Diesel Injection pump for Jeep Cherokee - Cherokee Jeep Cars & Trucks

2001 ,? 2.7L USA jeep???????
my guess it cranks ok.
fuses ok
immobilizer not active, SKIS/SKIM.?
so compression is at spec.
and if it is ,test fuel diesel works?????
Glow plugs work? (we measure current)
then filters
then pump
scan pcm for errors, not all errors glow the silly CEL lamp.
page 1269 in jeep manual, usa, 2000

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.

pump timing is on next page
or tank filter line priming before. above.

does it start and run for 3 seconds on test fuel

yes, engine ok, EFI bad.

no, bad engine, engine must be good to run.

EFI cant run bad engines..

so compression at spec......????



why beat the EFI to death,

all engines run on test fuel.

with gas engines, takes spark and good engine

on diesel, takes only good engine. simple huh (and some air)



for test fuel try diesel in a spray bottle into the injection port.

google this

or use youtube on test fuel on any diesel car. or truck



this is called basics....... basic basics.

1: good engine, and pumps air ok. (must breath)

2: good fuel.

3: test fuel works now. if not check above.

for what? WJ sure.

3.1 liter turbo diesel.
2000.
our books (USA) don't cover diesel , we dont have it. try EU, forum for help.
we have GAS.
the wiki tells me this.
I'd not touch it with out your real FSM on this. from JEEP (your country)
my guess a supplement booklet on this TD? at Jeep.

quote:
The 3.1 litre turbo-diesel on the 1999 Grand Cherokee was developed in conjunction with Detroit Diesel/VM Motori. It has an electronic injection pump, electronically-controlled, vacuum-actuated exhaust gas recirculation, and a special catalyst to control oxides of nitrogen (NOx). Manufactured in Cento, Italy, at 13,000 units per year. It was available in European models and meets the European stage III emissions.

• Displacement: 3,124 cc (191 cu in)
• Power: 104 kW (141 PS; 139 bhp)
• Torque: 367 N·m (271 lb·ft)
• Transmission: Four speed electronically controlled automatic

MOST PASSENGER VECHICLE FUEL INJECTORS INDIRECT.THE BIG DIESEL TRUCKS HAS DIRECT FUEL INJECTION SYSTEM.FUEL IS INJECTED DIRECTLY IN THE CYLINDERS.

Drain all the petrol on your tank and so on the injection pump by pumping it. Open or loosen small tube going into the engine from the injection pump, to drain all petrol.

Make sure that petrol are remove from the engine fuel system, change fuel filter also. After removal bleed the engine.

Change fuel filter and air filter. If that doesn;t help you may have a fuel transfer pump pressure problem.

turn ignition to on and see if it you can hear the fuel pump.
if yes check for blocked line/filter or leak somewhere
if no hard wire fuel pump and see if car starts.
if yes then your not getting power to your fuel pump, probably due to immobiliser but possibly due to faulty wiring.
if no then replace fuel pump.

it could be that one of the injectors is bleeding off pressure not allowing enough fuel pressure to start. the 5.9 and 6.7 cummins need at least 2000 psi to start

isusu engine?? have you looked for a 8mm hole in timing gear that corresponds with a hole on plate behind then lock it in with a bolt ,remove bolt after tightening belt .DONT FORGET THIS ???.....if you cant find anything do it with no timing marks easy --- piston no 1 at tdc valves closed spin pump till fuel comes out of no 1 injector feed and lock it all together,indirect diesel is 6/8 ,,,,,direct injection is 12/16,,,,and turbo is 18/22 btdc
