Chasing my tail, need help badly.

[Luckyman01]

The top line is that I have a crank/no start.

I have a 2000 Boxster S.

The fuel pump is not running when I turn the Key on. I replaced the relays under the dash and back in the trunk. I also replaced the ignition switch. And the CPS sensor.

I did have a PO455 code last time she ran.

Too that end I replaced all the valves under the right front fender (all 3) and the purge valve under the left in take manifold.

I have inspected the SAI vacuum hoses and have not found an issue.

At this point I have no idea what to do and done for now throwing parts at the old girl.

My wife thinks that at age 70, I may of lost my clarity and should give up and have it hauled to a qualified mechanic.

However I live on the southern Washington state coast, ~120 miles from Portland and a little further to Seattle.

I need some kind advice ASAP

Thanks,

David
