Pegged out speedometer

[mort]

I replaced my stock lift pump with a fass 95 pump along with getting my A/C charged, and installed an edge juice with attitude monitor today. When I got in to take it for a test drive I noticed that my speedometer needle was pegged against the at rest nipple on the back side. If I shut the truck off and after a while the needle will rest back to about the 7 0'clock position, as soon as I open the door it pegs out again. The only trouble codes that come up are P0628, low voltage detected at fuel lift pump. Could this be from the chip or a loose connection? I tried to wiggle all of the new connections and no help. I own a 2003 4x4 six speed with 92k. Every thing has been stock to this point. Thanks for you help and input.

Check all your connections carefully to make sure all are sound, grounds are sound, and all new wires are connected to the proper terminals or wiring

Thanks for your replies. I figured it out finally. I had the dash out prior to that checking the a/c to find out why it would not blow cold air on the passenger side thinking that a vent door had broke again. It turned out to be low on freon easy fix. When I had the dash out the gauge cluster go turned upside down and allowed the needle to spin all the way around with out me noticing it before I reinstalled it. So I removed the cluster and turned it upside down to get the needle on the correct side. As for the DTC 's that the truck ran they came from connecting the injector nozzle connections in the wrong order when I installed the chip. Never would have guessed the the sequence was that important. All is fine for now.
