I have a 2016 Ford Escape SE that will not start on some days but then on others it will start just fine, like today it started just fine after sitting all night but when I was leaving work to get lunch it took 4 times to get it started. When it does the no start it makes a single click, I will retry to start and it’s sluggish to crank but will eventually. I just had the battery tested and it tested good and the alternator tested good as well. Battery cables have been tightened down and cleaned of any possible corrosion.
Any help would be nice. Thanks.
