I was sitting in traffic on a hot day. The temperature of the engine was getting hot, but not high enough to turn the fan on and then the engine just cut out. I got a tow home and now it will not start. As I was waiting for the tow, the engine did start, but lost oil pressure right away. I checked the oil level and it is full. Now after sitting for a few days, when I initially turn the key, the oil pressure gauge doesn't even move. As I continue to crank over the engine, the gauge starts to go up like I am pumping up a tire and the engine doesn't start. I do have a leak in my water pump that I haven't had before. It looks like it is coming out of the little 1/8 in hole/indentation on the bottom side of the pump. This is the least of my worries, easy to fix. What could be the cause of the engine not starting?
