Model Year Affected: 1997

Engine Affected: 3.5L V6


A defective fuel pump check valve (which maintains fuel pressure in the system when the vehicle is not running) may lead to long cranking times or hard starting (sometimes with stalling). The fuel pump should be replaced. However, if these symptoms are accompanied by Check Engine Light illumination, there may be a problem with the engine coolant temperature (ECT) sensor.
