Re: Injectors not opening after running out of gas
First thing I would do is remove the fuel pump relay and jumper power across the socket to turn the pump and let it run for a few minutes priming the fuel system.
Next, I would check voltage at any injector. One wire, black? will be battery voltage through a power relay for inj power after ign switch is turned to IGN. The other wire, black with a colored stripe, is controlled by the ECM and when ECM commands the inj to open, the wire goes low, maybe within 0.5 volts of ground, otherwise, battery voltage.
DO NOT ground the striped wire as it will break the ECM driver and a new/rebuilt ECM will be needed.
Use a digitial multimeter to check voltage on ECM wire as any other test instrument besides a 'noid light, will break the ECM.
ECM takes the Optispark reference and splits the signal into spark and injector pulses.
Another important point is check/clean engine grounds of all ECM devices and to battery.
Ensure battery is fully charged.
Might give the throttle plate a spray of starting fluid or WD40 to see if engine does start momentarily.
Ever crank the engine over with throttle to the floor?
Maybe others here will offer their suggestions.
