Won't crank as in turn the key but nothing happens or engine turns over but doesn't start?

As in nothing the lights go away when you turn the ignition but it will not crank as in starter does not engage

Also I switch the ignition and starter relays with the fan relays and no change

Voltage gauge reading low? Maybe alternator went?

That's the one I mean, it flashes while you're trying to start it?

Ronaldz

Yes the light flashes when I try to start it but thought the vats wouldn't affect it when it was running and gauge reads 10v

That's a VATS issue if it's flashing when you try to start it. Could the car have died for some other reason while running and then the VATS problem kicked in?

Ronaldz

I don't know it was running just fine all of a sudden it just died

Do you hear the fuel pump prime when you turn the key to "on"?

Sounds like a charging problem, the voltmeter should be reading 13-14 volts when running; or 12 volts with the engine not running.
At 10 volts you have a dead battery.

Try some jumper cables, see if it will start.

If you have another car or a friends car, drop their battery in, see if it starts. If it does, let it keep running and disconnect the negative battery terminal, if the engines dies you have a bad alternator. Get a new one and charge your battery.

Im not saying this is the problem, but the Crank Shaft Position sensor failing or acting up is just about the only thing that will cause an engine to just shut off out of nowhere while you are driving.
But since the starter won't even engage.......I would say its something else.

I done some research found one problem so far I pulled the steering wheel to pull the lock cylinder and found one of the vat signal wires coming broke from the switch will try to repair tomorrow but that still doesn't explain it dieing so I will get that fixed and continue from there and will update post as I go thank you all so far

If your MAP, CMP, OR CKP send different readings to the ECM that don't match up it will shut the door on everything and kill the car. Have you tried clearing any DTC's even if none are showing in between start ups?

Ok here is an update. one of my wires for the switch was broken fixed that problem now it will start but it still will not run there are no DTCS but I am getting a rpm signal in scanner when trying to start still testing things if you all have any advice let me know going to check spark and fuel now then will check sensors thank you all
