If it's no fuel then it's probably the fuel pump or the fuel pump relay. If it's restricted or low flow then it could be the pump or the filter.

There's also an outside chance you could have a crimped or blocked fuel line.

SOURCE: Engine will crank but will not turn over

Do this, take the top off the carb, being careful not to damage the gasket. Then take some carb cleaner and clean out the bowl and floats. Remove the needle valve and clean it out. Put it all back together and filling the bowl with carb cleaner. Start it with the starting fluid. Once you run the carb cleaner through it, it should start to run on it's own. Whatever you do don't shut it off for about 20-30 min unless you have to.

Initially I would agree fuel pressure had dropped off after shut down. This fuel filter is a sock screen attached to the fuel inlet tube of the fuel pump and is located inside the fuel tank with the fuel pump. This screen is rarely the cause. You'll need a fuel pump pressure gauge to verify the low fuel pressure at start up. Caution, sometimes this low pressure isn't a faulty pump, sometimes it's a poor wiring connection to the pump motor. An analog amp meter can verify if there is fluctuation/ing current flow to the fuel pump. A fluctuating current flow could mean poor connections, or could mean the pump has/is gone/going bad.

Nobody has messed around with the ignition timing in any way?



If it has stood for a long time(i.e years..) the fuel may have degraded to the point that it\'s useless.



The carbs will smell of fuel, but are you sure that fuel is being pumped to them in sufficient quantity? Try disconnecting a fuel line, crank the engine a few revolutions to see if fuel is pumped out.



Try gravity feeding the carbs. Use a can of fuel connected to the carbs, held above the engine. Get somebody to crank the engine and see if it fires up. If the engine fires up, suspect the fuel pump.. or fuel lines.



An air leak can also cause non-starting. The usual cause is the inlet manifold gasket. Any air leaking through the gasket can cause your non-starting problem. Go back and check that no dirt has been picked up by the gasket before you fitted it/it hasn\'t been ripped. Check that the inlet manifold has been correctly tightened.



It doesn\'t sound as though you have much of a problem .. more of a \'niggle\'.

1981 mitsubishi sigma won't turn off


It was a very common problem on carbureted cars, so common it was given a name: dieseling. You know, as how a diesel engine will run without spark plugs. You shut a hot engine off, there is still a little gas in the intake, and maybe the carburetor still drips a few drops down the throat. The crankshaft is still turning, so gas still gets into the hot combustion chambers, so hot it can still ignite the remaining gas, and you have "dieseling".
To rectify it, manufacturers years ago began putting an electrical solenoid in the carb's main fuel passage to stop fuel flow as soon as engine is shut off. They called this a fuel cut solenoid, fuel shut off solenoid, idle stop solenoid, or an anti-dieseling solenoid. I know datsuns had this solenoid at least as far back as the early '70's. Works very simply: turn the key on and solenoid was energized, retracting a plunger pin in the fuel passage. Turn key off and solenoid gets no power, so a spring inside the solenoid pushed the plunger back into the fuel passage. It almost entirely eliminated the problem, as long as the carburetor was adjusted correctly.
Actually, I think your '81 should or might have this fuel cut solenoid on the carburetor, and if so it may be inoperative and needs replacing. Not very expensive, and easy to replace- just screws out. Some had only a single wire connector, and some had two wires to them. It would probably be the only electrical to the carb, other than any electrical going to an electric choke, if so equipped.
Happy motoring with the old mits, Sarah. I still have an old Datsun pick-up, and now an '87 Sentra, carbureted unfortunately, lol.

Why do I have to pump the gas pedal to get my 1991 Nissan stanza to start


You probably have a carburetor that feeds fuel to the engine rater than Fuel Injection. Fuel Injection squirts a bit of fuel into the ignition chamber when you turn your key, allowing the car to start, with a carburetor, you have to manually pump the fuel into the ignition chamber to start the engine. Usually Two to Three times should be enough.

