Do a 2003 cavalier have a fuelpump reseat button

You need to use a scanner to trouble shoot. It can be a fuelpump relay or fuelpump or a broken timing chain or belt. See if you can find a test port on the fuel injector rail and determine if you have fuel pressure.

Some of the autoparts stores have tool loaner programs. If you can see any rocker arms or internal parts through openings in the valve cover cranking the engine will reveal if the valve train is working or not.

Some cars have ignition relays as well. Autozone.com has free diagrams once you register your car with them.

If you can get into all the gears, like reverse and park, without the button, then you don't need it.

Check in the rear cargo area for a removable side panel. There should be a switch with a button on it. Push the button for 3 seconds and then try to start your vehicle. The switch is a safety switch for impacts and is called an Inertia switch. If you have an Owners manual you can read about it.

If it still does not start, listen for the fuelpump. It should run for 1 or 2 seconds when the Ignition key is first turned. There is a Relay in the Black box usually under the hood on the Drivers side. The Fuelpump relay may be bad or check the fuse panel per the Owners manual.

The chevy cavalier does not have underseat access.Its more foreign vehicles and some newer domestic models that do.

Check in the trunk on the drivers side for an opening in the carpet. There can be 2 switches and 1 is for the Air ride and the other is a fuelpump safety switch. The safety switch is called an "Inertia switch" and it has a push button for Reset. Just hold the button down for 3 seconds and it will reset.

Then turn on the Ignition and you should hear the fuelpump run for a few seconds. It should be ready to start. If the Inertia switch was tripped it is made to kill the fuelpump upon impact. Slamming a door or the trucklid can make it kill the fuelpump.

mostlikely its the fuel sending unit, which is an assembly in the tank with fuelpump. you have to drop gas tank to replace this unit.

bad fuelpump, good luck . just make sure you have spark if so ,then il bet fuelpump is bad, just replace it. it is located inside fuel tank.hope this helps.

Hi the switch should be next to the dimer switch on the dash on the left good luck

check all those item again, especially the crank sensor, check the fuel pump by adding 12v to it, make sure its good. tun on key, make sure your getting 12v from fuel pump wire

Could be a fuel pump relay or fuse. These are both located in the engine compartment fuse box. I would check these both out. If one of those isnt the culprit I will help you push it off the cliff. Thanks for using fixya!
