Truck acts up drivin down the road the radio cuts on and off when accelerating the lights are dim and then get bright and go back dim.... When I park the truck the batteries die and won't crank back unless I jump it off it's like there is a short somewhere that's killing the battery but I also have an edge juice programmer on the truck could that be it?

or autozone. i made the mistake of getting one there. had a alternator for a month and it crapped out. pay the big bucks and get a good one or a mean green machine 220amp. a good test is unhook ur batteries while the truck is running, if it the truck dies ur alternator is crap.

Replace your batteries and alternator, before you damage your ficm. You probably already did. Oem eqiupment is fine if you maintain and monitor your truck. Putting a huge alternator is not going to matter if you run your truck to failure. Get a monitor on that truck!

It shifts just fine... Once I jump it off it runs just fine how would I know if ficm is bad?
