i am really stumped
i am really stumped Ok i thought my opti was bad so i tore my car apart bought an opti and a coil...put my whole car back togeather and it started up but ran like absolute **** and sounded like it had a massive cam so i messed with it made sure my wires were in the right firing oreder so i figured ill buy another opti to see if thats it so i bought one from summit tore my car apart AGAIN and put th opti in put the wires on and put the sensors in and i tryed to start it and NOTHING i have no idea what to do ....it dosnet even want to start at all now...and after i was crankin on it to try to start it i walked back around and opened my throttel body and a lil smoke startin coming out of it so i dont no what to do...... PLEASE HELP ME any suggestsions need 
Sounds exactly like both the vette and the ss I've changed before. Ended up both getting the opti on wrong. The vette was a 93 so it was splined and the ss was a 96 so it was a dowl. On the vette I had to set the engine to TDC and aline it that way. On the SS I was just dumb and didn't get the dowl in its hole and It still went on. Now I always start it up before I put the waterpump on so I'm not tearing everything down again. Good Luck

Hey cruzin, this link should help you out with TDC. http://shbox.com/1/4th_gen_tech2.html#adjust_valves

There may be a easier way, but heres how I did it. First off I Got the engine to TDC(I used the thumb in the #1 spark plug hole method 
) Then I pulled of the cap from the opti base. I took a multimeter and placed the positive probe in the #1 spark plug terminal of the cap. Next I Took the ground probe and found the terminal on the backside of the cap that gave me a current when I sent a charge through it with the multimeter. So I then marked the top side of the cap where the terminal location was. I placed the cap onto the base and transfered that mark on to the base. Now I know where the rotor would be compaired to the base when its at TDC. Now I can mount the opti base with the rotor pointing the my referance mark and Its a sure winner ( took me a few tries to get it on the spline just right). Next just place your cap back on and button everything else up. Hope that long mess I just wrote helps any, but it worked for me.
