Fuel System Pressure Release

WARNING: This page is about a different car, the 1995 Isuzu Trooper. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Fuel pump relay is located in engine compartment fuse/relay box.
  1. Loosen fuel tank filler cap to relieve tank pressure. Remove fuel pump relay from underhood fuse/relay box. Start and operate engine until it stalls. Crank engine an additional 30 seconds.
  2. Loosen hose clamp of fuel line on side of pressure regulator, coming from fuel line inlet distributor pipe. Cover fuel hose with a shop towel, and slowly pull hose from pressure regulator to relieve fuel pressure. When fuel stops leaking, reinstall hose and clamp.
