I finished putting my sohc motor back in the car and tried to crank her up but no go.  The motor spins but doesn't crank up.  I have spark, fuel, and power.  My timing is dead on.  I did notice after cranking alittle bit that my cylinders where still dry (no fuel).  My fuel pump is good.  My injectors have power.  Im hopeing its not my computer.  The next thing to do is take it to the shop for a diagnostic ck.  Does anyone know whats up?   <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/butbut.gif" border="0" valign="absmiddle" alt=':but:'>

Is this a engine swap or did you rebuild your engine? I really dunno why it isn't working from what you said on here. Try looking back a couple of pages to reset the ECU to eliminate that problem.

While someone else trys to start it, put a mutlimeter on one of the injector's plugs and see if they are getting grounded. The computer grounds them to open them. They wont be constantly grounded, but should be cycled as you crank the motor which should show as something on the multimeter.
