I need help with this guys...i was driving home with no problem..all of the suddent the truckjust shut off by it self. I tried turning the truck back on and it wouldnt turn on. Then i notice the check engine light was on.. It also drain my battery to fast...like in 20min..i was told that the crank sensor goes out on the those trucks?? Can someone help me on this...oh

 

check the code for the check engine, it will tell you what is the problem. ( you need a scan tool OBDII, if you do not have one, or have no way of barrowing one, a cheap basic one for about $50-$80 will do. (a mechanic will charge abot $100 to do it, so you do the math). check your local craigslist as well you may find one real cheap.

anyways
my guess it is a fuel pump

 

Autozone can do it free, if you can get it there. My 07 wouldn't start one day. I have an aftermarket ecm that throws codes. So I put my stock one in to pass inspection. Switching back I didn't disconnect battery. Luckily warranty covered it. Anyhow, on these newer vehicles try disconnecting and connecting the battery.
is it turning over at all?
