If its using a lot more fuel than usual its almost garaunteed an 02 Sensor. Those are located on the Exhaust Manifold's, are about the size of your thumb, and generally have 2, or 3 wires coming from them. If you can, check them for operation before you replace them as sometimes they're kindof expensive.

JEEP WRANGLER 2.6 LITER HAS LOST GAS MILEAGE


In an engine of that age, likely you have some compression loss from wear. All other components also are likely a bit out of range and fuel quality today is really questionable (adding methanol definitely kills MPG as it burns cooler and requires 2x the amount to make the same power as does gasoline).
if it happened suddenly, I'd check the sensors and pay special attention to the O2 sensor(s) as they often go out of range and definitely will kill mpg when they do.

97 Jeep Wrangler sport- Cranks, will not


Fuel flow. Either simply, a blocked fuel line (debris / filter / fouled gas) or an electronic issue. Ever let this Jeep run bone dry on gas? Hopefully not, as doing so can draw a lot of crud into your fuel lines from the bottom of the tank. Electronically, if part of the Jeep "brain" has gone bad, there may not be any fuel being routed to the engine. This most likely needs a Jeep mechanic to repair.

Jeep quits. no power to ignition switch


Sounds like the positve cable on the starter or the fuse link is loose or going bad. Check for good clean connections at battery, starter and fuselinks. This should solve or get you in the right direction.

This seems like a fuel pump or fuel filter prob. The pump more likely. Will it fire up with gas poured into the carb? If so the pump. If not, we will need to look for another prob. Don't buy parts you don't need! Frankster016
