I have an 2007 Chevy her and my son was driving down the street and the car shut off and now it will not crank .took it to the Chevy dealership and they said it was the starter and fuse block by the engine. So I replaced both the starter brand new and fuse block brand new .and still no start and no crank. All the lights come on but nothing happens. If you can help me please let me know .it all be greatly appreciated . Thanks

Hi Chris, to the forums!!

Engine/transmission/miles may help in the diagnosis.

Is the Check Engine Light on? Has the battery been load tested?

Have the ignition switch related recalls been performed?

Chris Whitaker

No check engine light brand new battery ignition switch has been changed even the shifter has been changed

Alright, then you should start looking at fuses and relays.

Underhood fuse block
fuse #5
fuse #46
relay #34
relay #51

and in the interior fuse block(BCM)
fuse #8
fuse #16

Relays you can swap with a known good relay from a system that is functioning correctly. Insert the relay in the correct orientation, don't rotate it so it 'looks' right.

You took it to the dealer, so did they replace the starter and fuse block, or did you?

I replaced both of them brand new

Welcome to the site, guessing can be expensive, a shame the dealership was just guessing.
Have you inspected , and load tested the battery.
Have you checked for loose , corroded ground connections.
How about the main fuse near the battery?

Did this dealer actually look at the car, or did you ask them what is wrong and they guessed?

Did you check for voltage to the starter? The large red wire goes from the starter to the front lug of the fuse box then directly to the battery.

Any other strange things happening before this?

Well I asked the dealership what's wrong and they said the only thing it could be is the starter and fuse block.so I replaced them. After they charged me 250 bucks for that information. When that didn't work I called them back and they said well it has to be the emc .so I stopped talking to them.because they said it would be 900 dollars to replace it. So I asked how do you know that's it if you didn't check the car again.he said it happens all the time . So i haven't been back there.trying find another dealership .

Oh yes power steering went out right before the car stopped running.so I replaced the fuse my son drove off .and it died. Hasn't started since. I put a jumper on the starter and the engine turned fine .
