one problem fixed new one pops up
So I finally fixed my fuel pressure issue. Fuel pump was going. Replaced the Walboro 255 with a 400. Then I get the service traction and ABS message with codes, C1214, C1221, C1222, C1241 and a C1248 that isn't even on my list of codes. Anyone? I truly don't think I care if ABS works and I never used active handing but is there more to this then just the two?

C1248 is telling you that there is an issue with the DRP (Dynamic Rear Proportioning) valve. According to the shop manual that codes gets set when both wheel speed sensors on an axle are out ( In your case C1221 and C1222).
The wheel speed sensors themselves seldom fail. The issue is usually with the wiring to the sensors or the contact surfaces of the connectors that connect the sensor to the car wiring. Pull the front wheels and inspect the wiring and repair as necessary. Separate the connector halves and check for corrosion or mal-formed surfaces of the contacts. Repair as necessary.
C1214 is usually the main power relay on the EBCM. Either repair yourself or contact any of several repair places like ABSFIXER .

So just got back from driving it for a bit since this happened and I drove hard on and off. I dunno when it happened but I looked down and abs light off and no more messages. Does it usually clear itself? I am sure it will come back. Just strange.

Actually I remember reading where going to some spirited driving especially in figure 8's can "wake up" the ABS/AH/TC systems..

once it rears it's head surely it will come back again at a later time... if your car is an 01+ I would just go ahead and repair (or replace if necessary) the relay in the ebcm... usually it's just a few bad solder joints that you need to repair and overall it's a pretty simple job... mine threw some abs/tcs codes a couple of years ago and they went away for some time then came back last summer but this time they would not clear, even if I tried to manually clear them they popped right back up... resoldered my relay and it has worked fine since
