How to change fuel injectors in a 2000 jeep grand cherokee laredo 4.7L V-8

Hey Harley..
Here is a video covering the Laredo, Liberty, and Commander line,
Jeep Grand Cherokee Laredo 2007 Replacing the Fuel Injectors

code p 0307 is misfiring on no 7 cylinder ====causes --- engine mechanical fault ---wiring---ignition/ fuel system--injector --ECT/MAF sensor---ECM
look for low fuel pressure or ignition control module

are you on wrong forum, Grand cherokee is it?
the XJ jeep is not a ZJ jeep. which is it, the big GRAND ZJ?
what a great question, actually cars with EFI all have 3 filters...
sorry to shock you.

1: the fuel sock , below the pump , to catch loose golf balls. LOL.
dead bugs, etc.
2: the pump output line has a filter., all do, can be in tank (newer cars) or just outside (did you look first or post first) bingo!
3: then each injector has 10 micron size screens. the above keeps these clean, saving $120 for injector service and labor R&R.

and what engine, not posted engine size on engine questions
the fuel system matches ENGINE type, on all cars made.
4.0L engine ????

ive owned both a grand laredo and not grand laredo 1988 to 2010

if not grand see this XJ car.
called just a Cherokee here. 1993

sounds like a fuel supply problem-change the fuel filter and run some injector cleaner through it-it also could be a bad fuel pump-Denny

Check for a feed wire from the battery that is bad. Fuseable links. Feed the fuse box directly from the battery to see if it will start.

Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

Change the crank senser first.If thats not the problem then its the coil pack.
