Problem: While the owner was driving around
town, the engine suddenly died. When she tried to restart it, the
starter would not crank the engine over. Additionally, she heard
clicking noises from under the hood.
Details: The technician noticed that the
starter would crank when battery power was directly applied to
the starter solenoid. He also noticed that the blower motor and
fuel pump relays were clicking constantly when the ignition
switch was in the ON position.
When the technician called ALLDATA Tech-Assist, the consultant

IPM tested good, then the logical conclusion was that the IPM was
Confirmed Repair: After the technician
replaced the IPM, normal electrical system operation was
restored, relays no longer clicked and the engine started and ran
normally. Problem solved!
