The quickest way to tell is: start engine and start cracking off injector lines at the pump. this will also tell you if you have a bad injector which one it is. This is not a big job but it is messy. Easiest to do on a cool motor.Also check for cracked injector line I have a 92 1680 and have blown n 3 line before. Also check condition of electric booster pump on bottom of fuel tank.
