I emailed the people at SOHfast .com and he tech that replied to me said that I can also get an Oil Pump from a 99-00 Civic SI and it would have the bolt holes for the CKF?

If that work, then I can do it two ways right?

1) Get a another ECU for about $200-$300

2) Get a Oil Pump from a Civic SI ($108 + Shipping) then CKF sensor for $130?

What would be easier, I never done this before, Changing the ECU or the Fuel Pump and the CKF?

I think the ECU may be easier...gosh im blabbling...
