J30 cut-off while driving,,,,Tried everything

[kennywildgoose]

1st I noticed a louder then usual noise (tapping valves), I added some oil & additive to quiet the valves, that didnt work, after driving for about 25min. I heard a howling/wheeping noise I thought one of my windows was open,but not th case, the noise went away, I slow down to about 30-40mph but the noise came on and off within 3-4 mins. then BLANK the engine stop running, I put the car in neutral and let it stroll to a safe place off the highway, let it sit for awhile then try to start it, the engine turns over strong but wont start up, the car has been sitting since then, a machanic friend came to check some stuff: Battery is good,,getting fuel to the rail,, starter is fine, STILL NOT START,,please help

Welcome to NICO!!!

Best place to start is to pull codes from the ECU. It will pinpoint what's wrong, save time and take away any guessing.
