Crank sensor should throw a 19 flashes code (1 long flash = 10 + 9 shorts =19). It was hard to start a few times, turn the key off, back on, it would start. I finally spotted the code after a few times & got it fixed, no problem since. Be sure to look for the amber flashing code light. There's a thread on here as to how to read the codes..... I love these computers, they're so much smarter than I am ..LOL
