Could simply be trapped air. Turn the key from OFF to RUN then wait and listen. Dont try to start. You should hear the fuel pump (humming sound) run for a few seconds and then stop. If no humm, no pump, no fuel.
If you hear the fuel pump cycle on/off then turn key OFF and back to ON, wait for pump to cycle to off, and repeat a few more times. Then try to start.
If still no start, then the fuel system may need to be bled
You don't say if you have checked that the Fuel Pump is working.
1. You need to check that the fuel pump is operating and getting power.. Have someone turn on the ignition (but not start the engine) If you listen near the FP location you should hear the fuel pump run for 3 seconds and stop. If in doubt do this a couple of times until you can hear the pump run and stop.
2. If you cannot hear the pump running check the fuel system related fuses.
3. If the fuses are good check that the relay for the fuel pump you replaced is functioning. Have someone turn the ignition on and off a few times and listen for the click from the relay or put your finger on it.
4. As a final check have a simple fuel pressure test done on the fuel system if not done already. . If everything is running normally and you are getting good fuel pressure then the starting problem will be somewhere else.
Could be the fuel pump. Can you hear it run when you turn the key on? If not sure, pull the gas cap and listen there. If you don't hear it. Hit the bottom of the tank about where the fuel pump would be. If it starts then, replace the fuel pump. Running out of gas will kill old fuel pumps. Check the plugs for spark. No spark, read the codes. Could be coil/s or crank sensor.
Try taking the relay out and putting it back in. If that does not work, you should try to replace the relay. this has happen to my wife's car before. on 04 kia rio
3 THINGS WILL CAUSE CAR TO SHUT OFF ON HIGH WAY.LIKE ALTERNATOR - FUEL PUMP - SPARK IGNITION COIL OR MODULE.FIRST OF ALL IF YOU HAVE DASH LIGHTS AND HEAD LIGHTS.ALTERNATOR OKAY YOU GETTING POWER.LISTEN FOR FUEL PUMP TURN ON IGNITION SWITCH ENGINE OFF LISTEN TO HEAR FUEL PUMP RUNNING IN GAS TANK.IF YOU HEAR NO PUMP RUNNING IN GAS TANK.CHECK FUEL PUMP FUSE AND RELAY.BOTH CHECKED OUT GOOD MORE LIKELY FUEL PUMP AT FAULT.IF FUEL PUMP RUNNING CHECK FOR SPARK AT PLUGS.IF NO SPARK.CHECK IGNITION FUSE.IF FUSE GOOD YOU COULD HAVE PROBLEMS IN THE PCM SINCE IT CONTROLS SPARK IGNITION SYSTEM.
most newer cars it is located inside the fuel tank generaly when a fuel pump goes out its just done no more running occasionally, you will get a fuel pump with a short in its wiring and it will intermitantly not run such as i hit a bump it quit and later on it started and ran until the car was jostled again and once again quit this on is rare, but a possibility to check your fuel pump with no tools, open your fuel cap and listen carfully while someone turns the key to the on position when the key hits the on position you should hear a buzzing for about 3 seconds, if you hear this the fuel pump is working if you dont you may have a dead fuel pump good luck
may be the fuel pump check for power going to the fuel pump if there is power then listen for the pump to come on when you turn the key to the on possition this will be a humming sound comming from the rear of the car
Alarms usually won't allow the engine to crank. If it is the alarm, arming then disarming it usually gets them to start. However, you probably aren't that lucky. Probably the most common problem for Cherokees with ignition issues is a crank sensor or a fuel pump. Listen to hear if the fuel pump runs when you turn the key to the run position (it will only run for 2 seconds, so have someone else turn the key while you listen at the gas filler neck)
I agree with you that there is not fuel to the engine.Fuel pump can still work but not delivering fuel because fuel filter is dirty.
To check if fuel pump is turning on, listen to the fuel pump for 8 sec for priming at the time your ignition key is at on position, not the start position. After that it will be off until you start cranking. Have a helper stand near the gas tank to hear the pump. If there is not fuel pump sound, then it is a bad pump. If there is pump sound then it is a dirty fuel filter.
are they good in the way that your getting power with a test light or volt meter?? if you are getting 12 volts with the ignition on or if you can actually hear the fuel pump relay clicking then its probably the pump itself or the wiring from the relay back to the pump. see if you can get at the wiring at the gas tank and try for voltage there with the ignition on if you get voltage then you have pump problems for sure
