I know I'm jumping into this a bit late, but have you checked your regulator to make sure that is not the problem?

You will probably want to check the pressure with the vacuum line disconnected just for the hell of it to see what it is. Also while you're at it, you can check the vacuum line itself to see if it is wet inside and smells like fuel. Or fuel may even be coming out of it (BTW, don't be a dumbass and point it at you're face or anything.)

Or it could be your pump like you said. But if it's running like **** and you're seeing a pressure issue on a gauge on the schrader valve, then you mught as well check the easy / cheap parts first.

Sounds like it's right where it should be. And if nothing is coming out of the vacuum line then the diaphram isn't ruptured. That doesn't mean that the regulator is good... but chances are it is just fine.

Nothing is coming out of the line. Its like engine has a hard time keeping up a low RPMs. When i crank it revs then almost dies out, bounces once or twice then evens out. Same thing when i put on A/C. Sometimes it doesn't even out when cranking or putting on A/C and dies out. Its not running like it used to, seems i'm lacking power and its just not as smooth as it was a while back.
I am at a loss at this point. Its been doing this for a while but the other day when going down the road rpm's shot down to zero and car died. Cranked it back did it again about three times within a mile and that was a first time thing.

I can't get it to run right. I crank it and it dies. I crank it and give steady gas and it dies. But does maintain fuel pressure it seems. Bout to call a mechanic or something this is tickin me off.
