i have a93 z did msd coil accel 8mm wire and bosh plugs and i took off the distributor cause i didnt think a msd would cost 500 bucks so i put the old one back on and now she almost fires but doesnt start and now im stuck any help please and thanks

 

double check the wires to make sure you got them in the right places. then check again. make sure they are on all the way. including the coil wire. check all your plugins that are in the area of where you have been working.

 

can an unvented opti be installed incorrectly? It sounds like timing is way off

 

only if you force it. theres a gear missing in the sline of the shaft.

 

how did you post at 442

 

No, there's a notch in the shaft. The only way you could put it on wrong is if you forced it with a sledge hammer.

 

How did you get ahead of me? I think we have a time/space continuum problem here!

 

yah and i posted twice in there and deleted them. i asked how you posted at 442 when it was 440. there i undeleted one.

 

i just put the old coil in. no start put the gas pedal all down and a flame came out the intake can anybody give me a wireing pic i used alldata for the diagram maybe thats wrong

 

you most likely have a couple plug wires crossed, its not hard to do even using a diagram.
