The inline fuel injecter is messed up, do i have to drop the gas tank on a 95 grand jeep cherokee?

95 ZJ JEEP, USA ANSWER NEVER OTHERS.
car fell over to its side? what does sideways mean to the blind?
off road'ing it? OR simply parked with drivers door looking up hill
I can NOT see the car, parked. nor why the hint it matters unless
tank is 1/8" full or less. ???
did you run the tank drY, this can wreck the pump doing that.
the PUMP is fuel cooled and fuel lubricated, so never run one dry.

4.0L inline 6 engine? (I have full shop OEM manual on it (ask)
OR 5.2 LITER? NOT THE DIESEL.
cranks fast but will not start and stay running?
or
starter is dead and will not crank the engine.?
I CAN NOT HEAR YOUR STARTER MOTOR SPIN ! SORRY

pump that make noise vast times can be no good,what matters
IS PRESSURE AT SPEC. (ASK) ( A TOOL)
picture A pump motor spins but impeller blade now dust inside)
bingo, and the new BOSCH pump are now silent, Oops tech changes happen.

THE most key factor is fuel pressure never the noise. (devil danged the prime pulse)
first is a good engine the 4.0L only breaks if dropped off a cliff
drove 3 me for over 500k miles. one sold at 300k. 1988 up.
1-engine good
2-spark then must be good to all cylinders not just 1
3-and last fueling can't burn gas , lacking spark. (otto cycle tech)

THINGS TO CHECK ,
ALL FUSES GOOD.
TANK AT LEAST 5 GALLONS FUEL FOR SURE ON HILLS. STEEP
KEY ON, DO THE CLUSTER LAMPS WORK?
DO HEAD LAMPS WORK EVEN KEY OFF? THEY MUST
IF ALL IS DEAD FUSE 12 AND 13 ARE BLOWN
JEEPS HAVE THIS RELAY CALLED ASD
IT IS REALLY SAFETY RELAY TO STOP CRASH AND BURN
IT GOES OFF LINE , WHEN THAT HAPPENS AND KILLS INJECTION DEAD. REGARDLESS OF 20 GALLONS OF FUEL IN THE TANK AND 10 NEW PUMPS.
THE ASD DROP WITH THE FUEL PUMP RELAY TOO
THEY ARE WIRED IN PARALLEL THE 2 RELAY COILS
THE PCM TURNS ON AND IF SPARK FAILS PRIMARY SIDE
IT CUTS FUEL , FULLY AND THEN KILLS SPARK COILS DEAD.
SEEMS ODD THAT BUT IS NOT,
THE SPARK TESTS MUST PASS, OR ALL FUEL AND SPARK COILS ARE DISABLED. VIA ASD.

IF SPARK IS OK
TRY TEST FUEL CALLED INSTANT START IN A SPRAY CAN

THIS IS THE SHORT STORY. WE CAN DO MORE
50 THINGS CAN FAIL TO MAKE AND ENGINE DEAD.
IF ONLY THE STARTER FAILS SAY SO, 6 CAUSES AND SIMPLE TESTS. NEXT. ASK
I HAVE ON HAND ZJ SERVICE MANUAL OEM JEEP
do not remove the distributor as that messes up injection timing.
new cap,rotor,wire set and plugs , yes! called tune up+ filters , fresh and full engine oil?
those spark parts never ever lasted 28 years. sorry

I replaced the fuel pump in a 1995 Jeep Cherokee Sport without having to remove the gas tank. Maybe you can too in your '98 Grand Cher. If your fuel pump is accessed from the upper front of the gas tank-above the rear differential-then you should be able to remove the pump with the tank in place. It was easy on that jeep of my son's, took only about an hour or two.

The fuel pump is starting to go bad

Hoefully the fuel filter isn't ten years old

Does it do it when the gas tank is all the way full?

Its in the gas tank

Yes you do, fuel pump is in gas tank.

all late model cars have fuel pump in the gas tank.
have to drop the tank under the car to get to it.

The fuel filter sits on top of the fuel pump. It is the fuel fuel filter/fuel pressure regulator. You will have to drop the gas tank to access it. Hope this helps.

Best of luck

the fuel pump is in the tank and along with the fuel filter

I used to drive to mexico quite a bit in the mid 90's. Their fuel always had water, so I learned to carry a product like this:

It's a Gas Dryer and Anti Freeze, it works great. I would also just top off the tank with fuel and add an octane booster. Good luck.
