    (2) Codes after Complete Rebuild

    I got the new engine assembled and installed. IT runs great but as soon as I plug the key in, I get a PO1502 and PO1511. with a long beep. Any help on this 1502 code?

    2004 GTX S/C and I already know what the codes are just trying to diagnose.

    History.

    Ski was perfectly fine 3 weeks ago. It spit the timing chain and bent some valves so I tore it down and completely rebuilt it with 2009/2010 valves, pistons and rings. Got everything buttoned up today, cranked it up, ran perfect again but throws these codes. Now, I did change out one of the 2A fuses for a 3A in the fuse panel on the day it spit the chain because I dropped the 2A in the hull so maybe the 3A fuse is the culprit for he PO1511

    From memory can't the tops plug be put on the wrong way around? Or connector swapped around? I can check mine when I get off work if your still having trouble.

    My connectors are in right. TOPS (Shut off) is 2 wire and OSPS is 1 wire. Same connectors though.

    I think my TOPS valve is done because the contact screws are rusted so bad that one of the contacts jus spins.

    Anybody got a TOPS valve they want to part with?

    the tops valve either clonks when you put the key on or does nothing if faulty. the sensor below the tops valve can be plugged wrong way around the retaining clip should be towards the motor not the gas tank.
    as for other code is the 3 pin plug at rear of the engine plugged in as this is the speedo sensor (this plug is often zip tied to intake pipe)
