PGM-FI Main Relay
The PGM-FI relay contains two separate relays. One is energized whenever the ignition is on which supplies battery voltage to the ECM/PCM, power to the fuel injectors, and power for the second relay. The second relay is energized to supply power to the fuel pump for two seconds when the ignition is switched ON (II), and when the engine is running.

PGM-FI ECU Main RelayBehind left side of dash, left of steering column. See Fig. 7 .

injectors are directly controlled by the PCM is MIL on ...is PCM showing fault code ??

Do you have power to the injector? Could be that the computer is not getting a parameter signal such as the camshaft sensor in order to pulse the injector/s-Or just the computer itself

Your getting 12V with ignition on from PCM. The ground comes from a junction connector near oil filter. If that seems ok it then leads back to the PGM FI main relay behind the dash
