Wally Posted March 9, 2023 Share #1 Posted March 9, 2023 Huh. this is odd. cruising neighborhood. Low on gas. Go to corner store get $5 worth. Head home which is about 2-3 blocks and car dies and wont crank. Definitely a gas issue. Fuel filter is dry with nothing in it. thoughts? even if bad gas would if take hold that quickly Link to comment Share on other sites More sharing options...
SteveJ Posted March 9, 2023 Share #2 Posted March 9, 2023 Try blowing the line out from the front with compressed air. Have someone take off the gas cap and listen for the air coming out. You could have stirred up junk in the tank and clogged the line. 1 Link to comment Share on other sites More sharing options...
Zed Head Posted March 10, 2023 Share #3 Posted March 10, 2023 (edited) "Crank" is what the starter does to the crankshaft. First the engine cranks, then it starts. Are you saying that you have a crank - no start problem? Or a no crank problem? Edit - couldn't see your signature until I signed in. Carbs. Could be water.

Wally Posted March 10, 2023 Author Share #4 Posted March 10, 2023 it wont start. it does crank fine. took off fuel filter, was a clear OEM one so could see it was clogged. Blew compressed air can into line...very faint out of gas cap area. Can is small and weak though. got a new fuel filter and re-tried. Nothing. Checked line and No gas is coming from tank to fuel pump. The fuel pump is was bought new only a year ago so doubt that could be the issue. Will get my big air compressor and blow air back to tank and see if that loosens something up. Link to comment Share on other sites More sharing options...
SteveJ Posted March 10, 2023 Share #5 Posted March 10, 2023 If you have a handheld vacuum pump (like a Mighty Vac), you would put it on the outlet of the fuel filter and try drawing fuel into the filter. If it can, then start to suspect the fuel pump. 1 Link to comment Share on other sites More sharing options...
Wally Posted March 10, 2023 Author Share #6 Posted March 10, 2023 The compressor, surprisingly, blew easily to back. Lots of free air flow. Battery hooked up to charger, tried for a couple minutes to start or at least move some gas up to front. wouldnt start. Took lines around fuel filter off to see if any gas at all was coming up front. Its not. Maybe it is the fuel pump. strange. Link to comment Share on other sites More sharing options...

Zed Head Posted March 10, 2023 Share #8 Posted March 10, 2023 There is a whole long thread about bad new mechanical fuel pumps out there somewhere on the forum. Within the last 5 years I think. Worth finding, it has solutions in it. New does not mean good. 1 Link to comment Share on other sites More sharing options...

Without the spacer the pump can't pump at full capacity as the arm is to close to the rondell on your camshaft! Also the pump can get to hot .. then you will need a new pump.. watch out for the cheap pumps on ebay.. they only last for a short time. (I got the original pump on my 240z now for 50+ years..unbelievable!) Get yourself a new nissan orig. pump if it's damaged. Link to comment Share on other sites More sharing options...

Yes, it would be interesting to hear where @dutchzcarguy has found someone selling discontinued NOS fuel pumps. 1 Link to comment Share on other sites More sharing options...
