    I just completed my engine swap, I just installed a new m20b25 rebuilt motor.

    the motor is cranking, All sensors are in, But the alarm that hasnt worked in years seems to be going off. all of the lights are flashing. I need to disengage it. Help!

    Ripping the alarm out would be a good start...

      well my friends dad came over, he owns a alarm installation/ audio place. He says its not my alarm thats causing the motor to not run. I checked my motor and I am getting spark. I am also getting fuel up to the fuel pressure regulator. The motor is turning over but its just not startin up.

        Are the injectors spraying? What about your Cold Start Valve?

          make sure all those sensors are connected, check all the wires, make sure everything is correct

            Make sure your crank position sensor and ignition wire refference sensor connectors arent swapped (under the diagnostic port)

                  You haven't got one.

                            Are you getting fuel firing out of your injectors?

                              well I figured out that my brother reversed the fuel lines. I switched them back and got the motor to run! but the starter seems to be running with the car as it idles which doesnt sound good. :?:
