91 GTI 16v swap won't start
 

so the other day i was at a stop light and it just died and wouldn't start up again. it will run if you spray starter fluid in it, but the fuel injectors and fuel pump won't run kick on at all. i've check out the sensors and they all seem to be fine, i even hot wired the fuel pump and injectors to come one and it still won't start.

so what all would keep the fuel pump and injectors from coming on? bad ECU? any other ideas on what i should check?
