2000 XTERRA 3.3 no start.

My XTERRA will not start. A couple weeks ago it
died and after a half hour it started. I drove it for 20
miles. No problem. Then while at a stop light it
died. After a few it started again. Heading home it
was cutting out  and bucking. I was able to reach
65 mph no pretty easily. Got it home did a code
check and had code PO335 Crankshaft position
sensor. Did some research and checked forums.
So here is what I did. I replaced the whole
distributor,cap and rotor. Replaced plugs,crank
sensor that's on the bell housing of the
transmission. Replaced the Throttle Position
sensor. Checked the power to the fuel pump and
the relay. Both good. Checked to see if the fuel
pump was getting fuel to the fuel rail by removing
the hose at the rail. Had plenty. Couldn't check
pressure cause can't find a port to hook my gauge
to. I have spark. I'm at a loss. Any help would be
appreciated. I can hear the fuel pump running
when I turn the key to the run position. If anyone
has an idea I'm all ears. Thank you. Also it's a 3.3
ltr motor. 4wd.
