Car was running fine, then next day it will crank but wont fire. Diagnostics returns codes 24 and 31. I have replaced the crank angle sensor and recapped the ECM. I am now at a loss as to what do do next and what I can test to see if there is a sensor causing the no start issue.

apparently you don't have MAF, or you have faulty part, or MAF wiring is fucked up, or mix of listed problems
why did you ever poke into CAS while having MAF issue?

Replaced the Crank Angle Sensor as it is a cheap part and since it is 24 years old why not replace it. Recapped the ECM because it also is 24 years old and the caps were definitely needing replacing. Tried MAF cleaner and got rid of Code 24 but still have Code 31, and now have ECT Power fault, which I have to check what coed it is throwing. Car almost started with the MAF being cleaned, so waiting on a new one to replace it. Not sure what you are referring to when you talk about the CAS.
