    MM3 Tuner - Stopped Receiving Rail Pressure Data

    I just had a local shop change my water pump, hoses, thermostat, etc.

    I removed the MM3 from the truck for safe keeping.

    Prior to taking the truck in my MM3 read my fuel rail pressures.

    I drove the truck for about 50 miles after picking it up from the shop, no problems noted.

    However, now that I have hooked the MM3 back up the fuel rail pressure readout is showing NA (I assume Not Available).

    I do not have a clue where to start looking with this problem.

    No CEL and the truck is running fine.

    This morning I will unplug the MM3 from the OBD port, and all connections and then plug them back in?

    I have been searching but have not found any viable info regarding this problem.

    Any info or guidance would be appreciated!

    Thanks!

    I just wanted to update my post. I unplugged the MM3 (every connection) and then reconnected everything (including my new EGT probe).

    To my pleasant surprise, everything came up including rail pressure and the new EGT.

    I pray nothing else goes wonky...but if it does, unplugging and reconnecting everything will be my first order of business.

    Will be pulling the little camper back home shortly (had to move it because of the hurricane situation).

    I'm looking forward to seeing what the EGT and tranny temps will be.

    Still learning all this diesel stuff.

    Thanks!
