Hello,
we have a p6000 displaying E-35 for low voltage at fuel injector. injector is only getting 2.3V, it's pulsing but, the lift wont run for more than a few seconds to a couple minutes. I'm not familiar with these CAT lifts and don't have any schematic or service manual available. this all started after our shop hand pressure washed the engine.

Any help would be great.

Edit: i just checked power at the injector driver with engine running and only had 2.3v being supplied. would the injector driver be bad or could it possibly be a relay? I already moved relays around without any change or additional fault codes popping up.
