SD to MAF conversion

well I sold a guy a computer to do a speed density to MAF swap on his 88 Tbird (already has the HO swap), at any rate, This thing is about to drive me crazy and I want it out of my yard/driveway!

He got the IST http://www.mass-air.com/Products.htm mass air conversion and we followed directions to the TEE, Now car will not start and STAY running, it will turn over and "start", then just shut off. Double/triple/quadruple checked wiring and no dice yet...IST's "tech" support while answering quite quickly was no help..

Fuel pressure is LOW (imo) at around 24lbs as measured on the rail with a gauge.

You can get it to stay "running" (and I use that term loosely) by feathering the throttle but there is no decent idle and it certainly won't run on it's own.

The computer came out of my fairmont (a9p) and is known to be good...

and ideas or things to check that maybe I haven't thought of would be GREATLY appreciated!!!! I'd be willing to give a "reward" for proper tech support too.....
