Are you sure you got a good ground on terminal 37 of the ECU? If not the FI light just stays lit. Testing a relay is easy; all you need a voltmeter and a 12 volt power source.  Energize the relay and the meter should read, disconnect power source and it shuts off.

Pulled over to side of the road to throw on a shirt. When I turned on ignition switch, did not hear the  DFI system power up, then seen the FI led light stay on. Took off the side cover to check the DFI main relay. It made a buzz sound (not normal I think) when ignition switch was turned on. Removed the Main Relay, taped it lightly, then reinstalled, the buzz noise was gone, and was just making a clicking sound when ignition switch is turned to on position (normal I think).
By doing the above, I got the engine to turn, but still did not hear that DFI system power up sound when u turn on ignition key.

When I tried to get a fault code, the FI led just stayed on?

Silly Question- Can a simple relay be bad considering the above, and cause the above?

Why am I not getting a fault code?

Input will be appreciated.
