Fuel System: Notes

WARNING: This page is about a different car, the 1996 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT  allow fuel to contact engine or electrical components.
CAUTION: When battery is disconnected, vehicle computer and energy systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section before disconnecting battery.

Basic diagnosis of fuel system should begin with determining fuel system pressure.
