THanks again for the help. Those are all good ideas, I think since I havae the pump offf, I will start there and see if it pumps water hooked up to a 12 volt batt. I wont be able to test it till this weekend though.

Thanks for the reply. No im not sure its the fuel supply, although, I did turn the car over with the fuel line unplugged and it would not pump any fuel through the line. Any sort of weird vacume issues it could be or is the fact that fuel is not squirting out of the hose while engine is being turned over a give away that its a fuel delivery problem? I want to be certain it is though before I spend the 120 on a new one. Is there anyway to test the fuel pump since I already have it out? Such as hooking it up to voltage to see if it turns on ? Also, do you know where the fuel filter and inlet screen is so I can check them? Thanks again for the help.

Hey everyone. I have a 1980 Datson 280ZX that wont start. It was running great untill one day I went out to start it and just fired up for about 3 or so seconds and then died.. If I let it sit for a few minutes and then try again, it will do the same thing--start for a few seconds then die. So I am thinking two possble problems, either fuel pump or the relay switch. I would have just assumed the pump was the problem, but I have done some reseach and this relay switch keeps coming up in the search results, so I thought Id ask someone who knows. Any other possible problems I am leaving out? I have tested with a test light and verified that there is voltage (when the key is turned on) going to the wires plugging into the fuel pump, so its not electrical- but does that also rule out the relay? I currently have the electric fuel pump removed..anything I can inspect on it to help diagnose the problem? Also, can these fuel pumps be rebuild for cheaper than buying a nwe one. Where could I find one for the lowest price? Thanks in advance for the help Justin
