Aircraft X checked onto Departure and was instructed to 'Climb via SID' on the MNZNO3 Departure CME transition. Aircraft X read back the correct control instructions. While on the SID; Aircraft X passed south of the point where they should start their climb but remained level at 90. Approach caught this and asked if they were 'Climbing via the SID?' Aircraft X replies they were given 90 (previously on clearance delivery). If Aircraft X were to remain on the SID they likely would not make the climb over the eastbound turn MVA of 113. As a result departure took Aircraft X off the SID on a 190 heading; and they were then instructed to maintain FL200. If Departure was busy and did not catch Aircraft X leveling off at 90; they would have turned east into an MVA of 110. Aircraft on clearance should be instructed to 'Climb via SID' with no altitude restrictions; and if approach needs an altitude restriction this will be given upon aircraft check in. - OR - all pilots need to be on the same page that when Departure clears an aircraft to 'Climb via SID'; this deletes the clearance delivery restriction previously given.
ABQ TRACON Controller observed aircraft not climbing; questioned pilot; and issued Climb Via instructions again.
