So I spent the last two days replacing my clutch. Man was it toast. Anyways to my current issue. I have everything together and the car won't start. O2 sensor is hooked up. reference sensors are back in. The distributor cap and wires are all on. Can anyone think of why it won't start? I am a little frustrated after spending all the work and the engine doesn't start when I wasn't even doing engine work.
I replaced my flywheel with a Fidanza and put in a centerforce clutch. I don't know if that means anything for why it wouldn't start. I will comment and say I noticed the little screw on the side of the flywheel. Is it possible that needs to come out more for the reference sensor to read it?

You don't say what kind of car you have, but I'm assuming it's a 944. I've got a 968 that I'm struggling with a no-start problem on as well. Based on the fact that you just changed your clutch and flywheel, and didn't do anything with your engine, I have to assume your problem is with the reference sender. Did you set its gap to 0.8 mm (at least that's whit it is for a 968 - you should check what it is for your car)? Do a search, as I know there are several threads that explain how to do this.
Does your tach needle bounce as you try to start the engine? It should, and if yours doesn't, it's more evidence that the problem is with the reference sender.

Sorry I have a 85.1 944. to be honest I don't know if the tach was bouncing or not since I tried starting it at night. I can take a look at that tomorrow morning. My engine was running fine before I changed my clutch. Also it turns over just fine. I have a feeling it might be the reference sensor.What would be better to adjust the gap the mount or the little hex screw on the side of the flywheel?

On the 944.1 there is an electrical connector somewhere over the brake booster area which can pull apart when you lower the engine. This may disconnect some vital systems.

If the tach needle doesnt bounce when you crank the motor over its in the ref sensor. Or you could have the connections crossed between the ref and speed sensor

So this morning I discovered the speed and reference sensor needed to be switched I also measured the hex bolt and loctite it in place. I am waiting 30 mins before I try to start this car. I guess sometimes after working on a car 12 hours straight you just need to get away and sleep to fix the little things
Wish me luck!

So it started right up. However it wasn't just swapping the two sensors. because I had tried that last night (twice) and it didn't start. I ended up having to bring out the hex bolt on the new flywheel to match the original one in there. It was about a 1mm off. It was so nice to drive the car again. And there was no more jerking motion when I lift my foot off the gas!

So far driving it around for 50 miles I would say I do notice when I push the clutch in while driving the engine speed drops quicker. But it does not stall like I have read some people state. Take off on flat land fells normal. Starting on a hill I have to rev a little more than normal but then again the clutch is being broken in. I do like the feel of it around town. Has that effect of feeling more responsive.
Other things I have done to my car as far as reducing drive train weight/drag are, removed power steering and pulley, removed ac, removed the mechanical water pump and installed an electric one, removed balance shafts, installed lower gears of the alternator. Needless to say I like how responsive my engine is, still need to install a throttle cam.
