Welcome to Fixya!

If the engine cranks over normally when you attempt to start you car, but the engine does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION. The engine needs adequate fuel pressure, a properly timed spark and normal compression to start.
TIP: To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. IF it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.

TIP: Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.

TIP: Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine.

Thank you for using Fixya!

I replace a new starter on 2008 Saturn suv 2.4 4 cylinder still doesn't crank

Sounds like a security system issue. Using the key fob to lock and unlock the doors will usually reset the system. You may have to do this procedure a couple of times and see if it works

I have a 610 mule it won't start with the key.but will start if you jump the starter. Any idea?

It has a transistor that boosts spark power for starting when the key is in the crank position. usuall when it fails the engine will start but die when the key returns to run. Other times fails to start but will run in run position.

Could be the key switch. You would need to check the coil for battery power with the key in the on position.

I have a 2000 Dodge Dakota Quad cab SLT 4x4 that won't start. The engine will turn over but, as soon as I release the key, it shuts off. The ABS and BRAKE dash lights stay on.

It could be a cam or crank sensor. Have someone plug a OBD II reader in and pull all the codes.
That will give you some idea.
Please let me know what you find.
