Location of Fuel Pump Relay - '94 Winnebago - WHERE??

First suggestion,stop throwing parts at it,second if I understand you corrctly it fires on starting fluid that means you are not getting fuel so the next step is to see if the pump is running. If you get under neith and have someone turn on the key can you hear it? If not get a meter and check for power to the pump.If pump is running then get a noid light and check for power to the injectors.
