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.

SOURCE: 87 nissan starts then stalls

jdmbaker: There are a few areas I would suggest looking in.
First, I would be looking for a false air problem. This is a condition where you have un-metered air getting into the engine. A torn airflow meter boot, or large vacuum leak such as a split pcv hose.
Second, your injector pulse width is primarily dependent on the coolant temperature sensor. This component is located at the front of the motor just below the thermostat housing. The sensor gives the ECM resistance values based on the temperature of the coolant. If the sensor fails, usually, they have a tendency to create a lean condition. This shortens the pulse width of the injectors which essentially starves the engine for fuel. One way you can perform a quick test for a lean condition, is to pinch off the return hose for the fuel going to the tank. If you look at the fuel hoses, they run right next to each other. You have one which comes from the fuel filter. That is the feed line. Pinch the other hose. This will boost the fuel pressure causing more fuel to be sprayed out of the injectors.With the hose pinched, hit the throttle, if the engine will rev up, you persue the lean condition theory.
Third. Check for a weak spark. A severely worn cap and rotor or bad plug wires can cause a hesitation and stalling problem if they are bad enough.
Fourth. The air flow meter could be faulty. This is a very common symptom matching you description.
Odds are that one of these are the solution. Good luck and let me know how you do.

When you remove the fuel tank on a 1991 nissan stanza, the cap you have to undo to get to the fuel pump, what is the technical name for that piece so that i can find a replacement part for it?


I believe u are referring to the lock ring. U should use a brass drift (chisel) and tap it on the raised edges of the lock ring to remove it. U can also use a narrow wood block. The point of course, is to not use metal on metal, which may cause a spark when u strike it, and any gas vapors may ignite (brass won't spark).
