fuel sys pressurization




I replaced my check valve on my fuel pump and noticed after when
I put everything back together and tripped the fuel pump (so's it can
pressurize the system) it took awhile, is this normal? How long does
it take for the fuel system to pressurize after the intake line has drained
out? I let the pump stay on for a bit and then tried to start the car, it
took about 12 times until it turned over. One thing I did notice the car
now starts up rather quickly on warm-starts, however still hesitates
on a coldstart, and after it starts it runs at about 1000 rpm's for a few
seconds and the drops below 500 and stalls. Should I just replace the
pump all together (is it bad?) or did I severly mess something up. Thanks
for any info.
