95 doge ram fuel pressure issue

Question for you all... I've got a 95 Dodge Ram 1500 V8, believe it's a 5.2 liter.. It idles fine, but when driving it studders while accelerating... seems to happen at all speeds and any rpms. The spark plugs/wires, dist. cap and roter, fuel and air filter have been replaced. Relieved fuel pressure, hooked up a fuel pressure guage to the test port. turned key to on position.. very minimal pressure (supposed to read 31-33psi with regulator, with regulator hose unhooked



39-41psi). Tried starting the engine. Would turn over but not start. Waited.. psi never really reached high enough. Unhooked the hose connected to the regulator and it started up immediately. Went to
40psi. Plugged regulator hose back in and the gauge stayed at 40 (didn't shut off in between). Now it won't seem to start with the regulator hose plugged in. Does this prove that the regulator is bad? The local Discount Auto wants $180 for the fuel pressure regulator.. does this sound right? don't want to buy it if it isn't it. Thanks a lot for any suggestions or insight you guys may have!!!!!

Maybe it isn't a RAM.. it is a van. The rest of the specs are correct thought. Thanks

fuel pressure on that should be 50 psi take a clear conmtainer such as a 2 litre clear pop bottle and attach a hose to the test valve then insert the other end into the bottle at bottom and start vehicle it should fill the bottle with no air bubbles after the first 10 seconds or so. if there is air bubbles after 30 seconds the pump is bad be careful no arching plug wires!handling gas like that can be very dangerous but it's the onlty way to find out

k... so the regulator probably wouldn't have anything to do with that? the only reason i said 40, is it is what the book said.. hmm.. the pressure guage has a release valve with a hose.. will try that. regardless if the engine is on or not the psi from initial key on should put the psi past 15 right? thanks so much for an answer tim.. much appreciated!
