Having this issue since last year. Has been to the dealership twice since last year. Had the neutral safety switch replaced and did fine until march of 2018. Then it started again. Only at different intervals. Might crank, might not crank. Next day it cranks. Just got it back Tuesday and it's doing ok, but what can be causing this? I have a feeling I will be stranded again. It will not do this while at the shop. I went ahead and had the "defender" anti theft control completely removed. Plus I had some other issues not related, all fixed. But since they had to unhook the battery everything seems fine now. Do I have a computer issue? When it 1st happened. I could pop the clutch real hard to make it crank. But I think I have a relay issue? Thanks for any help with this.
