Question about 2000 Chevrolet Astro
It's full of fuel and will turn over but it won't start
You need to have 4 things for gas engine. , 1. compression, 2. Gas or fuel, 3, spark, 4. air. to find out here is the fastest way to test. Remove a spark plug wire from spark plug put a screw driver into the boot of the wire and put it 1/4 inch away from a good metal ground with another person cranking the engine over see if there is blue spark, yes? then go to next test get a can of starting fluid and spray a 2 second burst into the intake while cranking the engine, does it try to start? if yes you have a fuel problem, things to check replace fuel filter, remove fuel tank and check fuel pump and fuel sock depending on year, if it's a mechanic pump you will need to test it to see if the check valve is bad or a blown diaphragm. next put your hand over the intake manifold and crank the engine does it have vacuum? yes? then most likely you have compression, if not then you may have broken a timing belt to know for sure does it crank over fast? if so you will need to replace a timing belt. If you need more help you will have to supply us with make year and engine size to help you.

You could have a fuel pump, or spark issue. You need to know what is missing first!!! Fuel or spark.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they get loud or stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.
If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.
