Just purchased an 07 5.9 auto with 110k miles. Today it wouldnt start fan and dash lights came on, no sound when turn to crank. Did it several times pulled key out, wiggled shifter and still didn't start. Then tried it again and it started up. Drove it home and cranked it three times. Wondering where to look when it does this again. Only had the truck a couple of days and this is first time it did this. But im guessing it will show up again. What should i look for or check next time it happens? Thanks in advance.

 

check battery cable connections, ytey could be dirty enough to not let current go thru!!
