One problem related to diesel engine has been reported for the 1996 Chevrolet C1500. The most recently reported issues are listed below.
Engine would abruptly stop running. Failure was not dependent on vehicle speed, engine rpm, throttle position, or operating temperature. Shutoffs were frequent and came completely without warning. At any time, the engine could completely and unrecoverably shut down. Shutoffs were violent due to high compression of the diesel engine, and resulted in partial loss of braking and steering. Driving vehicle in presence of traffic would certainly result in an accident! failure was corrected through installation of a "pump-mounted solenoid driver. " I know of others who are experiencing the identical symptoms and conditions.
