Starter not working

When this happens, have a helper turn the key to the start position while you check for voltage to the starter's smaller wire. You should be getting 12+ volts. Let me know what you find.

Please run down this guide and report back.

Here is the wiring diagram that you are going to have to follow to test the circuit.

Pick your symptom below:

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

Compression:
If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing
belt/chain.

No crank at all/nothing/nada:

Could be the starter, starter relay, clutch switch/park and neutral switch and ignition switch assuming the battery and connections are good.

It's sparking because the starter is shorting or wires are hitting someplace they shouldn't be. You may have a bad battery as well. Get them both checked

Either the battery is drained or the security system is triggerre and not allowing you to crank. Try a jump start to see if it works.

The security system is triggerred. Try closing all doors and using the key to lock unlock and retest.

Check the battery terminals. Try cleaning and retightening them.

No crank at all/nothing/nada:

Could be the starter, starter relay, clutch switch/park and neutral switch and ignition switch assuming the battery and connections are good.

So is the battery dead or what?
Maybe you need a new one?

You said battery is good and it is dead? No indicators etc when switch turned on?

You need to provide us with as much information as possible because we are working blind and you are our eyes.
