Everthing was working fine through several trips to town for wife to shop. At last store we're nearly done and turn the key - nothing! All lights are on with no dimming or clicking noises. Battery checks fine, terminals are clean and tight. Tried both Park and Neutral. Had to have it towed home. P0335 code appears alongside a previous P0327 that has been there for awhile. Neither of them will erase. Starter fuse looks fine. Going to check the starter relay next. It's the 4 cylinder model. Any suggestions for what I can do before getting it towed to a shop in town? Thanks!
