ABS help PLZ

Hi I have a 93 Acura legend that I'm having abs troubles with the peddle will just slowly sink to the floor then after a bit i will have to pump it real quick to keep the brakes the abs light on the dash is on I have from several people that you can pull the abs codes by jumping a lil blue wire clip on the passenger side behind the kick panel but when I do that nothing happens I was told to count the blinks but it doent blink it just stays on

Welcome to the forum.
Sounds more like a leaking brake hose or master cylinder issue.
Here is a link to a similar post (scroll to the 8th post.) I would
have it towed to a shop, rather than drive it.
Braking issue (soft,pedal to the floor)

Concur with Boru, a soft brake pedal going to the floor is related to the Normal Brakes (NB) system, not the ABS. The ABS is a complete different system, but it relates to the NB in our cars in mysterious ways.

My experience with such symptom has been a failing Master Cylinder (MC) unable to generate pressure due to deteriorated seals in the piston. If you are loosing brake fluid at the MC reservoir then you should try to track where is it going. If you see a trail of dirt or fluid under the MC, on the face of the Brake Booster (BB), BEWARE! It could mean fluid is being forced inside the BB and with the age of a Legend, it is very likely the brake fluid will also fail the BB. A failed caliper is another possibility, this can be checked by looking inside the tires, a wet rim is a good sign of a failed one. If you park the vehicle in the same spot every day, check for a brake fluid dirt spot for the leak will be in a brake line nearby.

Whatever you do, don't ever try to outsmart a Brake problem, and the soft brake pedal is a brake problem. It can be a very expensive and tragic proposition. Take it to a reputable mechanic, or get a knowledgeable person to properly diagnose it and fix it ASAP.

If your pedal slowly sinks to the floor, the MC is suspect. These boosters typically are pretty reliable, and need not be replaced unless they have failed. Boosters do not fail as often as MCs do. A very quick and simple booster test is given in the FSM. You do not replace a booster and MC as a pair, unless you want to throw a lot of parts and money at a problem. With Legends, that will empty your pockets very quickly.

An ABS Light in the panel "should not" be related to the normal brakes system. You need to get the codes for the ABS. At AcuraLegendWiki you can get the Service Manual and they have several articles that explain how to get them with details. Now, with the ABS codes the rabbit hole goes very deep.
