Drove car around it shut off threw crank sensor code replaced crank sensor. Still wouldn't crank. Found a wire came apart on pigtail. Bought new pigtail. Put old sensor back in cranked right up. Test drove got on it a little bit and service engine soon light flashing then went off. At idle it doesn't throw the ses light. Drove it to autozone it stayed flashing when on the gas it would stop flashing when at a stop then start again while driving. Autozone couldn't find a code does have a slight rough idle.

 

You STILL might have a bad crank sensor. Otherwise check all connections and grounds. Then see what's what.

 

I checked wires nothing I tried plugging my scanner in while driving didn't throw a code idk

 

How did you splice in the new pigtail...?

 

I took off valve cover it looks like the rocker barely hit it. Y wouldn't it throw the code at idle ,1st, 2nd but only in 3rd..
