Hi well I was on the highway cruising about 70mph when the low oil pressure then all of a sudden it shows engine off and just shuts down. I let it cool down I know I had oil as I did a oil change a week ago. But I checked anyways and I let it cool down and it ail not start up jus a click and smoke from the starter. My mechanic is telling me my started is blown and can't do anything if it won't start. My question is what could be the problem? I had used the search option and nothings showing. Could it just be a switch or could the oil pump be gone?
