The pump definitely runs with key on. CEL is good, no funny relay chatter or anything. The code 12 blinks 12, then pauses then repeats 12, pauses, repeats, etc. That is normal right?
