Fuel pump could be shot. The reason it will run after it has burned all the fuel that has been dumped into it, could possibly be caused by vacuum; as the engine is running the throttle body is actually pulling fuel from the tank, through the fuel line, through the fuel filter and dumping it into the engine. This is BAD, your throttle body was not designed for this. Check your fuel pump. (usually if you turn your key on but don't start the car you can hear the fuel pump prime the engine)

low fuel pressure on the fuel pressure check valve , which is located on the fuel rail that services all the injectors. the car will attempt to start but won't. pouring gasline in the throttle body will start the car but only momentarily..

Could be that the throttle plate (in throttle body) is stuck open. Try to "free up" by sticking a screw driver into throttle body

2 stroke or 4 stroke? If it is a 4 stroke carb model, it has a few accelerator pump. To start you must connect hose prime bulb, pull choke, twist throttle from slow to full throttle 3 times then attempt to start. If you do not twist throttle on the 4 storkes it is hard starting.

You say it runs when gas is poured in the engine but not with the key start. Two questions: (1) where in the engine are you pouring gas, and (2) how are you starting the engine if not with the key? If you mean you are pouring gas in the carburetor or in the spark plug hole and it starts with the key, but doesn't start if you don't pour gas in, the needle valve on the carburetor may be closed or the float may be stuck in the closed positiotion. You might also want to check the throttle linkage.

If you are having issues with it dying, start with cleaning your throttle body and clean or replace you Idler Air Control. That is mounted on the throttle body.

Push in the clutch, set throttle at start turn key ,[like starting a car]

Fill it with gas, pump the throttle 3-4 times, then start normally.

Your 1987 Astro might go full throttle when the engine is started because the throttle is sticking. This could also be a problem with the starter or the ignition hanging during the start.

User Avatar

Its obviously not getting fuel to the throttle body, this is most likely the fuel pump, but you should start by replaceing the fuel filter becase of the low cost.
