1996 GMC Jimmy codes come up on computer and cant figure wh

My 1996 Jimmy ABS light has been on, since I bought it. I can feel the brakes almost tightening up as I am driving, and then after turning it of then on again it loosens up and drives better. But the abs light remains on. I replaced calipers, brakes, rotors, cylinders. I had it diagnostically checked and it spit out these codes:

P0440-- EVAPORATIVE EMISSIONS CONTROL MALFUNCTION

P1886--TRANSAXLE SHIFT TIMING SOLENOID PERFORMANCE.

CAN YOU PLEASE TELL ME WHAT I NEED TO REPLACE TO FIX THESE ISSUES. ALSO DO THESE CODES HAVE ANYTHING TO DO WITH THE ABS ISSUE? I RELIAZE THAT I MUST HAVE THE JIMMY RESET UPON REPLACING THE NECCESARY PARTS / SENSORS.
IF I MUST REPLACE ANY PARTS / SENSORS--THEN WHERE WOULD I LOCATE THE PARTS / SENSORS ON THE ENGINE ITSELF? ANY ACCURATE HELP WOULD GREATLY BE APPRECIATED, MY FAMILY IS VERY LOW INCOME RIGHT NOW AND WE CAN ONLY AFFORD THE ABSOLUTE MINIMUM REPAIRS! THANK YOU AND HAVE A BLESSED NIGHT!
