I don't see why replacing the blower motor would cause that but have you checked to make sure you have fuel pressure the easiest way is to turn the key to the on position and you should hear the fuel pump hum the tank and to be even more sure there is a bleeder valve on one of the fuel lines that run into the intake behind the throttle body pull the plastic cover off the valve and push down on the rod in the center if fuel shoots up your getting fuel also check the in line fuel filter on the inside of the frame under the driver side door...

Reason I included the blower motor is because the ECM is directly above the blower motor. Thanks for the help!
