Default Fuel pressure

Ok so when i turn my car to the on position i hear the fuel pump turn on but i also hear my abs box screw up. It sounds like there are two quarters fliping around in it for two seconds. and it causes my fuel pressure to screw up while it does it. So i hear the constant pressure build up then it studders while the abs messes up then its ok again. Well yesterday i had a half tank and my car shut off like the fuel pump was dead. I had to let cool for an hour before i could drive it home. Is there any way the abs box could screw up my fuel pump. Or do i just need to replace both

You should have 41-47 PSI with the key on.

Yea, assuming something is wrong with out any numbers to back it up, is a silly claim. Pull of the vacuum line and turn the key with the Fuel Pressure gauge connected and let us know. Should be 43 w/o the line on.
