Hello. I drive a 2007 Ranger 2.3 XL with 5MT. Truck has 64k miles. Recently I have been having starting issues with the clicking sound when the key is moved into the start position. Sometimes the engine fires right up, sometimes I hold the key in the start position and after 4 or so clicks the engine starts. It is unpredictable. I replaced the battery last week ( it was 3.5 years old and leaking ) and installed a new starter/solenoid 3 days ago. The problem persists with the engine firing up immediately or just the clicking sound until it starts. Before I take it to a mechanic, could somebody offer some advice to solve this problem. It has to be a simple fix at this point. Ignition switch replacement? Thank you in advance.
