fuel issues

[sno_boarder4343]

Ok so i have the engine in the car, it is an all stock 4g63 just rebuilt for a 1990 laser rs, and now i am trying to get it started up but i have been having troubles. first off it seems as though maybe only two or three of the cylinders are firing and i think it may just be because the other one is not getting fuel. it kind of sputters in cycles like its not fully started up or something. however at one point today it seemed as though it was running fine but when it was running i had no control over how much gas it was getting or anything like that. it sounded lke it was trying to die but if i put my foot all the way down and have the throttle body all the way open it will sit at like 1000 rpms and sputter there (though i think my tac is off because it sounds a lot higher than that). but then after a little while it shot up to what it claimed to be 2000 rpms but i wasnt controling that because my foot was off the gas pedal. of course that was just before my oil pan gasket blew out what could be the cause of this problem? am i just not getting gas up there or is it something else? one other thing my book is not real clear on which solinoid is which with my fuel pressure and evaporitive emission purge solinoid so which is which? and could that be the cause of my problem?
here are some pictures

That is the federal emissions setup you got there. The one on the left is the purge control solenoid and the one on the right is the fuel pressure control solenoid. To me it sounds like your ecu is going bad or you have a crap load of shaving in your oil pan like I did.

Your getting fuel so them solenoids are not your problem. Make shure your getting spark to all the cylenders. to eliminate the spark problem. If you still not getting her to run then it might be a bad injector. Take a multi meter and make shure the injector is 2-3ohms. You might also have a dead spot on your ISC.

To test you ISC and make shure all the values of each are at 28-33ohms.

TOP OF THE CONNECTOR
1 2 3
4 5 6

Test all of these sequences
1&2
2&3
4&5
5&6

If any of them are showing no connection or well above the range of 28-33ohms then the ISC is bad.
One very common way for the ISC to go bad is for running rich.

I noticed on my 90 Talon Tsi that the vacuum line going to the back of the fuel pressure solenoid, is broke off at the plastic nipple.
So, what exactly does it do?
I plan on buying a new one to replace it any way, I was just curious.
