ok so here is ther story of no fuel to the carb. It all started a few weeks ago on my friends 85 gs. it was having probmels starting. then one day it just wouldn't start. so i went over and looked at it. first thing i tought was plugs or just flooded. so i took out the plugs, and turned it over a without them in. put them in and still wouldn't start. so i diconected the fuel line from the carb. no fuel came out when we turned the engine over. put in a new fuel pump still nothing. new pressure regulater nothing. bypassed the fuel cut off thingy still nothing. dropped the fuel tank to check out all the tubing from the tank on. i could blow through every tube as long as it wasn't connected to the fuel pump. so i was looking at the black dragon book and saw the idle stop solenoid. i went ahead had ordered one for her. im not even sure if this is the problem but it's the only thing on the fuel system that isn't new. so i have gone through all the stuff on the FSM that i downloaded and i can't find it anywhere in there. does any one know where it's located? and have any insight as to what the problem could be?

1) Make sure the tank's got gas in it :p
2) Usually you can hear the fuel pump running in these things, but use a voltmeter to check the wires going to the fuel pump to make sure it's getting juice. You don't have to be cranking the engine, just have the key to "on" and there should be voltage. If there isn't, there's the problem. Look at the fuses, if they're good, check to see if the wire's cut/broken anywhere. Ask someone else for the next step if you're not getting power - I hate tracing down electrical issues so I'd run my own fused/relayed wire from the battery at that point, but it's not really the proper way to do things. You might want to jump to the fuses before climbing under the car and testing with a voltmeter - up to you.
3) Assuming the pump is getting voltage, and assuming the new pump works... I'd disconnect the line right after the pump. Gas should be spilling out with the key off. Once you turn the key on, gas should be spraying out (or at least spilling out really really fast). You might want to have a bucket under the car to catch the gas.
4) If all the above 3 things actually checked out, it's gotta be a blockage in the line between the pump and the carb. An air compressor can usually take care of it - just make sure you've disconnected the line from both the carb side and the pump side. Check after for leaks too - if the blockage is due to the line rusting out the compressor can make a new hole in the line (although if there's a pile of rust in the line you probably want to consider replacing it anyway).

Good luck!

fuses are good did that. i got a brand new fuel pump so that shouldong be the peoblem. but i will take the voltmeter over there tomrrow/today. and see it what's the prob. i know the lines aren't blocked like i said i could blow through all of them.............. but any idea where this "idle stop solenoid" is at

i would say bad ignitor .It had problems starting and then no start. ignitor triggers voltage to fuel pump on 85 model

Stock fb fuel pump is turned on by a relay on the side of the steering column, under the dash. Most 1st gen RX-7s have had this relay removed and 12v wired to come on whenever the ignition is turned on. No fuel pressure regulator on 12A cars, so I don't know what you replaced besides the fuel pump. You didn't mention the fuel filter, but I assume you replaced it already. Never heard of an idle stop solenoid. They must be talking about what Mazda calls the richer solenoid. Not likely that it will solve your problem. First thing to do is connect a volt meter to the fuel pump terminals and check for 12v.
