If you're experiencing fuel delivery problems (car won't start, sputtering, etc.), you'll need to troubleshoot these potential causes:
* Check the fuel pump fuse: Consult your owner's manual to locate the correct fuse and check its integrity.
* Check the fuel pump relay: Again, your owner's manual will show you the location of the relay. You might try swapping it with a known good relay of the same amperage and type.
* Inspect the fuel pump wiring: Look for any broken, frayed, or corroded wires leading to the fuel pump.
* Have the fuel pump pressure tested: A mechanic can perform a pressure test to determine if the fuel pump is delivering adequate pressure. This is often the most definitive test.
* Consider the fuel pump itself: If all else checks out, the fuel pump might be failing and need replacement. This is a more involved repair usually requiring professional help.
In short: Don't look for a reset button; instead, diagnose the problem systematically. Ignoring a true fuel pump malfunction could lead to significant engine damage. If you are not comfortable performing these checks yourself, take your Aztek to a qualified mechanic.
