Jeep Wrangler YJ not getting fuel? Well .. luckily these YJ rigs are very simple to work on. Unlike many of the newer cars they aren't full of excessive electronics.
On the fuel injected Jeep Wranglers you have a fuel pump with a pick up screen, fuel filter, fuel pressure regulator and then the fuel injectors. Of course there are the sensors and fuel pump relay that can shut down fuel, but again they are not hard to figure out.
On the carburetor equipped rigs its even more simple. Well .. kinda. Kinda meaning that as far as parts they are easier. You have a pick up tube and screen in your fuel tank. Fuel lines run up the side of the Jeep until it gets to the fuel filter. Then fuel filter to carburetor. See .. thats simple isn't it! Well .. here is where the other part of the "kinda" comes in. When the carburetor gets worn out it will create havoc until repaired or replaced. They aren't exactly cheap either.
Doing a fuel pressure test can be a great way to diagnose your Jeep YJ not getting fuel. For the fuel injected rigs the pressure port is at the front of the engine on the fuel rail. EASY access means easy test!! Until I get the webpage built for testing fuel pressure on the injected rigs, just click this YouTube Link to see the video. Check out the fuel pressure tester image for current pricing.
If you have an older rig with a carburetor, testing the fuel pressure is still easy. Simply put an adapter in the fuel line just before the carb. Hook up the tester to get your reading.
One easy way to test if your Jeep YJ is not getting fuel is to simply press the schrader valve to see if it bleeds off good pressure. But that isn't always a good indication of having a fuel problem. My 91 YJ bleeds down pressure after a bit. Some say it is because the check valve is missing. It just happens that mine doesn't have that check valve.
One of the parts that can definitely be part of your Jeep YJ not getting fuel is the fuel filter. Its inline just after the fuel pump so if it gets clogged up you will without a doubt have fuel delivery issues!!

That fuel gauge can be a pesky rascal! There are several things that can go wrong with that system, bad ground at either under the dash or at the fuel tank, corrosion at the gauge cluster, or even a bad sending unit.

OK, again this isn't a "Jeep YJ not getting fuel" issue. But if you were having a no fuel issue wouldn't you like to easily access the fuel pump and sending unit to quickly diagnose where the issue lies? Or, if you know you have to do a Jeep wrangler YJ fuel pump replacement, you will want easy access without dropping the fuel tank.
This little mod can mean the difference between an easy fix on the side of the road or .. a real pain in the tail!!
