Crank sensor IDK

Hi all


Long story short - 2011 RB Accent sedan issues - check engine light, intermittent start issues, replaced fuel pump, battery, decreased power/acceleration, fuel economy (what’s that?) never had transmission serviced from previous owner - actually I’m damn sure she never serviced it period ....misfiring on 3rd cylinder apparently according to my regular mechanic - fuel gauge won’t give me a clear indicator of range due to the increased usage due to these issues and I’m at my wits’ end....auto elec says CAS won’t show code????

 

The crank sensor won't always show a code for a faulty CPK or CAS
Depends upon the issue and the ECU.

Anyway, do you or can you do any of the maintenance work yourself?
If you can't then that is why your at wits' end.
You bought a used car. And like most used cars, they have been neglected.
You can either sell the car and buy yourself a new one (which has its own issues)
Or you can take this step bu step and try to remedy some of these issues you're having.

Youtube has lots of videos on how to do stuff to fix up your car.
Invest sometime and educate yourself.
It will do wonders for your patience and your wallet.

 

Well it’s all common sense lol - now with autoelec. So let’s see how much $$$ damage comes out of it - worst case is a quick fix and cut the losses...

 

Lets start with a scan and find out what Diagnostic Trouble Codes (DTC) are in the computer.
It will give an idea of what could possible be wrong.
