Mercury Optimax 90 hp 2005

I have a problem with vacuum at pulse line for lift pump at vst. I have good compression, I pulled intake to check reeds, they are perfect. I don't why I'm not getting enough crankcase vacuum/pressure to run pump. Please help. At this point I'm ready to toss in towel and repower.

Thanks,

Spencer
