2011 hyundai tucson crankshaft position sensor location

I assume you have checked that there is a good 9~10V supply at the ignition coils during crank?

No, I didn't measure anything. It was based on a remote phone call tip, which on my case was even better then a fully qualified engineer's tip, who actually saw the car and could measure it.
Now, maybe you got an idea why I wanted to change it and not from somebody else.

The car has almost 200.000 km, so not bad to change this once.

I have called somebody else, and I made a different deal with him: the car is not starting, so he have an error right?
He told "yes".
and I told I will pay only if you can detect the right cause of the defect, fixing it is another deal, it's ok?
He accepted the challenge.

Others just connect an OBD reader and see ECU no error or slow battery error code and telling me to recharge the battery and whatever else...

I have checked all fuse and all relay in cabin, near engine under steering wheel: all are ok, working.

This guy measured the tension at the main wire for coil the red, and it was missing.
He measured the tension at the fuse at cabin: it was present.

Checked the electric diagram but he couldn't find the "K20" relay location.
Anyway he said the fuses has relay behind and in a VW model if you access it, than it will not work again. Well, it is strange...

So his idea it was to bring the 12V with a new relay and a fuse after the driver turn the contact. That was done in the engine part correctly, nicely, and professional cable usage.
The relay signal it was bad, in 3 location cut the wire to take it, but finally got a good location....well, not so nice, but the problem is solved.
Even the signal wire has an additional fuse, so I could accept the work.

Since he came to my car with his tools and wasted like 3h25m I was surprised with pleasure with the fee. -Versus who actually didn't wanted to get the hands dirty, just take the money. I know this guy will solve my electrical problem, with professional tools and materials, at acceptable price, but maybe he will cut 3-4 or more wire then what is needed for.

I drove the car today. Now it starts stop on cold, warm, not issue at all. I know somewhere I have a wire with a dead relay and +4 other wire +2 fuse +1 relay
