Hi, i have a 2016 zforce 800 ex, ay the beginning It shut off running, one then It became More often. I replace muy Fuel pump AND Fuel filter, this because It was clogged. But after that It still shutting off. It vibrate a little bit on ralenti. It doesnt throq any codes. AND when i remove the spark plugs they are black.  Any one that have the same issue Is i?

Never had that happen but black plugs usually means either very rich or using oil. Sense you said the filter was plugged, some trash may gave gotten through that fine, high quality CFM fuel filter and is making the injectors leak...badly enough to make it die and run rough. Pull them and just turn the key on while they are still on the rail (fuel supply). If they leak, replace them.

Thanks for the support, i try that AND no no leaks, what i see, it seems to shut off the injectors. What i do, Is turn on the car, AND want until It shut off, then i remove the injectors from the housing AND see if the injector Is opening, i see that Is not opening(no gasoline going out), after several tries the car turn on with one cylinder, i see gasoline out of the injector hahaha

Might be a crank sensor ? That doesnt detecta engine rotation AND shut off ignition?

Hi just for AND update, It was an o2 sensor bank 1, because i live in México Is almost imposible to find a dealer near, so i bought AND change mine with a walkerproducts 350-34076, just cut off AND Solder the plug from oks o2 sensor.  You need to know the color table. Thanks!
