Fuel delivery problems

So my Jeep has been stalling out left and right. I changed the fuel filter and it seemed to work. I put a good thousand miles on it or more. Then it started again when the tank got low. Any suggestions as to what it might be. I was thinking sludge in the fuel tank. I'm going to drop the tank and see where I stand. I just wanted some perspective on things to look for. I'm going to rebuild the entire fuel delivery system I think but it'll be a piece at a time because I'm perpetually broke. lol

I replaced my fuel pump and it helped. Then died again. Did the three capacitors in the ECU and no more issues. Theres a sticky on the ECU repair.

it could be the screen on the pickup in the tank, the fact that it does it worse when fuel is low makes me think that even moreso. i believe once you drop the tank and inspect everything, you'll find your culprit

Thanks guys I wondered about that screen too. Probabbly dropping the tank tomorrow so we'll see what's going down then.

Clean your throttle body too. Possable iac getting stuck clean out the little port inside the t body with some card clean or seafoam. Some times thats all it is. If you tape a fuel gage to the windshield you can see if your preasure drops out when it stalls to see if you have fuel pump problem
