About ready to pull my hair out.

Long story short I have a 91 GT that I put a s-trim V-1 blower on have it all back toghter and now it will start but will not stay running. I have good fuel pressure, re-flashed maf sensor, good spark, timing is about perfect. I know this is a very generic list of things I have checked but I am looking to see if anyone has ran into this before or if someone can lead me in the right direction of what to check next.
 
disconnect the MAF, take the belt off the blower and see if it runs. If so, then plug the MAF back in and see if it runs. It seems like it takes a bit of tweaking to keep the car running at idle once you put a blower on. Not a lot of experience with them, but a friend has a similar setup.
 
One more bit of info is that when the car does start and die out I will pull the plugs and find them bone dry. Wouldnt after starting the car a few times and it not firing the plugs be soaked? Anyone know what controls the injectors?

Get me a picture of the top of the maf sensor. I need to see what the part number and calibration are.
 
Here is a pic of the maf, sorry about the poor quality. And I guess its a 77 not a 80.

I bet the Maf calibration is wrong. Those unit had horriable issues especially from the time span that unit was recalled right as they were going out of bussiness.Is the sensor housing plastic or aluminium???

If the car starts, then it is firing and the plugs would not be soaked. The hall effect in the distributor is where the signal comes from to fire the injectors. If it is starting and running for a few seconds or so then the sensor is ok. Are you using the stock distributor? Did you try the other things mentioned? The car does not need the MAF, bigger fuel pump or really much else to just idle properly, or idle improperly but at least stay running.
 
I have unplugged the maf and it did not make any differnce. I have not taken the belt off the blower yet. I am using a stock dist with a msd cap and rotor.

Actually in my experence, the problem he is having is exactly what a car with NO MAF will do.....start for just a second then stall....