2003 Nissan Altima won't start?


A car needs 3 things to start. Air, fuel, and spark. Check that it can get air by removing the air cleaner and inspecting it. Leave the air cleaner off for now. Try a squirt of starting fluid into the carburetor (not a lot mind you, just a quick squirt). Be prepared to quench a flame if the engine backfires through the carburetor (have a wet towel handy). Crank the engine. If it fires, you have spark. If it does not fire, you have ignition problems. If it fires and stalls out quickly, you have fuel problems.
For fuel problems: Be sure you have gas! (I know it is obvious, but check the tank!). If the car has not been used for awhile, the gas may have gummed up the carburetor. While it is possible for the weekend mechanic to take a carburetor apart and clean it, it is probably best left to a professional mechanic. Verify that you are getting gas to the carburetor by detaching the rubber gasoline hose at the carburetor. Most cars today have electric fuel pumps, so turning on the ignition should result in a stream of fuel from the gasoline hose. If not, crank the engine and see if a mechanical fuel pump moves the gas. If you get no gas, find out why or your car will never start. If you get gas, the carb is probably gummed up. It is best to conduct this last test into a mason jar to catch the gas, and it is best to postpone the cigarette break until after the test is complete.
If you suspect the ignition, pull a spark plug. It should look clean and whitish to light coffee color. If it is filled with carbon and oil, you have other engine problems. You can look for an ignition spark by laying the plug case against the engine while it is attached to the distributor wire. Crank the engine and you should see a spark jump the gap at the spark plug tip. This spark is often small and hard to see in sunlight. Do not perform the spark plug test in the temporal vicinity of the fuel test. A hot spark with gasoline nearby is dangerous.

A car that turns over means that at least the battery is good. Try next to insure it has air, gas, and spark.

I have a 92chevy cavalier when the motor gets hot the car cuts off .when u let it sit for 30min. It will crank up an go help me what is wrong


Hot starting problems are usually fuel related. When a hot engine is shut off, the temperature of the engine and everything on it continues to rise for awhile as the engine undergoes a period of "heat soak." This can cause fuel to boil inside the carburetor bowl, fuel lines and fuel filter. When you attempt to restart the engine, "vapor lock" obstructs the flow of fuel and the engine doesn't want to start.
This is much less of a problem on fuel injected engines because the fuel is usually under much higher pressure inside the injectors and fuel line. Even so, a fuel line routed near an exhaust manifold or a fuel rail that's exposed to a lot of heat may still suffer the same kind of problems.
Heat soak problems such as these can sometimes be cured by wrapping insulation around affected fuel lines, and/or installing an insulating spacer or heat shield under the carburetor.
A Seasonal Problem
Hard hard starting tends to be a seasonal problem, but may be worse in the early months of spring when refiners are switching fuel blends. Gasoline refiners produce fuel with a slightly lower volatility rating (called "Reed vapor pressure") during hot summer months because lower volatility fuel is less likely to boil and cause hot starting problems. During the winter, they switch to a higher volatility fuel because it makes cold starting easier. But if you still have "winter" grade fuel in your tank when warm spring weather arrives, you may experience some hot starting problems. The problem will go away, however, as soon as the refiners in your area switch to their summer grade fuel

1988 F-250 460 engine stalls when dribing down the road


On older, carbureted engines, cold stalling (and hard starting) is most often due to an automatic choke that is sticking, misadjusted or broken. Cleaning the choke mechanism with aerosol carburetor cleaner may free up the choke allowing it to work properly again. If the choke housing as an electrical heating element, the element may not be receiving voltage when the key is on, or the element may have burned out (check resistance with an ohmmeter).

Other causes of stalling with a carburetor include an idle speed adjustment screw that is set too low (turn screw to increase idle speed rpm). The engine may stall if the idle fuel mixture screw(s) are not adjusted correctly or the idle mixture port(s) are dirty or clogged with fuel varnish deposits (clean the carburetor and readjust the idle mixture screws for smoothest idle). Stalling can also occur is there are vacuum leaks in the carburetor, under the carburetor (bad base gasket), or any vacuum hose connections to the carburetor or intake manifold
