I don't like the .96x. Looks like you don't have any broken wires. I thought you already replsce the cs? Damn confusion. You've replaced everything els and it seem like your wiring is ok. It's only 15 for a cs. With that .96 (I don't understand that)I would replace it. If you replace the cs ohm it again and see if that "." disapears.

Yea im confused,  CS is crank sensor, KS is knock sensor right?  My crank sensor is brand new and my knock sensor is old.

But a KS wont stop a car from starting, at least last time I checked. So lets just quit talking about that for a min. A .961 tells me that the Multi Meter is on the wrong setting. on the 2k setting you should see no point at all, or it to be on the very far right for no numbers after it.

3 things are still coming to mind on this.

First the ECM. Its one of the few things you havent replaced yet, and something is telling me to take a look at it. Dont know what, just something tells me to look at it..

Second, you said the longer it kept running, the worse the running engine got. Sounds like its going from a closed loop to a open loop mode (might have that reversed). which leads me to beleive there might be a timing issue.

Third, To eliminate all posibilitys, try swapping the injectors back to the 3x00 stockers. Dont drive it like that, just see if it will start. Obviously they dont have the right flow rating, and could potentially cause damage if driven. But for idling purposes, I dont see a problem.

Just my humble opinion.

What was the problem?

By the way, I have replaced my CS twice within two years, so it is NOT unheard of for a new one to go bad.

Thanks Bro. 

A couple things were actually going on, i didnt know the map sensor plug was cracked because the tgp harness is pretty tight in there.  Fixed the map plug , put some fresh gas and it started up.   It sounds pretty weak when its idling but does sound pretty cool when u give a little rev...... blows some black smoke at idle.   Dies out in drive and has real weak low end power.  Need to get hooked up to computer.

OK heres an update: The car starts up on its own. I think i have an injector problem now. The car runs like it has clogged injectors. If anyone here knows what a 3.1 feels like with crappy injectors, this is it. I think i tried starting it too many times not knowing there was no gas in it. ( my gas gauge is decieving). I figured this out because instead of gas, i was getting air out of my fuel rail . Put gas in a primed the air out now the car runs but i think i screwed the injectors up. This sucks because now im thinking about mail the injectors back and having them ultrasounded or flow tested. The car lacks power all around but does run and rev. Idle is weak as hell and sounds like theres a potato in the tail pipes haha. Anyone else think i coulda screwed up the injectors now? Thanks!!

I've heard of 3.1 injectors dying because they got too hot, so its a possibility..... take the injectors and ohm them out- I'd start with that.

This part sounds very similar to the problem I am having, doesn't idle well, but unlike yours doesnt like a little rev either, weak low end and dyin out on the road while driving. You might have seen my post right below yours, I got the injectors and map sensor comin in hopefully today, and am going to try them, but from what I have learned in the past and what people have said here on the forums, it sounds as if you it is probably the MAP or the injectors. And on a side note, what PSI should you get for fuel. I got about 35-40ish which was about the same as my friend with his 94 prix SE.

Yea meltboy i was readin that.  If you have good compression in your motor and your cars doin that, you have to remember that car is 17 years old... old injectors are crap give your motor what it deserves.    On the other hand i found out my problem is completely unrelated to injectors.  Im ripping the front head off tomorrow because cylinder 4 isnt giving me crap for compression!  YAY
