HI!
This Morning I started my STOCK truck and the check engine light came up. I tried to do the key thing 3 times with no success. Do you turn the key until you hear the pump? Where do the codes show, in the dashboard or the overhead?

 

You want to cycle the key fast 3 times and leave in on position the third time. Do not come all the way back during the cycles and that should show any code or if none it will say done.

 

Hi Ronc!

Will this show in the overhead or the dashboard where the odometer is housed?

 

On the dashboard.

 

Thank you.

 

Guys,

I did the key thing and I got P0191-Fuel Rail Pressure Performance. Can I still drive the truck til' Monday morning? That's the only time the dealership can see it.

 

When's the last time you changed your fuel filter? It could be the problem. I've had the light come on and after changing the fuel filter, the light will go off after driving it a bit.
