    S54 Swap Starts then dies

    I have been putting together my first e30 s54 swap and have had trouble trying to get it to run. It starts for a second and then dies. My setup includes:

    Walbro Fuel Pump (High pressure, 5.5 bar)
    Stock s54 FPR
    Modified my DME with ECUWORX tool(EWS removal). Is there anything else I need to do to it??

    The Error Codes I get are:
    139 Interruption, cruise-control operation
    44 2C YES Signal, thermal oil level sensor
    81 51 P1568 Interface, multifunction steering wheel
    132 84 P1613 CAN timeout DSC
    133 85 P0600 CAN timeout, steering angle sensor
    134 86 P1612 CAN timeout, instrument cluster
    79 4F P1490 Signal, temperature sensor, exhaust gas
    106 6A Signal, brake light switch
    66 42 EWS interface: no communication
    43 2B Signal, temperature sensor, radiator outlet

    All these error codes make sense, since I have eliminate all this stuff. Any help would be greatly appreciated. I've checked most of the sensors in INPA and they all seem to be reading. I've tried to delete adaptations. I've tried with the maf plugged in and not plugged in.

    Any help would be greatly appreciated.

    Is the fuel pump running past the initial prime? Check fuel pressure.

      The fuel pump is definitely still on when the car stalls out. I put a check light on the fuel pump and it stays on after the engine stalls.

        I'm not 100% sure that it will run with just the EWS delete. I never tried mine like that, I went straight to the E36 chassis config. R3Z3N has a lot of good info on the DME changes in his build thread. If you can't figure it out let me know and I can get you the changes that I made to get mine running.
