If you do get the engine running well, replace all of the old fuel lines on the rail and the injectors before too much driving. I smelled gasoline on mine one day while driving and when I opened the hood a tiny stream of gasoline shot by me on to the sidewalk. They dry out and crack lengthwise. The small stuff will eat up a lot of your time but it's worth it once you're done.

I’ve mentioned it some many times in the past about replacing each and every connector on the EFI harness and cleaning each connection in that arena. You will be amazed at the corrosion that you find on each connector and the wire itself. I had to shorten some wire by over an inch before I could find wiring that was suitable to crimp/solder.

The engine can run off puddled fuel in the intake manifold. If the injectors were opening the engine would continue to run. cgcheen's suggestion about testing with a 9 volt battery was a good one. You can run separate jumper wires if you don't have an EV1 connector. With a 9 volt alkaline battery you don't have to worry about melting wires if you accidentally short them. You'll hear a click when you connect the 9 volts, if they're opening. Also, with 9 volts you can leave the voltage connected while you tap them. You'll have the solenoid pulling them open if you can get them to break loose. Pin 1 at the ECU is the ignition signal that the ECU uses to monitor engine RPM. It's connected to the negative terminal of the coil. It should read battery voltage with the key on. But it also needs a certain type of voltage pulse. There are things that can screw it up. You're making great progress.
