i'm not too sure...

ok, the trouble code that is showing up is "51". from what i could find out 51 means eaither the airconditioner switch or the neutral start switch. i have the R154 tranny so i don't have to worry about a neutral switch. but could an A/C switch really be causing my problem??

^^ True...OP, you said the "timing marks were dead on"...guessing you mean cam + crank timing...but did you check the position of the CPS when #1 piston is at TDC? This write-up might be helpful: http://www.supramania.com/forums/showthread.php?38775-How-To-basic-timing-instructions-CPS-alignment

ok i'll check this out, thanks

If the A/C button is pressed while you're checking codes, then yeah, it will set a code 51. Same thing if the throttle isn't closed (your foot is on the gas pedal or it's somehow stuck partway open). Other than that, a code 51 points to the TPS or TPS wiring.

ok, the trouble code i'm getting now is the "camshaft sensor signal" i did a compression test and i'm actually getting compression. what do i do?!
