I have a 97 jep cherokee country 4.0 and can't find the fuel filter...my jeep acts like it's not getting.gas and wants to put? when im going 60 or so and i changed the fuel pump but its still doing it


if you follow the fuel rail gas line, it goes to the filter.
for sure.
4.0L 97 , we have the FSM to see all that , ive posted it 100s of times here. that link.
please explain the bog more clearly.
cold or hot engine or both.?
is it just tip-in throttle bogging , only then POWER catches, up?
while bogging can you go to WOT and see if it has full power now?
ever get a full 60k mile tune up with new spark parts. and filters.
is engine misfiring.
is engine idle too low rpm or too high with a hot engine?
is fuel old.
did car sit for long time ? unused?

"not getting gas" can be 2 things, bogging or misfiring
they are night and day different, one is like pulling a dead weight
the misfire is violent engine shaking,
see?
and 2 different diagnostic paths due to that ...

if wot is ok, then that implies fuel pressure is good. and filter.
see?

WOT = WIDE OPEN THROTTLE.
i drove a 99 XJ for 300k miles. and know it well..

if you changed the pump, you had it in your hand.
unknowing
its on top of the fuel tank pump RACK.

if engine is tuned up,?
and power is low at wot,
i check fuel pressure live.(under varying engine loads)
if the pressure is out of spec, i get a new filter and PPR.
if pressures are in spec. dynamically.
i find out why the PCM is under-injecting.
ask how. its not hard.
(bad MAP?, , injector balance tests?)

Sounds like you may be losing fuel pressure. The first thing I would do is hook up a fuel pressure gauge to the test port located on the fuel rail on the backside of the engine near the distributor. You should see more than 58psi and it should hold pressure for more than a half an hour and better yet several hours. If pressure is not 58PSI the vehicle will not start. If pressure gets up above 58 psi but drops fast than you either have a leaking fuel pressure regulator or a bad fuel pump check valve. The fuel pressure regulator is located under the intake plenum on the backside of the CPI fuel injection unit. The only fix for a bad check valve on the fuel pump is to replace the fuel pump.

most likely a weak fuel pump or a clogged filter. Check fuel pressure with a gauge or as its bogging down spray brake cleaner in the Throttle Body. If this allows it to increase RPM then its the pump or filter.

During hot days in summer, car bogs and dies now in spring.


your fuel pump is going.

there was a 10 year unlimited mileage warranty on 2000 focus for this issue, but not sure if 2001 was included. The internal filters in the fuel pump clog and starve the pump. New stlye filters went into prodction but not sure if all of 2001 had the new design.

Sounds like itr is not getting enough fuel. Try or check the fuel filter for dirt or water, and also check the fuel pump pressure to see if it meet factory specs.

Loosing power


Wow, I just went through the same problem and guess what it was a clogged converter and a bad oxyegen sensor. The garaged fixed it up for me by putting an eco converter on it and a new O2 sensor. I have a 2003 Chevy Impala,V6 3.8 engine. Good Luck!!!!
