Fixed

Jaybird,
I had my truck fixed by the dealership. I knew is was going to be expensive, but I was tired of running around the problems. Come to find out when I had my fuel pump replaced, the idiot that changed it out grounded out the wire to my trailer hitch ground. So all in all my fuel pump was continuosly running at about 85%, instead of changing when at idle, park, and driving. So far I haven't had any problems, they also said my #3 coil was going out, so they replaced that. Total cost was $330 for labor and $110 for the coil. I hope this helps, Chris
