I noticed a few days ago that I'd have to turn the key a couple times for truck to start. Would eventually start... Then suddenly, not at all. Only a very faint click... When key in (acc), all lights work, full power, etc. Then I tried using the clutch override and it starts right away. I'd thought I needed to replace the starter, but now I'm not so sure. What could this mean? Thank you so much for your advice, (in advance), I'm a bit perplexed.
