What would cause this?

Hey guys,

So I have been randomly having issues with my Jeep not starting after I have driven it for about 15-20 mins. It has happened to me 2 other times prior to today. I don't drive my Jeep very far just because I am slowly doing work to it to ensure that it is running well and reliable.

I did the Team Rush mod, and it seemed to be running well. The last 4 days I have been running up into the hills to do some Turkey Hunting and everything has been fine.

But today I went up (took me about 15 mins to get to my spot) and I headed into the woods. As I was stopping to call it did it to me again. When I went to start my Jeep...it would crank but it would never ignite. I believe it may have flooded as I could smell a strong smell of fuel.

It has a new battery (replaced last year) and has new plugs, wires, rotor dist cap and coil.

I have MUCH more hunting to do but I don't want to be stranded..I want to solve this so I can trust and take me Jeep out more.

Thanks guys

Just a bump before I go to sleep.

To clarify and/or shorten it up a bit. The Jeep with turn over and crank but it will never ignite and run. It does this after it has been running for 20 minutes or so....otherwise it seems to run and start fine. It also doesn't always do this.

Thanks again for all the help and information, this board is a life saver

If it is carburated and not fuel injected, it sounds like the float level may be set to high for inclines, thus causing fuel to come out of the fuel bowl vent on an incline and flooding out the motor. The strong smell of fuel is an indicator of this. When it has a hard time starting the next time, push the gas pedal wide open, to allow more air in the carb to lean the fuel mixture, and see if it starts.

I am not familiar with the mod change you spoke of, but that may have caused a higher fuel level in the carb.(If it is carb and not fuel injection) If it has Fuel Injection, you may have a bad mass air sensor, O2 sensor, or TPS switch causing the fuel mixture to run too rich. But if your issue happens on inclines, that tells me it is more than likely a carb.
Weak spark can cause a rich fuel mixture too. Check all connections in the ignition system, especially ground wires for good ground. A continuity tester can check ground wires for you.

^ interesting point, wonder if its flooding out from a stuck float. My first thought was coil but thats already new.

Thank you guys for the suggestions. It does have a carb and yes the coil is new. Not sure if there is an easy answer or way to tell me how to adjust the float if that is the problem?

You should be able to locate information online on adjusting the float level in your carb. You could also be getting some dirt particals in the fuel system tht may be causing a needle and seat to not properly seat, thus causing the engine to sputter or start to load up like it is flooding out.
