  Q: What are some troubleshooting steps for a starter motor that does not turn at all?

  A: It is important to ensure that the vehicle's shifter is in neutral or park (automatic) or the clutch is depressed (standard) if the starterdoes not turn at all after the ignition switch has been operated. Make sure that the battery has sufficient charge and that both battery and Starter Solenoid terminals have tight cables. If the engine fails to crank while the starter spins, it probably means that there is a slipping overrunning clutch within the starter. This necessitates removing this apparatus from its place of attachment, for then only will it be possible to replace it. In case when you press on the key but the starter does not work while solenoid gives a click sound, there are three causes of these problems which lie either in battery, main solenoid contacts or ignition switch itself. Caution: before inspecting start problems ensure that battery is fully charged. When activating switch does not create any sound of plunger moving up then something must be wrong with the solenoid itself or circuit is opened. Connect a jumper lead between positive terminal of battery (+) and "S" for checking solenoid operation. It means that if after this test, starter runs properly, one can conclusively say solenoid is ok otherwise; there must be other issues like wiring or neutral start switch or even a problem with ignition switch itself. When this happens take out the whole assembly so as to do thorough inspection using appropriate methods and repair where necessary. First check whether your battery has power and all its connectors are tight in case you hear your engine cranking but very slowly. If oil viscosity differs from what is recommended by manufacturer, cranking would also be slow especially if some parts have already seized hence requiring immediate action taken against them even without dismantling an engine's cylinder block componene.If this normal operating temperature runs up, shut off vehicle's engine; detach coil wire from distributor cap and ground it to any part of the engine. With negative lead connected to earth, positive lead is attached to terminal coming out from the starter on solenoid. When an instant reading displays, go ahead with cranking operation under which you will record volts from a voltmeter. Do not run your starter for over 15 seconds at any given time. For instance, if the speed of cranking is normal and ammeter shows 9volts or more , such readings would be considered normal in this case so one should not worry or think about replacing parts.What will show that your engine starter is damaged while its reading is above nine volts? If the non-stop turning of this device results in a low ammeter readout say below 9 volts, then solenoid contacts have likely burned out.

  Q: How to remove and install a starter motor for Chevrolet Astro?

  A: Disconnect the cable from the negative terminal of the battery. Raise the vehicle and support it securely on jackstands. Working under the vehicle, remove any starter braces or shields, if used. Label the electrical wires and then disconnect them from the Starter Solenoid. Remove the 2 starter bolts and slowly lower the starter from the engine, noting the locations of any shims, if used. Shims are used on some engines to establish the correct clearance between the starter pinion and the flywheel/driveplate starter ring gear. Installation is the reverse of removal. Be sure to install the shims (if any) that were noted during removal. Tighten the starter mounting bolts securely. If the starter whines during or after engine starting, shimming may be necessary. Disconnect the cable from the negative equipped with an anti-theft audio system, disable the anti-theft feature before performing any operation that requires disconnecting the battery or disrupting power to the stereo. Raise the vehicle and support it securely on jackstands. Remove the bellhousing lower cover. Inspect the flywheel or driveplate for signs of unusual wear such as chipped or missing gear teeth. Using a wire type feeler gauge (round diameter), measure the clearance between the top of the flywheel/driveplate ring gear tooth and the bottom of the starter pinion tooth. Use a screwdriver to manually engage the starter pinion with the ring gear. The clearance should be between 0.01 to 0.06 inches. If the clearance is less than 0.02 inch and the starter whined after engagement, the starter is too close to the ring gear and must be shimmed to increase the clearance. If the clearance is greater than 0.06 inches and the starter whines during engagement, the starter is too far away from the ring gear and a shim(s) must be removed. Remove a shim, tighten the starter and measure the clearance again. To install a shim, loosen the inner starter mounting bolt (the one closest to the engine), remove the outer bolt and then slide the shim between the starter and the engine without removing the starter.
