WARNING: This page is about a different car, the 1995 Dodge Ram Wagon, 1995 Dodge Ram Van, 1995 Dodge Pickup, and 1995 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before testing is attempted, ensure fuel tanks are 1/4 full (minimum). Low fuel level (1/8-1/4) may cause poor performance and/or no-start condition.
