When your battery died, possible engine programming was lost, this is called KAM.
need some info, what kind of kit was installed, and did it require any programming when first installed?
Also important to know, is did this problem happen right after the battery died, and it was jumped?
okay great information, let me research the parts,
also, when you step on the accelerator, do you get nothing at all?
not even trying to raise engine speed and missing?
okay, would like you to do me a favor, remove the intake tube that goes to your throttle body, and see if the throttle body opens when hitting the accelerator pedal, try this key on with engine off and engine running as well.
Any check engine light on when the vehicle is running?
