Hello and welcome! My name is ***** ***** I can assist you with your question. Does the check engine light come on with the key on? Do you hear the fuel pump prime when turning the key on and cranking?

Customer: replied 7 months ago.
No engine light on and I yes on the fuel pump
Expert:  Amedee replied 7 months ago.

Ok, what size engine do you have? Does the ignition coil have power while cranking?

Customer: replied 7 months ago.
It's a 4.0 and idk about the ignition coil
Expert:  Amedee replied 7 months ago.

Ok, the most common cause of a no spark condition on this vehicle is a bad camshaft position sensor, crankshaft position sensors and or bad ignition coil.

Customer: replied 7 months ago.
none of them 3 will throw a code, cause I had it scanned and nothing came up and I've replaced the crankshaft position sensor not long ago
Expert:  Amedee replied 7 months ago.

They may or may not flag a code in the computer. It all depends on how they go bad. YES, it is possible that they could go bad preventing the wengine from starting and not even set a code. That is why it is important to run some tests/checks before replacing any of them. Again, I would start by checking for power at the ignition coil while cranking the engine over.
