Default LT1 runs then dies

I have a 94 LT1 from a camaro that is in a rockcrawler. I rolled the rockcrawler and when I restarted it post roll it was difficult to start and idled rough. I got it home and took apart the intake. I cleaned all of the oil and dirt from all of the sensors. Now when I turn it over it fires instantly but then dies. I can keep it running if I play with the throttle. I have swapped out the IAS, the MAFs, and the TPS.

Note: the motor will run if I disconect the MAF but runs at high idle.

Pls help?

Have you checked the fuel pressure?
