Default new fuel pump and relay... now.. only idles.

So I was wondering if any of you might have any clue as to what I might have done....

Just got done with the TA (yup, another all-nighter) and I fire her up, starts great but as soon as I either 1) put a load on the engine, or 2) give it gas the "Check Gauges" light flickers (1/10th of a second is the longest it's ever on) and the engine sputters, but tries to recover as soon as you take away the throttle, and if not dies.

Only relevant things I did were 1) 255 Fuel pump, w/ HD relay harness (which primes and idles just fine), and 2) Tick Adj. Master(which bled and adjusted fantastically, from what I can tell).

The SES light only came on after I tried to kick the car over to speed density after unplugging the MAF, which the car wouldn't even start then.

Ideas?

Default

Check fuel pressure with car running & see what it does when the engine sputtters. This way you will know if the pump is causing it... otherwise you just are guessing.
