and turn the ignition switch ON (ll). The low fuel in-
dicator light should com€ on within lour minutes,
a lf the light does not come on, remove the access
Danel and disconnect the 3-P connector from the
fuel gauge sending unit, Connect the A

nal with a iumper wir€.- lf the light comes on, the problem is either the
sending unit or its ground.- lf the light does not come on, the problem is
