Fuel press on the 4500 shows 10 PSI with engine not running

Hi.

We've just finished wiring the 4500 and all seems to work fine except the fuel-pressure: it shows 10 PSI with the engine not running.
Anyone have an idea why?

Thanks

Do you have the ground wire on the screen case screw?

Have you selected the correct sensor part number in calibration?

Does the sensor have a good ground connection at the threads?

Is the shift adjust value 0?

Thanks for chiming in Rob.
The EFIS are out for the moment due to final wiring, but I'll check the items you mentioned once the 4500 is back in late next week, and I'll report back then.
