Hard starting due to leaking fuel pump check valve on Chrysler LHS

Problem Description and Possible Solution

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.
