no fuel pressure
ok guys, lemme tell ya what i got first....89 f350 four door dually. 460 that i built for it. police interceptor heads, roller rockers, ford motorsport cam, msd dist, box, coil. tossed the efi, went with a edelbrock performer rpm intake and 750 cfm carb. got a adjustable 3 port maloory fuel pressure regulator for it and i replaced the inline fuel pump with a holley red pump. now the truck used to run like a beast. now, i have no fuel pressure. now what is weird about it is that i can hear each of the in tank pumps spinning, and i can hear the holley spinning too. but the fuel pressure gauge next to the carb says 0. none. zilch. does not like to run. i'm gonna start by disconnecting the line in front of the regualor and after it to see what kind of pressure i have on each side of it. then im gonna go before and after the holley pump. anybody else have any good ideas? this truck is fast becoming a big time PITA. thanks

no fuel pressure
well, i had just put a new filter on it after it started havin no pressure, and that didnt fix it. i pulled the line before the in frame pump, turned the key on, fuel shot out. repeated after the in frame pump, same thing. went up before the regulator, same, put it all back together, fuel pressure was back. put new spark plugs in it and it runs. kinda confusing but at least it runs now
thanks for the input though
