I remember when I first replaced fuel filter I was also surprised how long did I have to crank the engine before it started.

Should I just replace the >pump all together (is it bad?) or did I severly mess something up. Thanks >for any info. Well, if it stalls, apparently something needs to be fixed. Did it act like this before you changed the check valve? If not, then you messed something up. But it rather sounds like a problem associated with cold start valve or warm-up regulator. Is your pump noisy? Those pumps usually begin to make lot of noise long before they fail. If your car stalls only when cold and otherwise runs good, I wouldn't blame the pump, but you may have your dealer test it with pressure gauges to make sure it is OK. Good luck! Alex
