Ok so I had just started the truck 10 minutes before and the truck started fine. Now it doesnt attempt to even crank over. All connections are fine. I have checked all relays, tapped on the starter, then pulled the starter off and checked the wires and the + wire on the starter and it doesnt have any voltage when the key is turned. It seems like the computer wont let it start?
SOMEONE HELP PLEASE!

 

make any kind of noise? right now i can hear my solenoid click but the starter doesnt turn over..just been too lazy to look into it lol

 

yea. Lock and unlock the door with the key fob perhaps?

 

I have tried to lock and unlock the doors with the key fob, will try another key right quick. Got power everywhere just does nothing when trying to start, no clicks no nothing. Starter relay is fine.

 

Loose battery cable? Factory theft deterrent system cuts fuel just after the engine starts. So if it was that, the engine would start, then immediately die. No crank-no start is usually loose/corroded cable connection, starter relay, ignition switch, park-neutral safety switch, or starter.

 

Try putting the key on and cycling the shifter through the gears and back into park in case something with the neutral safety switch is going on...if that doesn't help I'm guessing ignition switch.

 

Only time ive had that happen to me, I forgot to plug in the safety connection thing on the driver side of the transmission.

 

Very good suggestion. Does the line under P or N light up when in park or Neutral. If that line isn't under the letter then it won't start and Would be PN switch. If it's there then likely the ignition

 

Yeah tried all the stuff with the PN switch, it reads fine also. Checked the switch underneath to make sure connection was good.

 

did you check all the fuse boxes?
