Recently my wife was driving our 99 T&C when it suddenly stopped in the middle of traffic on a busy highway, when she tried to restart it there no response, but what she noticed was the oil light would not go out. She checked the oil and it was a little low, the vehicle never started after that, the power is good, it is turning over, lights, horn is good. What can be the problem, can it be a bad oil pump, oil pressure switch, I noticed that the connector to the pressure switch has one wire coming out I don't know if this is correct. Help.

 

Yeah, replace the oil pressure switch and have the ignition module checked. It's probably either or both.

 

I doub't it's the pressure sesensor but I would take it back to the place that did your fuel pump and filter. It might even be something they forgot to plug back in.
