Hey guys. I have week long project going on. My protege won't start, it seems it isn't getting fuel, or the injectors all stopped working. I've replaced the fuel pump, pressure regulator valve, and filter. I can hear the pump humming when I try to start, and I get a spray of fuel when I remove the hose to the input of the fuel rail. If I spray starting fluid in the airbox, it starts and runs fine. But it shuts off after using all the starting fluid. How would I check if the injectors are working properly? The injector relay clicks when I try to start it, but it just wont start.

Check injectors with a noid light, if you do not get a response, then check injector fuse.
