If the vehicle will turn over and try to crank but wont actually fire you have to be sure you are getting spark, fuel, and oxygen. Since it was running and then when turned off it wont restart what made you start with cam sensor. If you just got gas prior to turning off or if you were very very low on gas first thing would be to check fuel filter to see if the new gas was contaminated or if being low on fuel the fule pump picked up trash from bottom of fuel tank.. this happens when people "run on fumes" It can clog the fuel pump and or the fuel filter. Diagnosing the fuel delivery system beyond those is difficult as this is fuel injected vehicle and it would require disassembiling the injector nozzles. So if you can rule out the simple lets progress to the next level. Lets stick with the first thing you should check. 1. Since the vehicle is immobile have you a way to get a OBD code reader from a local parts store. Normally they would read the codes at the store for free, but if you cant get the car to them you can use "Loan a Tool" where you pay the price for the item on a credit or debit card as a deposit and then return it for a full refund when done. You need to get the codes the engine is throwing to the ECU to help narrow down the culprit. 2. if you cant get the code reader the next logical step is to replace the COIL PACK on the vehicle. The cam sensor, crank sensor all feed into the ECU which in turn tells the coil when to send spark down the wires. A bad coil could not be sending spark to the plugs or insufficient spark. You can check the plugs and make sure they arent fouled with oil and are in good shape. Also look for kinked, singed, or broken spark plug wires. and make sure all are seated firmly and securely. 3. Has anyone checked the timing. If you replaced the sensors yourself they have to be calibrated properly with timing on the vehicle to tell the injectors when to shot fuel into the cylinder and the plugs when to fire. If the timing is off you wouldnt run either. If you are getting spark and the coil is replaced then the fuel system needs to be checked by a mechanic with a pressure system test unit.

2002 Jeep liberty headlights cut off and then back on at random times. weather makes no difference nor hot or cold. went a way for a few months and now it has started all over again. hear clicking sound...

the clicking your hearing is the relay trying to stay engaged, its heating up causing the relay to power down, which in turn you lose the lights, the heat is caused by the electrical current supplied to the replay, Not the outside temp , locate that relay and replace it, and your problem should be gone

Jeep liberty will shut off and gives a no buss indication light on dash. sometimes restarts and sometimes you have to wait 10 or 15 minute to restart

a bad crank sensor shuts off while going down road. then restarts after 10 minutes, but only until it happens again.

My wife had a similar problem with a 2003 Jeep Liberty. Her problem was that it stalled and she could not get it restarted unless it sat off for 30-45 minutes. It seemed like it was a problem with the alternator and battery but it had just gotten a brand new battery in it and we discovered the starter would roll over after the Jeep sat. We had it towed to the dealership and they replaced the Crank Sensor and the Timing Sensor and the Jeep now runs fine again. Side note: They charged us about $200 to fix these parts.

2002 Jeep Liberty shuts off

Could be a faulty fuel pump. As the pump warms up, when you have a faulty fuel pump they will tend to seize up. When it fails check the fuel pressure with a fuel pressure gauge and see what it reads.
