Fuel Pressure Regulator

A couple of weeks ago I got a 86 300zx(t). While trying to start it and being unsuccessful, I noticed my FPR is missing the connector...completely. I have no idea where the wire would be that goes to the FPR. So question 1, from the FPR, where does the wire go to/ come from? I need to know so it can work and question 2, if I get one of those Ebay FPR, can i use it on this car or no? Thanx for helping me out

The other end of your temp sensor wire should be connected to your ECU. I think it's basically for hot starts.
You need to be more specific about the ebay FPR. If it's adjustable and boost referenced, it's probably a waste of money unless you have the performance modifications to need it.

Which temp wire are you referring to? I didnt know the aftermarket FPR was adjustable. The reason im thinking of getting one is because I dont even know if the stock one is working or not.

Your FTS wire. Isn't that what we were talking about? The stock FPR is working if your car runs. But...if your car doesn't run that doesn't mean your FPR is bad. A lack of signal from your FTS will not keep your car from running.
Post a link to that ebay FPR if you want to talk about that.

The Ebay FPR is just an idea at the moment. What I need to know where does the wire that plugs into the FPR come from. Im not quite good with fuel systems yet but I figure this car isnt going to run until I get power to the FPR.

The FPR doesn't have power. It has vacuum reference. The vac line go to the FPR solenoid. That does have power. The fuel temperature sensor (FTS) is screwed into the FPR. That is what the wire is for.
