So one day my car randomly wouldn't crank, I had to leave it at the gas station I was at, I planned to get it towed but when I returned it fired right up. It had been doing this for like a week until it finally wouldn't crank at all. I've narrowed it down a little bit, the starter is fine because if I jump the starter relay the starter cranks but it doesn't want to fire. Although it will fire after many attempts ( never did this before) but it seems if I start it that way it messes with a lot of things because my abs light and bas light go on and other weird things. My guess is because I'm bypassing some modules when I'm jumping the starter relay on the k40. I was wondering if anyone could point me in the right direction to help find the problem. Thanks
