Hey guys, had a really weird issue today and trying to figure out what might cause it and if all those issues are connected!
So i had my slip and vdc lights come on in a middle of the drive and RPM gauge stopped working, showing 0 all the time, than i pulled to the shoulder and tried to turn of the car and turn it back on, well it didnt work.
The car was cranking and was refusing to turn on, eventually from xx number try it finally started! I was able to make it back home, while still having those lights and non working RMP gauge on! Every time i turn off the car it will only start from like 5th try and will still have those lights and non working TECH on. I checked the battery and it wasnt an issue, no CEL lights either, im in panic!!! It is clearly some sensor i assume but why there is no code? or maby im so unlucky that my starter went bad, brakes went bad(we get those lights when brakes are bad) and tech went bad all at the same time, that would be really weird, and hard to believe!! What are your guys thoughts, please let me know!

Sounds a lot like a crank position sensor.

 

Thanks for your input, i thought the same thing, but why check engine did come on? and how is rpm gauge related to all of that

 

The tach gets it's signal from the crank sensor which is why I suspect the CKP. Sometimes sensors fail in ways that DONT throw a diagnostic trouble code, still need to troubleshoot the system but I would start at the CKP since it's notorious for causing no-start conditions AND it's how the engine measures rotation speed for the tachometer.
