No start on Laredo 3.7

is there anything I can check before having to replace the fuel pump? I did have a code pop up involving the oil pressure sensor, is that related at all?

Have someone test the fuel pressure, I think it should be at 50 psi. The fuel pump is inside the tank so it is no fun to replace

So just to recap, is the engine actually turning over?
Reading your posts it sounds like the engine stopped and hasn't turned over since??
If so it sounds like the engine has locked up I'm afraid.

Try spraying starter fluid again while cranking it and if it’s cranking the engine or starting then shutting off then it’s definitely a fuel related issue.

Ok so I finally said F it, and took it to my mechanic, and 3 weeks later he tells me it’s a blown head gasket… so I guess that’s it for my Jeep?

I think the culture tries to teach us to dump a vehicle when any engine or transmission issues pop up, because it is “more than the vehicle is worth.” But $1500 to fix a head gasket is still much less than a car loan to buy a different vehicle. Consider repairing the head gasket and driving your Jeep for many more years.

Ya know what, I agree. I love this car more then any car I’ve ever had, and with 2 kids it’s perfect for my family.

Always a good idea

So reading through the thread, a 2nd opinion is never bad options. That said if they have visually seen a head gasket leak, such as coolant in the combustion chamber, that can be shown using a boroscope. Another method is cylinder pressure test, and or a compression test. If they have shown you that, it's cut and dry. A head gasket is a pretty reasonable failure if you had a rad leak. When system pressure drops in a cooling system, the engine can now get much hotter than it normally should.

These are pretty head gaskets to replace. Worth replacing in my opinion, assuming the body is in good condition.
