1996 Dodge Ram Van 1500 Problems

Leak detection pump failure can be caused by the internal diaphragm switch sticking, or in some cases, contamination from debris or carbon particles from vapor canister.

Some vehicles may exhibit one or more of the following: Spark knock complaints when the vehicle is under load, various single cylinder misfire, and surge in 4th gear (around 45 mph).

An intermittent connection in the crank position sensor wire connector can cause poor engine performance or the engine may crank but not start.
