When you say no power, do you mean you are testing harness AT pump? And there is power leaving relay ok?

Guess you'll have to bactrack the harness. Bein an 85, good chance for corroded plug somewhere or some other kind of damage to wring.

Check for power at the relay now from the wire from the fuse panel. With the relay is pluged in you should have power at pin 30 going to the pump.

Got power to the fuel pump now. Replaced the fuel pump with a new one. But now it won't start and the fuel pump does kick on. Cracks but no fire. What is your thought.

Is there a test port on fuel injection? Does fuel spurt out of it when opened? Do you have a way to pressure test? How did you get power to pump? So you didn't test pump itself originally?
