Hyundai Intermitent Stalling 

@nadinesmits362 glad you find it useful

Did it work?

@@GicaPhp we haven’t replaced it yet. I spoke to a mechanic and he said it could be the fuel pump since it’s not throwing a code (no check engine light). I’m going to keep an eye on it.

@Rhodyman13 just watch the rpm counter if goes up when cranking

​@@Rhodyman13I think that's the toughest to diagnose. I have that issue. No lights just will stall out at lights sometimes now. Started happening at the end of the summer. I thought it was a fuel pump going bye-bye.. I wish then I could just take it in and have it diagnosed and replaced lol

@@GicaPhpif it goes up while cranking it’s the sensor?

Glad it helped

I hope it helped

@@TTV_Tonioo it looks like wiring issue

it can. what fault codes you have and what symptoms?

@@GicaPhp I have no fault codes (There is no check engine light when it happens) On a completely random basis my car simply struggles start. It just cranks and cranks but won't fire up. Eventually, (at least so far) it will finally start and then it will usually go another week & multiple times where it starts up just fine. And then out of the blue it will happen again, where it struggles to start. And now recently (twice now) it has stalled at stop lights for no reason and struggles to start after. All of this with no check engine light.

@@TheoriginalChuckJ when that happens just see if your rpm gauge goes up to 250rpm when cranking, if it doesn't you need to check your crank sensor. An oscilloscope would be best on both cam and crank sensors

Thanks for your follow up. It is much appreciated. Unfortunately, I never thought to check the RPMs during the difficult starts. I will check from now on if the issue continues. However, earlier today I bit the bullet and had my Cam shaft position sensor replaced. I had to try something. I have started the car twice since then with no problem but I will need several more starts to know if it solved the issue. I will let you know if it does. Thanks again...

@@GicaPhp Well, I had the Cam shaft position sensor replaced last week and I was hoping that this would solve my intermittent difficult starting issue and random stalling issue. But, on my drive home from work today my car stalled again at a red light. And once again it required extra cranking to restart. After it finally started and I continued driving I noticed that my RPM gauge wasn't working at all. It was reading 0 RPM while I continued my drive home.

You are very welcome

any fault codes?

@@GicaPhp P2187 ( system too lean at idle Bank 1) that code I get

@@GicaPhp P2187 system too lean at idle bank 1.Is the code I get

@@sibusisomemela2739 check for split intake manifold, cracked hoses, exhaust manifold air leak before o2 sensor

@@GicaPhp Will do , thank you

make sure your battery is in god condition

I had this problem too. Turns out there was a short circuit in the alternator. It was fixed
