When I drop the tank to do the fuel pump I forgot to disconnect the pressure switch and cracked it on the outside at the base. Can I bypass that pressure switch. And will it cause the motor not to start pump primes doesn't seem to run. I bypassed relay run a fuel pump still no start probably combination of. Fuel pressure center on fuel rail squirted gas when remove vacuum hose assuming broken diaphragm and broken fuel tank switch. Will a tank switch make the car not run fuel pump relay was bypassed, still no start?

That's the pressure regulator switch. Is there anything I should know about taking that off that I don't assume by looking at it? Intake manifold have to come off question 1.
