    Hi all!

    I'm really hoping someone has some ideas here, because I am stumped!
    2010 tacoma TRD off-road 4.0, started stalling when accelerating, idled fine, and if you were really easy on the gas pedal it would run fine. Threw 2 codes p0171 and p0174 (too lean bank 1 and 2) My first thought was MAF, cleaned it, no go... Replaced it, no go. Being it is about 11 degrees here I drove it down to my buddy's shop to check the fuel pressure, and that's where she died, won't start at all. Checked the fuel pressure, there was none (checked while cranking) Fuel pump relay is good, COR is good, fuel pump went bad, right??? No.... not it. Discovered there was no power going to the fuel pump, so we tested the the crank shaft sensor, that's not it either...For the life of me, and two other mechanics, we can not figure out what the issue is.

    Any thoughts, ideas, or experience with this issue would be greatly appreciated.

    If the Circuit Opening Relay is working like it should.

    Open Circuit between the COR and the Pump
