My cousins 2006 is dead on the road we pulled the ABS fuse tried to start truck no start...replaced fuse tried to start no start.... truck turns over but no lift pump or CP3 pump noise and the red light on the dash is doing erratic flashing...... truck is stock 2006 laramie....... whats going on..... by the way its a long story why we pulled fuse and tried to start

 

the red light is the security light........that would be weird if the ABS code locks it up??? kinda sounds sentry key related??

have you tried unhooking both neg battery cables for a while????

 

No I dont think we did how do you reset the security?????

 

???????? I dont know.......

 

Lift pump??? Pull the fuel filter and drain the reservoir. Then put the fuel filter back in and try starting it.. THen pull the filter again if there is fuel in it then it's not the lift pump if no fuel lift pump is shot.. Let me know

Don't know what's up with the red light??

 

Aight thanks for your help guys were at a party so im out...... Ill post back tomorrow with results but right now Im leaning toward shot lift pump.......

 

Any word???

 

This sounds completely electronic. I'd pull the negative cables also.

 

I think that little red light is the security light. (check the owner's manual). If it is the truck is locked from anyone starting it. Did the truck just die while running or was stop & now will not start?

If it was stop & now doesn't start, try the key fob with locking & unlocking the doors & then use the key again. Otherwise you may have to call a dearship ... Its still under warranty.
