jeep doesn't turn on now

My jeep doesn't turn on. One day I was driving it on the road and it turned off on the road and didn't start. Starter works, jeep cranks up but doesn't start. I checked the fuel and fuel squirts out the fuel valve when the key is on. I checked the code flashes on the dash and it is 36 and 24. I know what 24 is throttle position sensor but I don't know what airswitch solenoid circuit is . Would bad throttle position sensor cause my jeep not to turn on. And does any one know what a code 36 airswitch solenoid circuit is and does. thanks

Use starter fluid to determine whether it's spark or fuel.

My bet is fuel and the pump is to blame.
Check pressure at the schrader.

When my pump started failing last week, it threw TP24 error codes.

My jeep had a new fuel pump installed about 2 to 3 years ago so i don't think its the fuel pump. And I give it gas and it still doesn't want to turn on.

ok i checked the fuel rail to check out the if the fuel pump is bad with the key in on position and at first a little gas came out but then after a second no gas came out. Does a good fuel pump suppose to squirt gas non stop through the underhood gas valve or does it squirt a little and stop.

Try shooting some starting fluid into the intake while trying to start it. If it stays running then it's fuel and most likely the pump. That's where I would start. Just because the pump is a few years old doesn't mean that's not the issue. I went through two pumps in four years. But those were bad luck I hope.

I think most of us can all agree on Jeeps, zombies, bacon, beer, and big boobies.

It's supposed to squirt non stop and strong. I know, mine did the same thing a while back. Check the fuel pump and filter.
