First, car was over heating so I changed my thermostat sensor, next I changed the thermostat housing unit. After doing this I found out my water pump was bad. So we go in swap out everything gaskets, grommets, water pump the whole nine yards. Now that the new water pump is in and we bolted everything down made sure everything was grounded the car will crank but will not turn over and start. What should I do next?

Let me make sure that I have this right, you turn the key and the engine spins, but does not actually start, right?

Okay. First thing I would do is check the oil to see if there is any signs of coolant mixing in there. If so, then the cylinder head gaskets are blown, water and oil is mixing, and water got into the cylinders, fouling out spark plugs. Coolant in the oil will look kind of muddy, maybe even like chocolate milk. Hopefully this is not the problem. Let us know.

Ok it's probably not related to the water pump and overheating then. Next thing would be to check for sparks and fuel pressure.

This is a guide to checking sparks from the coil: https://www.2carpros.com/articles/how-to-test-an-ignition-system

If everything checks out there, then you'll want to look at the spark plugs themselves.

--- If you want, you can take pictures of your plugs and I'll look at them and try to judge their condition.

After that, you might want to check fuel pressure: https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

--- You can borrow that fuel pressure gauge from the local AutoZone or Advance Auto store.

Keep us posted.
