I went away on vacation for 2 weeks and tried to start my 2004 Cherokee it's turning over but not starting any suggestions ?

 

Check the battery voltage. You may have enough voltage to turn the engine over, but not enough to supply the fuel pump and ignition voltage to function.

 

Welcome to CF. X2 on what Bustedback stated above.
How old is your battery? They usually need replacing about every 4-5 years. Some only last 3 years before giving trouble.
Give your cables a good cleaning.

 

The Battery wasn't great so got a new one, I have fuel coming up but no spark to the plugs, I'm not used to these modern cars could it be some kind of sensor or coil problem ?
Cheers

 

Do you have a 4.0?

If so, could be a coil or crank sensor.

 

check the cam sensor and remove it check for metal around it this happensi just did one that died out of no where metal got on it cause they are magnetic so clean the sensor and if that does not work change the cam sensor is only like $24

 

You might want to check out the ASD relay and the security system. You may have fuel pressure in the rail, but no power to the injectors. Pull a plug and see if it's wet with fuel or pull an injector plug and check with a voltmeter while cranking.

Remember the Fire Triangle. Fuel, Air, and Spark.

 

Thanks to everyone for their help, it was the cam sensor I bought one and fitted it in a few minutes, thanks to the people and this forum I'm up and running again
Cheers !!

 

Glad to hear you've got it fixed. Thanks for posting the cause of the problem.
