3vze no spark

Having some issues with my 3vze I know it’s getting fuel and I know it’s not getting spark. tried the whole pull the mas and still won’t fire! I’ve tried looking for grounds but can only see the one from the valve cover to wheel well on drivers side any other lil tricks would be great

What else have you checked? No spark at the plug, so go up the line. Wires ok? Distributor ok? coil/igniter ok?

its got no spark at the plugs and seems like no power to igniter.
Not seeing the check engine light when I turn the key not sure what that’s about or if that helps ?

Well, you don't have a Mass air flow sensor. You have a Volume Air Flow sensor (VAF). Different technology.
Still, what does "tried the whole pull the" Vane Air Flow sensor mean?

First, tell us what you're working on. Wiring, component location, etc. is sorta consistent year-year, but there are differences. Park it all in your signature and you won't have to keep repeating it.

Complete lack of CEL (should be solid with key-on, engine-off) is probably due to no power to the ECU. Check the EFI fuse. Use a multimeter (there are metal tabs on the tops of all ATC fuses for just this purpose), so you don't get fooled by a "slightly" open fuse or loose fuse holder.
