so i am confused to as why my cherokee wont start and im about to run out of money so i need some help

the engine is turning over and it is trying to start but it wont actually run it cranks over just wont start and it randomly started this the other day, i started the jeep no problem and got a little down the street and it started bogging down like it wasnt getting fuel kinda like when you run low on gas, it has half a tank in it and i have tried replacing the map sensor cause the code came up at one point and it made no difference i have replaced the fuel pump along with the fuel filter and still no change so i dont know what else to check, the spark plugs, wires and cap and rotor were done back in oct.

if anyone has any suggestions please let me know...

 

Check for fresh codes.

Post the EXACT code numbers here for comment.

If you have a starting problem and a code, it is not likely a coincidence.

Have you pulled a spark plug and checked to see if you have a "strong, blue, snapping spark". Spark quality is important here.........

So is verifying fuel pressure with a gauge at the schrader valve on the fuel rail.

But get us that code first thing......
