MAPed Blue Top Swap, NOT staying running! Please Help?!

If the car starts and runs, then fuel is definitely getting into the rail.
The question that needs to be answered, is how much fuel ?? Dying
when you hit the throttle can indicate that there is only a dribble of fuel
getting in. At idle or revving without load, the amount of fuel required
by the injectors is very small. But when you stomp the throttle, the ECU
calls for a big squirt of fuel, which because of low flow/pressure, the
injectors cannot deliver. I'd guess that it just goes so lean the mixture
cannot be fired, and the engine dies.

Pull the FPR off the rail and crank it. If there is not a heap of fuel squirting
out from the rail, you have a blockage.

Pull the pulsation damper off the rail, take out the bolt from the banjo,
and crank it (or just get the pump to power up). If there is fuel squirting
out of the hose, the blockage is at the damper.

Fuel comes out of the banjo and goes up the outside of the bolt,
lifts the diaphragm, and then goes down the inside of the bolt to the rail.
