I replaced a starter and oil level sensor, and did an oil change and now it won't start only turns over.

The crankshaft angle sensor is near the starter. Can you check the wiring connection at the sensor please? Here is the location of the sensor so you can check it out. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Hey, Ken, I checked the crankshaft sensor and I found that the plug was in but one of the wires was not even connected. So, I replaced that plug connector and the connector to the oil level sensor and now it starts but it's reading a code p0300 random/multiple cylinder misfire as well as a p0200 injector circuit/open.
