Fuel Pressure Relief (TBI)

WARNING: ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT  allow fuel to contact engine or electrical components.

Disconnect negative battery cable. Remove fuel filler cap. Since these TBI units contain an internal bleed-down feature, system fuel pressure should dissipate after a short time.
