Car wont turn over Options

[block]

My dads 99 celica gt wont start. Itll try to turn over but theres something preventing it from turning over completely. Possible fuel issue? He did a tune up but nothing. No clicks and no, its not the battery. Anyone have an idea? Ill probably go back and get a video tomorrow after work. Never dealt with this before. It has always been alternator, starter, or battery for me. Thanks.

You said no clicking, but the engine's trying to turn over.

If you mean you can hear the starter spinning, but not the engine, that would indicate the starter's not engaging against the flywheel properly, which says the teeth on the flywheel or the starter gear are broken.

If you mean the engine's not actually turning over then I'd agree with Box and Richee, you're looking at the starter motor or the connections to it. Until the starter can spin the engine, fuel and spark aren't a factor. You stated the battery was tested for sufficient voltage. So check that your clutch start switch (manual transmission) or neutral start switch (automatic) are working. Then get the starter tested and check continuity (manual transmission has a starter relay and resistance on the primary connections to it.

If you mean the engine cranks too slowly to catch and fire, that's usually a weak battery or connections. The ground strap near the starter's key for this one. It could be a faulty starter, but Toyota starters rarely fail except when their solenoid contacts wear out, which is a $10 fix.

However, if you mean the starter motor is cranking the engine but the engine won't keep turning without the starter -- it's not firing -- that's a different set of issues. Fuel and spark are the question.
