WARNING: This page is about a different car, the 2003 Mazda Tribute, 2003 Mazda B4000, 2003 Mazda B3000, and 2003 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Inspect fuel system for leaks and damage before testing fuel pump.

Perform the following checks:

Visually inspect fuel system (fuel lines, filter, pump, injectors, pressure regulator, etc.).
Ensure Inertia Fuel Shutoff (IFS) switch reset button is not in the up (tripped) position.
Ensure battery is fully charged and fuel-related fuses are okay.
Check fuel tank contents and fuel gauge accuracy. If any fault is detected, repair as necessary. If system checks are okay, check fuel pressure. See FUEL SYSTEM in BASIC DIAGNOSTIC PROCEDURES article. If fuel pressure is as specified, testing is complete. If fuel pressure is not as specified, repair fuel system as necessary. See appropriate SYSTEM & COMPONENT TESTING article.
