Question about 1992 Chevrolet Astro Extended
1992 chevy astro died while driving. It would restart with hesitation, and now it won't start. Turning the ignition will cause the starter to make the ussuall sound of trying to crank over the engine, with no luck. fuel pump? other engine parts linked between ignition and the engine turning over? Thank you very much for your response. Dean
I'm assuming you have a 4.3 liter? First, you need to know what is missing, spark or fuel when it won't start. When it gets to the no start mode, that is when you need to put a spark tester on one of your wires and have someone crank it over while you watch for spark. If it's throttle body injection, look down the body (Where the carb is) to see if you have a fuel spray while cranking. It is a little hard to see. Also used here is a noid light to see if your injectors are getting the "spray" signal to turn on. You see that some tools are needed. If it's injected, every cylinder has it's own injector, and you can only use a noid light. To see fuel here, you hook up a pressure guage to the schrader port on the fuel rail. See if you have a fuel pump sound when you first turn on the key.
Spark could also be a module or hall effect switch in your distributor.
This is why you need to see what is missing, or goes away first.

Fuel pump is a good place to start
