I just changed my coils and wires in my 2007 4.0 mustang and no it doesn’t do anything when I turn the key, just primes Mechanic's Assistant: Can you turn the steering wheel at all? And what about the key? Is it worn or damaged? No the key is fine and no I can’t turn the wheel, it’s locked Mechanic's Assistant: What is the make/model of your '07 car? Mustang Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? Yes by myself, I figured it would be easy enough. I tried checking all the boots to see if they were connected properly which they were. Same as the coils

Howdy from Tennessee, I'm Chris aka Moose. Who am I helping today? I'm glad you've come here to get help. I will do my best to get the answer you are looking for. I help many customers, so sometimes my replies are delayed, I will respond once available. I try to be online at 1-5 pm and 10 pm-5 am every day. - Are you saying you turn the key to the start position and there are no clicking noises, the [starter](/topics-starter-ford/) does not engage, the [engine](/topics-engine-ford/) does not spin (crank)?

Hey moose, I'm Ethan. No there are clicking noises, I can hear the pump and everything turn on. It's just when I try to crank it, it sounds like clicking noises. I just recently changed the coils and the wires and it started doing thatAlso i my radio turns on and off and I'm no longer able to roll up my windows, I'm thinking my battery is dead not sure
Automotive Expert
Hello, Ethan What is the battery voltage with the key in the RUN position? Do you know how to test the inputs to a relay using a volt-ohm meter?

I couldn't answer that question right now as I don't have any tools to determine voltage on either, the car was able to turn on no problem before the DIY job of that helps any
Automotive Expert
Do you know anyone with a voltmeter that would let you borrow it? If not you can buy one, they are only about $30 for a cheap one.

Mm no I don't know anyone but I could possibly get one tomorrow.
Automotive Expert
That would be perfect. A cheap digital tool will do all we should need. Just reply once you have it.

Alright my man, I got the car working and turned on but now I got white smoke coming from my [exhaust](/topics-exhaust-ford/) without any significant temperature rise. Is it most likely a leaking head gasket?The it was at operational temps for a good while and still had smoke coming out
Automotive Expert
If the smoke did not smell bad like it had a lot of fuel in it then yes, it is likely due to it burning [coolant](/topics-coolant-ford/) from a faulty head gasket. A compression test would confirm that or not. Thank you for seeking us for help, I hope I provided what was needed. Press reply if you need to follow up. If you liked my answer please let me know so I can mark your question complete. Moose

The smell of the smoke had a sweet scent but nothing too pungent
Automotive Expert
Coolant does smell sweet

Okay I do have a compression tester so I will check that out, thank you for helping me out
Automotive Expert
You are welcome
