Symtoms of bad fuel pump?
Ok car runs unbelievibly good for about 15-20 minutes after running. then it just runs like crap. i can hear my fuel pump make a lower whine (like its not spinning as fast). could my pump be going?

FWIW...I've dealt with FP suspected problems that have required a pressure monitoring test of .5-4 hours...Mustangs, Fords, gm's, mopar's and ricers...some passed the test and the problem was id'ed elsewhere in the system (ignition module, coil(s), exhaust backpressure, pick-up coil, crankshaft position sensor, MAF sensor, VAF sensor, ECM), others failed and the FP had to be replaced.....need to get the data ....or......replace it and hope......next in line would be the MAF and the ECM.

i got my back seats and sound dampening out, so i can hear it pretty good. how should i go about checking the fuel pressure? do i buy a gauge or what?

if your pump is singing pretty loud its probably going bad

well do i need a line or will the gauge just thread to the schreder vavle? or should i just buy a gauge and mount it by the hood, so i can see it all the time?

It has been my experience that fuel pumps go bad and stay bad. I wouldn't think it would get better after it sets a little. Before you waste more cash on this problem, i would bring it in and get it hooked up to the computer. Might be somthing simple you have over looked

i replaced the filter about a month ago.... i noticed my problem comes up more when it is hot out. ill let it sit overnight, then it will run like a raped ape for 20 minutes, then it starts stuttering, and it gets so bad i eventually cant even drive anymore. it feel like its bucking when i floor it. just feels like a lack of fuel. once i hit 2nd gear, it gets a bit better and smooths out. if anyone has ANY thoughts, please help!

Check your fuel filter... My car would run great for a few minutes, once the dirt would get clogged in the fuel filter it would run like ****, it's worth a shot...
