Started with my low fuel light coming on, and my gas gauge going to empty...even when full. 3 or 4 time when I was doing several short trips, I would start my truck and all it would make a crank sound, then fade and would not start. If it sits for about 15 minutes...it will start right up. I took it to the dealer, got a new fuel pump, filter, line, and sensor...cleaned the throtal (sp) body...all was great for about a month, and today...the same thing. I also have a problem with my security light coming on...if I turn my key around, it usually fixes that problem. Almost $1000 worth of work...and all I get is my low fuel sensor fixed...please help...audrey

 

Its not unheard of to get bad new parts. Take it back to the same place that did the work. Sounds like you need to buy another key from them also.
