I would probably have the computer scanned for ABS trouble codes.
It could be a switch or something else such as an actual problem with the abs system.

i would check the ground strap to the block. it may also be that your battery is too weak to start that high torque motor. check the cca ( cold cranking amps) of the new battery,making sure it is at least 1000 cca - anything less and it won't have enough oomph to kick it over. have you felt along the length of the battery cables for lumps/bumps ( that spells a bad cable). there is a possibility it is the mechanical ignition switch, which is mounted on top of the steering column under the dash,but i wouldn't suspect that as it does start with a jump.i would also check where the negative cable mounts up - there could be corrosion hidden there. corrosion ( green or white deposits in the cable, terminals or connection points) increases resistance, which means it will take massive amps to start. with the christmas tree lighting up, i would first suspect the block ground strap, which is a braided, flat wire that goes from the block to the frame or body.
best of luck and i hope this helps!!
