2000 Chevy S10 No start

Okay..this is going to puzzle some brains. I have a 2000 Chevy S10 2.2 that will turn over but not crank. I have replaced the coils,ign module,plugs,crank sensor. I have 45-50 psi of fuel pressure while cranking, and around 43 just turning the key on. I have 140-150 compression on all four cylinders. I am showing no codes. All my data is within specs. I have sprayed the throttle body with ether, and still will not start. There are no security issuses, and does not seem to have any computer errors. It will try to crank with WOT, but to no avail. I know that WOT will shut the injectors off. I also have a good strong injector pulse, (test with my noid light). All the components are there to make this thing run, but cant get it to. Could this be a possible timing issue, i dont believe so because of my compression is strong. Any help or ideas would be greatly appreciated. Thanks, Rusty oh yeah..i do have spark

" that will turn over but not crank" ?
"45-50 psi of fuel pressure while cranking"

you lost me there. Did you mean will turn over but not start up?
Is this a motor you rebuilt and placed in the vehicle yourself? and Yeah this has me puzzled too.

Is this a code 4, or code 5 [flex fuel] ? I think the flex has higher fuel pressure requirements.

Re: 2000 Chevy S10 No start

do you have spark? have you manually checked if the wire is sending power to the plugs?
