1990 Honda Accord will start / then quits

I REPLACED FUEL PUMP. THEN I WASNT GETTING ANY SPARK FROM COIL.SO I REPLACED COIL AND GOT CAR RUNNING FOR ABOUT 20 MILES,THEN CAR STOPS AGAIN AND WOULDNT START BACK UP.IT WOULD TURN OVER FAST,BUT NO SPARK FROM COIL.SO I WAITED A DAY,AND WENT BACK TO TRY AGAIN.PUT THE DISTRIBUTOR BACK ON,HOOKED UP WIRING,AND CAR STARTED AND RAN FOR ABOUT 20 MINUTES,THEN JUST CUT OFF BY IT SELF AND WOULDNT START AGAIN. I CHECKED THE MAIN FUEL LINE TO THE INJECTORS AND NO GAS PRESSURE THIS TIME,WHEN I OPEN THE SCREW ON LINE!!! I HAD TO REPLACE BATTERY DUE TO BAD CELL. ANY SUGGESTION,WOULD BE APPRECIATED!!
