I did some updates, cleaned injectors, replaced plugs & wires getting ready to get it tuned. After updates started car up backed it outside to adjust fuel pressure. it ran fine for approximately 10 minutes while I adjusted fuel pressure and verified PCV operation. Shut car off to remove test gauge from fuel rail went to restart the car and when I turned the key on I didn't hear the fuel pump come on and the starter spins but car wouldn't fire. Reinstalled test gauge and had no fuel pressure. grounded LB/O wire in the test plug under the hood, pump did not cycle. checked power in & out of inertia switch have 10 volts in & out. Any way to apply power to pump without getting under the car?
