The Calibra Fuel Pump Relay degrades over time, due largely to the
frequency of use and inadequate spec of the OE part. This causes the relay
to heat up during operation. Total failure of the
fuel relay results in a non-starting V6 - will turn over but never
fires due to no fuel supply.
Symptoms of a degraded Fuel Pump Relay are inability to restart the
engine from warm/hot (no fuel supply to rail) but when the relay cools
down starting is no longer a problem.
