How do you bleed a diesel pump jeep Cherokee turbo diesel 3.1 5 cylinder 2001


we dont have this engine here, USA.
but i have the WG jeep book,
starting page 12 , chapter 14


FUEL INJECTION PUMP BLEEDING
(1) If the fuel injection pump has been replaced,
air should be bled at the overflow valve before
attempting to start engine.
(a) Loosen the overflow valve (Fig. 18) at the
rear of the injection pump.
(b) Place a towel below the valve.
WARNING: WHEN CRANKING THE ENGINE TO
BLEED AIR FROM THE INJECTION PUMP, THE
ENGINE MAY START. PLACE THE TRANSMISSION
IN NEUTRAL OR PARK AND SET PARKING BRAKE
BEFORE ENGAGING THE STARTER MOTOR.
CAUTION: Do not engage the starter motor for
more than 30 seconds at a time. Allow 2 minutes
between cranking intervals.
(2) Crank the engine for 30 seconds at a time to
allow air trapped in the injection pump to vent out
the fuel injector drain tubes. Continue this procedure
until the engine starts. Observe the previous WARNING
and CAUTION.
(3) Tighten overflow valve.
HIGH-PRESSURE FUEL LINE BLEEDING
WARNING: THE INJECTION PUMP SUPPLIES HIGH-
-PRESSURE FUEL OF APPROXIMATELY 45,000 KPA
(6,526 PSI) TO EACH INDIVIDUAL INJECTOR
THROUGH THE HIGH-PRESSURE LINES. FUEL
UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE
THE SKIN AND CAUSE PERSONAL INJURY.
WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE
CLOTHING AND AVOID CONTACT WITH
FUEL SPRAY WHEN BLEEDING HIGH-PRESSURE
FUEL LINES.
WARNING: DO NOT BLEED AIR FROM THE FUEL
SYSTEM OF A HOT ENGINE. DO NOT ALLOW FUEL
TO SPRAY ONTO THE EXHAUST MANIFOLD WHEN
BLEEDING AIR FROM THE FUEL SYSTEM.
Bleed air from one injector at time.
(1) Loosen the high-pressure fuel line fitting at
the injector (Fig. 19).
(2) Crank the engine until all air has been bled
from the line. Do not operate the starter motor
for longer than 30 seconds. Wait 2 minutes
between cranking intervals.
(3) Start the engine and bleed one injector at a
time until the engine runs smoothly.

I have a 1987 Isuzu Impulse turbo with a T3T4 turbo and intercooler installed. It won't idle. Accelerator to the floor is the only way it'll stay running. What will fix this?


well if car is stock, is it? is PCM stock and matches your turbo?
no engine stated. 4Ez1 or 4xc1, 4zc1-t (my guess last one)
there is also a EZ1 turbo too...
we start with basics.
did you run the diag flash codes yet? jumper?
ALDL pin 1 to 3. for code 12 (ok) 3 is ground wire.

Right?
1: compression ok. 150psi on all cyl? min?
2: spark timed right?
3: cam timed right?
4: all sensors reading right? (scan it for bad reading sensors?)

i can see there is no MAF sensor, so is MAp BASED
IS YOUR 2 BAR MAP READING RIGHT.?
are all these parts stock???? and matching your setup?

the map and IAT ,(and pcm tables) are used to calculate all fueling rates. The map is baro sensor. air pressure (called vacuum)
and the pressure drop, is what causes fuel rates to rise.
turbo or no turbo.

if car is not stock now's that time to fess up. ?
and full spec. of whats there. as we can not guess any of that.

the 4zc1-t
i see it has an I-tech unit and an turbo controler
and and air modulator, device, (no clues to what it does)
id recommend buying a REAL FSM to work on this complex setup.



25852667-qtce4npyt0vcvgrmwdzgcqbf-3-0.jpg

or login to alldata.com and read that huge section on diagnostic.
i see it injects in pairs too. (PCM does that)
and has DIS wasted spark coils.

Hi guys. I have a 91 pajero 2.5ltr turbo diesel. Looking for the safest but best way to get a bit more grunt out of it.any serious answers will be greatly appreciated. Cheers. D.


check that the turbo is operating as it should be Variable vanes actually moving -actuator connected and hose in good condition. Have the fuel pump serviced and have it recalibrated to a couple of % over specs. Have the injector tips replaced and the pressure set .
Check for dragging brakes pads rusted on the calliper slides. Consider the tyre sizes that you have . Have the fuel pump timing professionally set to get the correct ignition/injection point

Isuzu 3ltr turbo diesel no fuel to injectors


this is USA forum, and we dont have this car.
IT'S NOT A USA 2002 DIESEL trooper.
that and exact engine, size.
we have, 3 gas engines, 2.2L,3.2. and 3.5L
here. only and books that cover only those 3 engines.
so if a diesel dies.
what>?
check fuses.
scan it.
check filters
try test fuel to see if it runs on test fuel
test the glow plugs yet,?

if pump pressure is dead,?
check, power to the pump yet? (fuses are first)

there are 4,.6 and 8cyl. diesels by Isuzu.,
which is it>
they have names.
7 diffr. B engines, 3,xxxx liters.
and
5 diffr. 4Jxx series engines.
my guess is the engine is.
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4

wiki says.
"
European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the more problematic 4JX1 3.0-liter of 159 PS or 117 kW)
4jg2 is indirect injected
4jX1 is direct.
apples and orange diffr.! injection classes. '

learn what's under that hood, then fix it?

what country
what engine, real names, not 3L vague-ness. please.

1996 gmc seirra


These have a central port injection system. The central port injection is very finicky on fuel pressure. Spec off the top of my head is 58-60 psi. As little as 1 psi under minimum spec is enough for the vehicle not to start. You first step is to accurately measure fuel pressure with a good fuel pressure gauge. I'll see if I can't round up the actual spec for you in the mean time. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

  • This is the firing order for a carbureted.

Fuel pump


With a vehicle that old I think you should retrofit any pump that matches within reason the original specs as with throttle body injection fuel pressure is critical. If it is the same as South Africa the agent will sell you any **** to get rid of you. Try fitting a Bosch pump with a pressure regulator (set it to spec ). Please change the filter.
