And if it is the pump.. you need to see what caused the failure. Is the motor shot/seized? Is there trash in the head of the pump? Hose going to pump have an issue like blockage? Rot inside the pumps electrical connector?
Contact the mfg of the system and get some tech assist.
With a name that has the word "Hot Air" if you car is an 84/85 it will have a solenoid after the pump.. make sure the solenoid is not the problem.
On my kits.. there is a power injection bulb that comes with it and was suppossed to be installed on the dash, if the bulb lights up when you hit test.. then the controller "IS" sending power to the pump. At that point.. you need to go to the pump area and do some inspecting.
