Car Forum / Nissan / Nissan Cars / May 2005I have an 86 stanza wagon 4wd
and an 88 2wd I bought the 4x4 because I had the 2x2 and I thought that I would be able to interchange parts. The guy told me that the only thing keeping it from running was the fuel pump. I took the tank off and removed the fuel pump... tested it w/ a meter and it showed that it "should work" and which contacts on the connector should run the pump... so, I hooked the pump directly to the battery. It worked! Having already looked for the fuel filter, I decided to look better... Found it encased in a box (The best way to describe it)... and took it out... It was clogged to the max... couldn't even blow through it. I decided that THAT was the problem and changed the filter. I reinstalled the fuel pump in the tank and hooked the lines to the pump and then tried to make the pump Pump. no go. The other car was running so I changed the relay from one car to the other. no go. I am a fair backyard mechanic, but I'm stumped! anyine got any Ideas? When you say you "hooked the pump directly to the battery and it worked"... does that mean you pumped some fluid with it?... or just heard the motor running? Professor www.telstar-electronics.com It pumped fluid! It didn't spray, but it was a steady stream > When you say you "hooked the pump directly to the battery and it > worked"... does that mean you pumped some fluid with it?... or just > heard the motor running? > > Professor > www.telstar-electronics.com And now you get no fluid pumping at the fuel rail?

If not, start checking voltages from the pump back to the ignition switch until you find the problem. Also, it may have one of those electro boxes that want to see the alternator turning before it will turn on the pump. My truck does, and it won't turn on the fuel pump until you start cranking the truck.  SignatureScott B. '89 240sx '84 720 KK 4x4 Except when I use connections from the battery, It won't pump. > > And now you get no fluid pumping at the fuel rail? You have tried that > > right?

I put a meter on the different conncections and determined which ran the pump. I put 12v on the two contacts at the plug. It pumped gas. I checked the relay by removing it from the not running car to the running car. It ran. Even though it runs, there's NO exhaust system from the manifold back... and the one I'm trying to get running is a 4 wheel drive... Mostly, I want the fwd to run, because I bought it with money I borrowed from my wife with this dream of getting it going and bla bla bla But! after is all is said and done with the working relay, with the FP in the tank... Lines hooked up... lines not hooked up It won't pump being hooked to the Plug > And now you get no fluid pumping at the fuel rail?
