-Truck was parked at airport for 3 weeks
-smarty not installed
-tried to start truck
-batteries were a little low but turned over enough that it should have started
-then batteries likely only lasted for another 30 seconds till dead
-noticed shift indicator lights were not lit.
-tried to read codes with smarty but it would not comunicate
-unhooked batteries,recharged both,checked all fuses,tried different key,still no start.
-towed to dealer
-they could not communicate with commputer either.
-replaced main computer,still no communication
-replaced whole fuse panel box under hood(some plug pins were corroded off on back of box)
-still no communication.
-they then walked away confused with the battery cables unhooked and recharged the batteries.
-2 hours later they came back hooked up the cables and they had full communication(not sure why)
-noticed shift indicator lights were back on
-reflashed computer with newest flash
-truck started right up
Nobody is really sure what happened or why. Truck seems to be working fine now . It actually seems to be working better in stock form now then it did before. I just need to get my smarty back in it.
There might have been some kind of electrical glich, my isspro trans temp guage was flicking all over the place for about a month before this happened and now its working perfect.
Thanks for the replies,Rob.
