Wrangler died and won't crank back up....please help!

I just got a 97 wangler with a 4 banger and 5 speed tranny. I got it home and as I was going up my drive way it stalled and wouldn't crank back up. I turned the key to the on position to see if I could hear the fuel pump and didn't. So I took intake off sprayed starter fluid in it still nothing. I was told by a friend to check the crank position sensor, took it off it looked fine. I wiped it clean and put it back on. Still nothing. The jeep turns over like its gonna crank but it never does. It doesn't turn over slow or anything either. What should I try? Also I noticed that my gauges don't move when I turn the key to the on position. Should the fuel and volt gauge move? Could it be the computer? Thanks for any help

Btw....... I know I can do the key thing to check the check engine code but my check engine light isn't lighting up. I even tried a brand new bulb and still didn't light up. so I have no way to get the check engine code

Have you checked all your fuses and relays? If the crank sensor fails it won't look any different then it did from day one! The only two ways to know are to run codes if engine light is on, or replace it.

Some codes will be stored even without the CEL being on. Turn the ignition key on-off-on (not to Start) three times within five seconds and then leave the key in the on position. Wait several seconds, have patience, any stored codes will show up in the odometer. You will know if you did it right if you at least see the usual '55' code show up that just means no more codes follow.

Not to mention you can't tell a bad crankshaft position sensor by just looking at it.

Check your battery connections for lose or corroded connections. It sounds like you have no battery power.

Edit: just saw that you said it cranks but doesn't start. I figured since your gauges aren't moving and the dash doesn't light up it didn't have power.

Would a bad crankshaft sensor cause the fuel pump not to come on? I guess I should change that first and see what happens

And like I said before, I can't see what the check engine code is. The light will not light up at all. The bulb is not blown I put a new one in it already. I already know that the light blinks when you check for the code, but it won't blink if the light is not lighting up at all.

They charge a deposit, but they give it back upon return!

The CEL doesn't need to light up for the above method of displaying any stored diagnostic codes to work.

Ok...got a scanner from autozone. It wouldn't work because I guess there is no power to the obd2 connector. Guy at autozone asked if my power outlet was working so I tried my phone charger and it wasn't. So I guess I need take dash apart and see if there is a wire disconnected or something.

Check all your fuses, behind the glove compartment and inside the power distribution center inside the engine compartment on the passenger-side fenderwell, in front of the battery.
