[QUOTE="doctordick, post: 174100, member: 2595"] Colt, you didn't say what kind of pump you're running, but if you're running off the original relay and wiring, the pump should run for about 2 seconds when you turn the key on. If the pump is producing adequate pressure, that should be enough time to pressurize the system. Draining back is not really an issue because fuel is retained in the throttle body, it just needs to be pressurized. Check out the rest of this thread for some troubleshooting tips. If there was a lot of gunk in your filter, your pump may be damaged and not producing enough pressure. Be sure to check your MAP sensor, and look for vacuum leaks. Either one can cause similar symptoms I've thought about it but never tried running a Holley blue pump, I'm just not sure if the pulsation of such a high volume pump would cause a problem :dunno: Stock intank pump is the best I've found.
