Default Finished mpfi conversion.. but getting codes 7 & 9

I finished mpfi today.. on my 91 dx, using d16z6 manifold. Ive checked the ECU and im getting a code 7 and code 9. I know that i am getting the TPS code because i dont have one plugged in, its in the mail. But im not sure why im getting the #1 cylinder position error code. Can anyone enlighten me on how to check / fix it? thanks

EDIT: search owned me. sorry for making this thread

check crank angle sensor w/a multitester at the plug. check continuity to ground w/the four prongs that form a square. should be 350 to 550 ohms. what distributor are you using?

its d16a6 Si dizzy.. as far as sensors .. the tb on my manifold didnt have map sensor, so i used my stock dx map and evap purge selenoid... i also used my dx IAT, and a z6 EACV. the trickiest part was that i needed to plug the small coolant nipple underneath the runners closest cyl #4

Did you just plug the nipple or did you run a line?

i plugged it using a piece of hose, a bolt, and 2 clamps. although it would be possible to run it and t it into one of the others... whichever u choose i guess!
