Yeah this is all without the INT-X. but as far as it idleing, it should be able to do that wihtout the INT-x with no problem. i also cleaned off the e shaft sensor before re installing. I can nake a tester to the other parts and test and see if they check out ok. I will also try cleaning the MAF.
So you think i should throw the INT-X back in and give it a shot with it in. In my opinoin a low RPM like that its not goin to make much of a difference. But hey, what do i know.
and... i cant give it a good drive, it wont idle so no stoppin. or pushin the clutch in and lettin the rpms fall down to idle.
should i try the holding it at 3k rpm. seems kind ahigh for just sittin there lol.. wont the car get pretty hot also.
When i try to crank it with the starter, it still gets nothing. Does not even sound like its trying to fire just a really fast rotation of the motor but its not stumbleing like its hittin on any.

Hopefully you find out the solution to what is wrong with your engine. Have you done compression test?

No compression test, figured new motor would have compression. Did you have to push start it or did your start off the starter? also, did you have to keep the rpm's up for awhile before it would idle after it being started?

You should do a compression test. I think the guy who build your engine won't forget to install the apex seals in your engine. But I would do compression test first to get it out of the way and narrow down on list of issues why engine won't start.
I never done push start on mine. My car will start fine on its own but it takes long crank to get it starts. The crank map is better now and it will start on the first try on a long crank start. In the past it flood first after the first try and then I have to pull the fuse and then it will start normally.
My car starts off the starter. I don't have to put my foot on the gas pedal to keep it idle. I do, however, have to floored the pedal while starting sometimes to get it to start. It will idle on its own around 1200 rpm at the beginning and then settle down to around 800-900 rpm after about a min or so. Have you check if your starter is hooked up correctly? Or is it still in good condition?

Hum how old is this fuel for the hard to / non start issue at hand? If this is gasoline more than 4-5 months old... might want to siphon out and put fresh super.

Starter works perfectly, It turns the car over pretty fast actually. I was rather impressed lol. Tonight i will get the INT-x back on the car and check all my sensors and clean the MAF. If still no start i will get it pull started and try to take it out on the highway and back to get it some action and see if that helps.

There was the original gas in the car from a year ago when i installed the motor. I syphoned almot all of it out except maybe..... on 1/8 tank or less. then put in fresh 91 by the gas can. i now have a total of a bit over a half tank of gas.

I think your engine just so new and it acting up. Try to get the thing start and drive around in an area where you can do continuous driving without stopping. The thing may just need to be run in. Could there is air bubbles in your gas line?

Na, its ran long enough now that any air in the line woudl be out. I agree with the driving it thing. The one time it did idle, it sounded really smooth and good. Like a rebuild engine should lol. I may try to give it a good drive tonight down the highway for a few miles and back. Might have a helper car follow incase i need a pull start lol.

You will most likely have starting issues for the first 3-400 miles depending on what was replaced in the rebuild.
You can let the car run at 3k for as long as you want just put a box fan in front of it.
This is a new engine its going to do lots of weird stuff. Long starts are normal.
You need to crank that thing until it starts if it doesn't start after 10 seconds of crank stop wait 5 mins and try it again.
One more thing to check have a friend crank the engine while you look at the eshaft pulley. See if its wobbling.
This is not a dirty sensor or dirty maf problem. This is a new engine break-in issue.
If all of this does not work your last option is to clean all the grounds and put dilectric grease on them.
Good Luck, Shady out.

Thats my plan... pull start it then get it out for a short drive... after that if it will idle i will let it idle for awhile... if it wont, i will try to keep the rpm at 3k.

Will it run at 3-4K for long enough to get it warmed up?
If you flooded it with the big injectors in Sec position ( 2.5x fuel) it may take a bit of a run to get it cleaned out enough to idle well
It is difficult to get much to happen with more than one variable being off at a time
The intake is a big problem in this car...poor MAF readings and it runs like crap

yeah it runs smoothly when your keep it at an rpm. sounds perfect... it just wont stay there by itself. it ran for about 10 min last night at around 2k. if i stay in the car and keep it at 3 k it will run for as long as i want to most likely... its sounding more and morelike i should pop start it take it for a drive hten have it sit at 3k for a bit.

Yup everything is the same as the pic is. . . . as far as logging the MAF at idle... if i can even get it to idle.. i will. but that has only been able to happen once so far.

OK, another update for ya. got home and installed the Microtech again. took out the car and pop started it. got it back to my driveway and sit in the car playing with the throttle for 30 minutes straight. I helt it at 2k help it at 3k reved it from 2 ta 5k as i was told by steve kan. everything that you could do with the throttle i did. when you would hold it at a constant rpm and hold your foot still it would be really really smooth... then after a minute or so it would start missing .. and jumping a little in the rpm. Reved fine every time you give it gas and when it was not missing it you had excellent throttle / rpm controll.
After 30 min of throttle play it was time to see if it would idle. I slowly backed off the throttle closer and closer to the rpm it should idle at. when it got to that rpm....... it died. NO restart.
everything checked out good on the gauges. temp sat at a constat 145ish... and its 92 degrees out now. oil pressure looked good along with air fuel. it was mainly in the twelves but when it started missing, it would go lean and hit the 15,s and 16,s which is as high as my gauge goes.
any more info or does it jsut need another thirty minute round ?

never checked the pully... totatty spaced it off. will do when i get a helping hand.
when this first started i pulled one plug wire and got spark.... thats all i checked. I need to check them all. will do also when i get a helping hand.
since i posted last i pull started again. this time it stumbled a little at idle like it wanted to but still died

some possibles :
vac leak
low compression due to seals needing to bed in
int X idle maps no good
irregular airflow on the maf (when using stock ecu)
combination of 2 or more of the above
BTW - you did check that the temp sensor was plugged in ?
