Ya, the truck will run with a bad ring. I drove my TBI 305 1000 miles smoking with a bad ring and it would still start every 6 months for fresh gas.
Have you checked the fuel pump fuse? You can run a jumper on the oil pressure switch between the white and orange wire, should here the pump kit on, if not you have a power issue. You also have a brake out around the steering column. It is the harness going to the fuel pump, good spot to check for power. I have also found this plug unplugged causing failed fuel pump symptoms.
Oil pressure switch should activate around 4psi +/- a little.
