no start!?

i just pulled my airbag off my steering wheel to make sure the plug was still in becase my light would come on then if i hit the horn would go out... So anyways, i put it back on and tried starting the jeep.... no start, just cranking. I just drove 300 mile yesterday and drove around today this afternoon and now it wont start? Could my fuel pump relay have quit, or what should I start checking? any help would be great, its my dd

what should I be hearing? when it cranks it doesnt sound like its getting fuel... i can tell that much. Can you usually hear the pump prime? never took notice. i checked all of the fuses and they are good, pulled them all and checked with a meeter.

also, to hear it prime is a growl when you first turn the key to on. Errrrrrrnt. Turn it to on and hold it there for a second and listen. As soon as it gets to "on" you should hear the pump.

I think something is wacky in the column by the symptoms. ...my opinion anyways based on what your sayin'.

While you wait to hear the pump listen for the relay clicking if it clicks fast then it primes then that could be the computer, least in my case it was.

well i checked, and no spark. i pulled the cap off the rotor and there was a good bit of dirt in there and looking kinda worn... also, when i first turn the key and all of the lights come up, i get a light in the upper left hand corner that has a key with a slash through it... is that normal?

The key light is for your sentry key. It is testing the key to make sure the code matches. It should be coming on every time you start your Jeep and going off after a few seconds.

ok, then that aint it. I checked the voltage at my tps sensor and its getting 5 volts with the key on, so that means the crank sensor is ok because its letting voltage to the tps sensor... maby ill shoot for a cap and rotor and wires since it needs done anyway...

From what you describe you may have a bad ignition switch. When they go bad a lot of puzzling electrical issues come up including dash light issues, etc. as well as starting issues. And they do go bad.
