im very confident that everything is tight and hooked up right, the lines still have the factory colour coding on them so i really dont know how i chould mess it up. ive printed out the vaccum diagram and tested all lines for leaks.
when i do get it running its at 4k and im being pulled behind a truck @20mph. but i have to pump the throttle just to keep it running. if it goes under 4k it dies instantly.
i cant believe when i printed the wiring diagram i had the primary and secondary injectors in wrong, but thats all fixed. IM still VERY confident that everything is in working order, remeber this car has NEVER been abused at all all garage keep for years, and only has 40k on it. when it ran it was SMOOTH as silk.

UPDATE!!!
injectors and pressure - Passed
vaccum - Passed
i have to take the the top manafold and try to see if its leaking there, maybe alittle silicon will help but now i cant get it to run under 2k so improvment is great.
more advice is greatly appreciated! thanks again guys and gals!!!

could be excess fuel. i remember when we over jetted this guys carburetor and i mean way over jetted. we pulled the car up to about 30 in second gear before it would fire. it was putting a lot of excess fuel vapors out the exhaust while trying to pull it up to speed. it would only run at a high rpm. the next day we jetted it back to stock and it started up and ran on the first try. after we broke it in for a month we jetted it up 10 on the primaries and 20 on the secondaries and it runs great with the streetport. the stock intake is still too restrictive in my opinion.

oh , yeah about the front hub and front pulley. always keep the hub together with the pullies that it came with. you can not mix and match pullies and hubs. the pullies and hubs are a matched set.

There has got to be an Electricle issue, or a Vacuum issue with that motor.
After all the time spent, I would suggest that you take the UIM/LIM off and inspect everything that is under there.
I would inpsect the Spark plugs, and start making sure that everything was brand new...
Your issue is a stumper

you might be able to make one with a wet/dry vacuum, some dry ice and water, and a home made regulator. 1.) connect the vacuum hose and regulator to the vacuum on the exhaust side. 2.) put the water with the dry in a the vacuum 3.) turn on the vacuum and let the fun begin.
you could actually put a restriction on the intake side of the vacuum too.
you could also rent a party smoke machine but i don't know if this smoke would hurt the car.

Fog Juice Recipe
WARNING: THERE HAS BEEN SOME CONCERN ABOUT THE CORRECT MIXTURE OF MATERIALS TO MAKE FOG JUICE. SINCE FOG JUICE IS READILY AVAILABLE, YOU MIGHT CONSIDER PURCHASING IT FROM A REPUTABLE SOURCE INSTEAD OF MAKING YOUR OWN IF YOU ARE CONCERNED ABOUT THE MIXTURE AND CHEMICALS USED.
WARNING: USING HOMEMADE FOG JUICE IN A COMMERCIAL FOG MACHINE COULD VOID THE WARRANTY.
ALSO: COMMERCIAL FOG JUICE IS FAIRLY INEXPENSIVE ($4 - $6 per quart at Fred Meyers and Walmart) NOW AND HAS BEEN REPORTED TO PRODUCE BETTER FOG.
You can make your own fog juice from glycerin, diethylene glycol, dipropylene glycol, propylene glycol, or triethylene glycol and distilled water. Glycerin is available at drug stores, supercenters, and home-brew stores. The others are available from chemical supply companies.
Glycerine Based Fog
You want to use the lowest ratio of glycerin to water that acheives fog for health reasons. Generally, your fog juice will be between 15% to 30% glycerin and 70% to 85% distilled water. A common lean ratio for light fog is 1 part glycerin to 8 parts distilled water. The lean recipe would then be to mix 4 ounces of glycerin in 1 quart of distilled water or 125 ml of glycerin in 1 liter of distilled water. A common rich ratio for heavy fog is 1 part glycerin to 4 parts distilled water. The rich recipe would then be to mix 8 ounces of glycerin in 1 quart of distilled water or 250 ml of glycerin in 1 liter of distilled water. When vaporized, the vapor should have a somewhat sweet smell. If it smells burnt or fowl, then the ratio of glycerin to water is too high or the temperature of the fog machine is too high.
Materials (English Units)
4 ounces Food Grade or other High Purity Glycerin ($4.00 from drug store)
1 quart (32 ounces) Distilled Water ($0.25 from grocery store)
Materials (Metric Units)
125 milliliters Glycerin
1 liter Distilled Water
Instructions
Mix the glycerin into the distilled water. Stir will. Use twice as much glycerin if you desire thick fog, but some experimentation will be necessary. If you use the leaner glycerin recipe, it will be cheaper, and and the fog will be cleaner though the fog will be lighter and not last as long.

you don't need a fog machine to test for vacuum leaks. Just ears and an air compressor.
Pressure test the intake. Whereever air leaks out fix it until it dosen't. No other method of checking for vacuum leaks works as well as this.
Have you checked/set the TPS to be somewhere near where it should be at?
Are you SURE there are no air leaks in the AFM piping and etc?
Have you managed to get the engine warm yet?
Have you checked the timing since you got it started, have you checked it properly?
it shouldn't just "die" below 2000rpm unless there is a major vacuum leak or other big issue.
