7. You are now going to relieve your fuel
pressure. The GM recommended way to bleed
the pressure is by installing a scan tool onto your
engine diagnostics port and commanding your
fuel pump relay off. If you do not have a scan
tool, refer to step 7. After turning your relay off,
start your vehicle and let it idle until the engine
shuts off (usually around 20-30 seconds). Turn
the key to the off position and check for little to
no fuel pressure. If fuel pressure remains in the
system, repeat this step.
