Default TBI Injector Pulse

I have a 1989 5.7L TBI that will not start. There is no fuel spraying out of the injectors when the engine is turned over. I've done some reading and checked the following things:

Ignition Control Module-had this checked at Autozone 6 times and all checks passed. The guy said it was getting nice and hot.

Pick-up Coil-I checked the resistance on this and it was 788ohms, which I understand is good? The plastic connector on the pick-up coil was crumbling and the leads to the coil may have been arcing out to the plate under them. I sealed up both leads with heat shrink tubing to isolate them.

Spark-I have a good white spark from the coil wire to the distributor. The spark at the plugs is orange. Cap & Rotor???

Fuel Pump- I can hear the fuel pump turning on when the key is turned and I am getting some fuel pooling on the top of one injector by the wires. I think there is a bad o-ring.

Does anyone have any advice on what else I should check?
