Re: 84 coupeD 4.1

Shorting the injector wires may also damage the ECM. Good thing to watch for when installing the air cleaner.
There is a tee in the fuel line going to the throttle body, for checking fuel pressure with a gauge. You would need to adapt a fitting/hose to it and remove the valve core in it for a simple pressure test. 9 to about 12 PSI in all engine RPM ranges is normal.
Any old gas in the tank?? It could have a lot of gunk in it. The fuel filter is usually under the driver-side, toward the rear.
