Strange setup problems

[Richard L]

There is not reason why the system will not inject. Your reasoning for the injector at 0.12V is correct, so the H3 system thinks the injector is at 100% DC.

Most cars powers up the fuel injector at "pre-crank" position. Yours doesn't. Until of course after the engine has started.

Can you check all the jumper links are at the "default position" and the gauge is switched on.

There test pins

I will put the injector+ wire back to pin 60 so that it will be powered at the pre-crank position. Then I will add a 10000uF capacitor in series with the injector- to block the DC.

Jumpers are at the "default position" and the gauge is switched on.
