New aftermarket MAF not working, likely or not?

[PaulRV6]

This is a new aftermarket Wells MAF that I tried and does not work, stalls as soon as I plug it in. What is the likely hood that it is no good? I believe I have read that it is more common than not. Thanks

From my experience, it’s a high likely hood of issues. My Wells coil pack and module was shit out of the box.

I’ve found it best to stay with a brand name like AC Delco or Delphi MAF & have never had a problem since
Just saying

I like to get newer style oem from the wrecking yard and use the translator with these newer style maf units. I've yet to get a usable replacement maf of any brand to work. Not sure why they are so hard to calibrate or what the issue is but they just don't work for some reason or other.
