I have now run into a problem I can't solve. I drove the car into my garage a few weeks ago to do some minor maintanence. Oil change, brakes, swap tires new battery, etc. It will not start anymore. Changed distributor, ecu, checked fuel pressure, spark good. It appears that the injectors are not getting the signal to start pumping fuel. Car will start if I blow in starter fluid. Definately a fuel / injector problem. I don't believe the injectors are getting the grounding signal. Does anyone have any ideas on what else I could check? Thanks in advance for your help.

This is an 87 Celica with 2.0L 16 valve 3sfe motor with 5 speed trans.
