Thanks for choosing FixYa and welcome to the site. Have you checked for fuel and spark? The car needs air, fuel and fire to start. Since it is cranking, it is either fuel or fire. We need to test them both.

    You want to make sure the fuel pump is kicking on when you turn the key. You should hear it when you first turn the key. You want to check your fuel pump fuse/relay also. You could have a clog in the fuel filter. You want to make sure fuel is getting through the fuel filter. Check your fuel lines and see if you can see fuel at the fuel injectors. You could test the fuel pressure to make sure it is correct. You could refer to your manual for the correct measurements. If the fuel checks out, you need to test for spark at the plugs.

    OK. That rules out fuel. You need to test for spark. You need to take out your number one spark plug tube. You need to get a screw driver and place the metal end into the tube. You can lay it on the intake but make sure the screw driver is firmly in the tube. Place it on the intake or anything metal. Try to start the car. You should see a bright blue spark come from the plug tube. If you see the spark, you have fire. If you don't, that is the issue. If you have a spark plug tester, use it. If not, do it this way and let me know what you see.

    If you are getting spark, you need to make sure it is not your timing belt. It may be something electrical. If you are not, it could be several different things, such as plugs, wires, distributor, dist.cap, coil pack, rotor, cam or crank sensor. You will need a voltage meter to test any electrical wires to parts.

The location of the fuel pump cut off switch on a 2005 Chevy Cobalt ?

There isn't one.
What testing have you done?
Make sure battery has a full charge. If it cranks good but won't start, have a helper crank it while you visually check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. If your missing everything check for rpm signal. Any applicable trouble codes?
When you first turn on the key, no crank, can you hear the fuel pump run for a couple seconds? There is a fuel pump fuse in underhood fuse box.

How to fix 2007 chevy cobalt with error code p0202

DTC P0202:Fuel Injector #2 Control Circuit .You could have an open in the wiring or in the fuel injector coil windings ! Check for voltage at the pink wire . The other wire comes from the PCM , a transistor inside the pcm turns the injector on an off by grounding the circuit . You can test this by hooking up a test light to battery positive an the other pointy end touch to a T pin probed into that terminal at the PCM . With engine cranking the test light should flash . You should also ohm check injector coil ! the resistance of each fuel injector should be 11-14 ohms.

My 2007 Chevy Cobalt engine light blinks and the motor starts to miss. But the OBD code reader says there is a link error. I changed the spark plugs but it's still missing from time to time. What can I do?

Could be a bad coil but usually blinking is emission related, catalytic converter? Recommend you take that to a certified Chevy mechanic for a diagnostic, it's not that expensive.

My 2007 Chevy Cobalt will not crank, and will not start. I try to start it and absolutely nothing happens. What is this, and how do I fix it?

check for fuel pressure or listen for fuel pump operation in fuel tank when you turn ignition switch to on position for ten seconds. if no could have faulty fuel pump fuse or relay pump could have failed.if yes hear fuel pump running could have plugged fuel filter. if fuel system okay problem could be ignition system.have vechicle code scan look for fault codes.could have faulty ignition module faulty camshaft sensor or crankshaft position sensor.faulty PCM.

2007 chevy cobalt I went through water wont start

You're hydrolocked. Pull the sparkplugs out and crank the engine for 30-60 secs. there is a VERY GOOD CHANCE you could have done some major internal damage. Be prepared to replace your engine, but this might work.

Won't start or crank after wreck.

this is probably a safety. no explosion, shut down. check to make sure no wires were cut/damaged and look in the trunk for an emergency shut off. there might also be a shut down relay onboard. if there is it's under the hood in the relay box.
