First you need to get a really really big metal crank, usually looks like a key, to insert into the front of the vehicle... No, no wait, my bad that was a 1903 Chevy Silverado.
No, but really, they don't crank. They turn over. And if that's the case, it's probably your starter, you can go buy a Chilton's Auto Manual and do it yourself, or you can take it to your local mechanic.
Check your crank shaft sensor
I was told it could be bad fuel pump.
modual
Check your coolant. Is it thick and gunky?
wont kickdown into passing gear
Do you have automatic locking hubs on the front axles?
the truck will not crank or anything with the key it wont even starter when you ark the starter all it does is whizz
Bad temperature sending unit? Bad gauge?
Bad transmission? Bent shift linkage?
try the fuel pressure regulator
this happen to me and turned out to be corrosion on battery terminal, clean them very good.
