I wasn't having any trouble with the van until I took it for oil change. After change, when I stopped at stop sign, it said "low oil pressure". And van stopped.I got it started and took it back and the station checked it, called a dealer and said they didn't know what it was, it wasn't the oil change. It started, I drove it a few blocks and it stopped and said "low oil pressure". I parked it. Later took it five miles, it stopped on me and wouldn't restart. I had it towed home.
A "mechanic" came out, put in two spark plugs, an air filter and put it on charger for six hours. He came back, took charger, didn't talk to me. My mom called him and he said when he took charger off, it started. When I tried to start it it didn't start, it says no oil pressure. (I guess that is because it wouldn't start so that wouldn't have showed up.

In the past, I have changed oil filters on these and trapped the wire harness for the oil pressure switch in the filter causing this issue. Have another shop check this for you to verify.

Have the computer scanned for code/s-who knows could be the fuel pump and oil pressure sending unit acting up-

She took it into a mechanic and he said the motor was blown. He said most likely from no oil. My daug. Contacted the station who did the oil change and where she had taken it back to after noting the low oil pressure and them telling her "the oil pressure was fine." And the station said "well, we are not mechanics". So it will have to be junked as the mechanics she talked to said it would cost up to 2000.00 for new motor or more. I had also told them about checking to see if they had trapped the harness and they said "no, it was fine that he had checked it when she brought it back the first time".I doubt if he did if he "wasn't a mechanic. Thank you for your answers.
