1998 FORD EXPLORER fuel pump

What you should do if the check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourCheck Enginelight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly installing and securely tightening
the gas cap. After three driving cycles without these or any other
temporary malfunctions present, theCheck Enginelight should turn off.
(A driving cycle consists of a cold engine startup followed by mixed
city/highway driving.) No additional vehicle service is required.
If theCheck Enginelight remains on, have your vehicle serviced at the
first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Fuel reset

turned to the ON position and the

intended to stop the electric fuel pump when your vehicle has been
involved in a substantial jolt.
1. Turn the ignition switch to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in the button on the switch.
4. Turn the ignition switch to the ON position. Pause for a few seconds
and return the key to the OFF position.
5. Make a further check for leaks in the fuel system.

FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause
severe wire damage and could start a fire.
