Car wont turn over had the starter checked and tried a new battery fuses we checked were fine when you turn the key on the gages work radio etc...just wont turn over any ideas?

Battery cables ! Do you know what voltage drop testing is ? Starter Voltage Drop

Are you saying when you turn the key to start the radio and dome light go off ? That should be normal unless the draw from the starter is too high. The start position only powers the relay-solenoid under the hood.
Do you have full battery power at the starter when the key is in the start position ? Battery cables clean and tight on both ends ?

That sounds like battery--wiring-or starter. Check the battery voltage. It should be 12.6. volts with engine off. Clean the battery terminals.

I would have the battery checked out still, it don't take much power for the radio to work, and by what you say, that the gas and temp. gauge jump up and down when trying to start, that tells me weak battery,most auto parts will do a free battery test for you,have it checked out. hope this was very helpful.

CHECK THE INSTRUMENT CLUSTER FOR POWER TO GAUGES TO SEE IF THEY WORK WHILE IGNITION IS IN THE ON POSITION.IF NO CHECK THE 40 AMP IGNITION FUSE.IF FUSE GOOD IGNITION SWITCH IS BAD OR HAS A LOOSE OR BROKEN WIRE.IF FUSE GOOD ALL GAUGES IS WORKING.I BE LOOKING AT STARTER AND STARTER SOLENOID.REMOVE THEM HAVE AUTO ZONE TEST STARTER.OR YOU CAN GET A REMOTE STARTER SWITCH AND SET OF BATTERY CABLES.HOOK BATTERY CABLES TO A BATTERY.WITH STARTER OUT OF CAR TAKE BATTERY CABLES HOOK NEGATIVE BATTERY TO STARTER BODY FOR GOOD GROUND.TAKE POSITIVE BATTERY CABLE HOOK TO STARTER POSITIVE TERMINAL WHERE POSITIVE BATTERY CABLE GOES.THEN HOOK THE REMOTE SWITCH RED WIRE TO STARTER POSITIVE TERMINAL AND THE OTHER REMOTE SWITCH WIRE TO THE S OR SWITCH TERMINAL ON STARTER SOLENOID.PRESS THE REMOTE SWITCH IS STARTER RUNS GOOD WITH NO FUNNY NOISES ITS GOOD IF STARTER DONT RUN THE STARTER SOLENOID OR STARTER IS BAD. THE PROBLEMS IN YOUR CAR COULD BE A BAD KEY TRY ANOTHER KEY YOUR CAR HAS THE THEFT DETERRENT MODULE SYSTEM BEST TO HAVE CAR SCAN TO CHECK THE THEFT SECURITY MODULE AND THE TRANSMISSION NEUTRAL SAFETY SWITCH IF ITS BAD STARTER WONT WORK.ALSO CHECK THE THEFT DETERRENT MODULE RELAY. BEFORE REMOVING BATTERY CABLES TURN OFF RADIO SO YOU WONT LOSE YOUR RADIO PLAYING CODE.

You will have to check, at the starter, for power to the SMALL wire on the starter solenoid (which is on the starter) when turning the ignition switch to start.
If there is power to this wire ( usually purple ) and power at the LARGE cable ( from the battery ) at the starter end.....you need a starter.

If you do not have power at the small wire at the solenoid with the key in start position and battery power is OK.....check the safety neutral switch.Moving the shifter around a little can sometimes allow the car to start if the neutral switch is worn.

A new battery does not always mean a fully charged battery.
Try a boost from another car before testing the starter for power.

The battery cables need to be clean and tight....and check the ground to the engine as well.

Everything else may work OK with bad connections,they don't use the power the starter needs to turn the engine over.

check battery voltage it should be 12.5 volts.if all is good .you have a bad starter or starter solenoid switch.i

Hi
Try to jump start the car.
Put the jump leads on and leave it for 10 mins
that will charge the battery up
then try and start.
Also check the starter motor.

try the solenoid for the starter.

check fuses under the hood the main fuse may be blown are the crank fuse
