99 jeep Cherokee inline 6 137,000 miles. car stopped running all of a sudden going down the highway. still has power. will turn over fine but won't start. has fuel pressure in the fuel rail, replaced the whole throttle body assembly and still did not start. please help me.
Check spark to plugs. Possible crankshaft position sensor. Located at rear of engine between engine and trans.
I had exactly the same thing happen to me and it was merely the IAC module had popped up and was not securely in place. The IAC (intake air control) is located behind the air inlet on top of the intake manifold. I clicked it back in place and it started an ran just fine. The way I determined what was causing it was by renting the diagnostic tool from Auto Zone for $160 and it gave me four possible causes. I started with the IAC module because I had recently had it replaced. Hope this helps. The four possible causes by the way were dirty throttle body, vacuum line leak, faulty IAC module, and poor electrical connection to IAC. Hope this helps. Mine is also a 99 Jeep Cherokee.

What have you checked as far as spark goes? Spark plugs, wires, dist. cap, rotor button?
if you dont have any spark ten you probably need to change your ignition module or coil pack,but i would also check your fuses because you could just have a blown fuse
