Have 91 SC has been running fine when some bolts holding pulley to harmonic balancer broke and others stripped out threads. Replaced Harmonic balancer and pulley, turns over but won't start. I assumed it had to do with the crank position sensor but when I checked for fire at the plugs I have spark. Noticed didn't hear fuel pump cycle when turning on key. Inertia sensor has continuity. Fuel pump relay hot wired and I have 40lbs of pressure. Spins over but doesn't try to start with 40lbs pressure. Apparently no juice to fuel pump relay and injectors? Checked high current fuses under hood, all have continuity and power to them. Any ideas on what to check next and how to check it would be much appreciated.
