Yep, check filter first, then pump

    my experience, fuel filter then fuel pump if still acting up, if still acting up have your local mechanic/technician take a look, occationally the fuel injectors get stuck open closed or midway in between and can cause problems

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..

see that page? page 14 in PDF
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?)

Car idles fine, but sputters, bogs and dies if gas pedal is pressed.


new spark plugs this decade. (a tune up?0
the filter is part of all 60k tuneups. letting it clog wrecks good pumps.
my wild guess, its lack of fuel flow, do to old filter.
or low fuel pressure.
car is identical to a Corolla. so is not unique or rare as some Geo cars are.
the cam belt not changes, invites valve kissing piston tops. BOOM
end of engine. (costs more to fix then worth of car)
the word is bogging, my engine bogs
if if bogs WOT (wide open throttle) and dont catch up < ITS NOT THE TPS. ever.
tps bad causes short bogs, called hesitations.
The map sensor , is what measure air flow and the ECU matches fuel to this air flow.
my guess, is it does that, but fuel pressure is like 15PSI, bad.

Will start and Idle great but when push the gas pedal it just acts and sounds like its bogging down. I have replaced the fuel filter its a 1.5 4cyl automatic


You replaced your fuel filter but have you checked the fuel pressure. It sounds like the fuel pump is not putting out enough pressure to get enough gas to the engine.

1996 chevy silverado 350vortec start and idle good,but when driving 30-40 when i push down on the gas it bogs down and act like it wont to cut off.


Check your fuel pressure because that sounds like a weak fuel pumpor clogged fuel filter.The fuel pressure should be 60-66 psi with the key on and engine off.

99 chevy tahoe, 5.7 starts and idle fine, slowly give it gas it accelerates, step on the gas and it faulters, stalls sounds like it will die and bogs down


I have seen this type of problem before, this sounds like the engine is not getting the correct amount of fuel pressure it needs as you accel.the first thing is to remove the fuel filter and replace it, take the old filter and blow into it, this will tell you if its restricked. the next step will be to check fuel pressure, you will need a gauge for this test, hook up gauge at valve on the injector rail, take caution wear safty glasses as fuel is under pressure and will spary out a little as you connect line for the gauge to fuel injector rail valve, you will run the engine and also step on gas pedal as you watch the pressure, i would rev the engine to around 3000rpms and hold it to see if engine tries to stall or buck when it begins to act up look at the gauge and if the pressure drops as it starts to act up then the fuelpump is bad. its not able to keep up the pressure. start there good day.

I have a 1994 Cadillac Deville Concours. The car starts fine and runs great for approx. 15 minutes and then acts like it is starving for fuel. The car will accelerate with light pressure on the accelerator...


Any check engine light or codes? My first thought would be tps or possibly fuel filter. As car builds up pressure a clogged filter would cause your symptom.

I have a 2003 chevy impala that bogs down when accelerating. Computer diagnostics are fine. Fuel line pressure test was fine, no gas leaks. No ck engine light on. Need suggestion what to do next. Dad says...


Start with the simple and replace the fuel and air filter, also check the fuel pressure regulator vacuum line and clean the MAF sensor with MAF cleaner. Start with these easy things to check and hope will bring your car back to running 100%.
