2012 6.2l Not Starting!!

[Remoat]

If the starter isnt getting a load applied during test it my not be reproduced. I had a starter passed all the autozone tests and still couldnt turn the engine over. I replaced the starter and all good. I believe relay or fuse 27 is fuel pump related. Should def turn over if that was the case. Good luck, this will bring you and your rap closer....

Check all the connections at the alternator, starter, and inside the fuse box for corrosion. Any one of these connections gets corroded and all manner of weird stuff can happen. Good news is that it'll only take about half an hour with a wire brush and a can of aerosol terminal protectant. Cheap fix.
