Hi

I think it could be the crankshaft position sensor, not quite the typical symptoms, but it could be.

Best Regards

Ok where would that be on this car I'm alittle stupid but thank you, do you think it's just that or could it be something else?
(If it helps the last time it started it was slow then it fired up after turning 4times then it stoped new plugs and everything i just don't want to bring it in and drop alot more for something I could kinda do my self)

If the car not crank, or key doesn't unlock/lock,,

i think; it signs of:-

bad battery or ECU went away..!!

Thank you but the key never was able to unlock/lock it but yes is the a ecu test I could do and would a c class work as a parts car but thank you I'll test battery 🕶️

Could be good to check battery and its terminals and connection to ground.

Otherwise without codes, try logical approach. Do the car have fuel pressure i.e. fuel pump wprking okey? Fresh fuel? Sparks? As engine turned we know key and computers accept the key and code.

Key works brand new battery and starter still just a click but not from starter, sounds like it's coming from mas, need crankshaft position sensor also but still nothing everything is good just won't crank like the starter isn't getting anything but the starter positive does spark when touched so maybe bad ground? Or locked motor because it clicks once then won't do anything on 3rd position untell you go to 2ed then 3rd again then the click but nothing

CPS goes bad when engine is hot...cools and then will restart

bad fuel has nothing to do that it won't crank

I would go with a bad/low battery or bad ground wire

Austin Mahala

okay thank you I just put it in battery and so it's probably a bad ground but would you say it's the background on the starter or the battery itself is everything Powers up and it always hooks up perfectly fine just to start it won't turn over won't even click so it could be a bad ground on the starter I can check that out I thank you for helping you guys if you guys can think of anything else please feel free to let me know

Austin Mahala

it was the starter but now it's smoking bad but thank you guys for your help☺️
