Will not start

Hi and thanks for using 2CarPros. Com.

Since you were working on the engine, the first thing I need you to do is confirm the crankshaft position sensor is still connected. I have attached three different pictures. Each shows a possible location for your engine. Since you are getting fuel but no spark, this is my first suspect. The last two pictures show what the sensor looks like and it is most likely location (below the starter).

Note: If you have a live data scanner, check to see if there is an RPM/crank signal. If there is not my guess is the sensor is unplugged.

Let me know if this helps or if you have other questions.

Take care,
Joe

Hi and welcome back.

It is possible to get a bad thermostat. However, when the engine is hot, are all the coolant hoses hot too?

If you want to check the thermostat, remove it from the vehicle. Boil water and drop the thermostat into the boiling water. You should see it open. If it does not open or open fully, it is bad.

Also, a bad radiator cap can cause an engine to overheat. The boiling point of coolant, water increases when its under pressure. Check that too.

Chances are you do not need this, but here are the directions for replacing the thermostat just in case. The pictures attached correlate with these directions.

Please keep in mind, a bad head gasket, plugged catalytic converter, and other things can cause the engine to over heat. Here are links for testing both the converter and the head gasket.
