Holley sniper failure, this time its all bad.

Efi can be trouble free for 300,00 kilometers. Have seen it.
I think the name on my throttle body is holley. So dependability is there.
Perhaps sniper comes from the chinese division?
Im not big on the high horsepower fuel injection,but on mildly built engines they are nice.
When efi hit the street in the mid 80’s a lot of mechanics walked away. I know of 3 that left after seeing the service manuals.
