several seconds, check the fuel pressure. If there is no fuel pressure, turn the ignition key to the OFF

Repeat this ignition OFF and ON procedure until the fuel pressure gauge registers fuel pressure.

around the Aeromotive regulator and all fuel lines and connections near the regulator! If any
fuel leaks are found, turn the ignition key to the OFF position, remove any spilled fuel and
repair the leak before proceeding!
