Will not start after ran out of diesel and lose oil pressure


You have provided little information to go on here JBM but some diesel engines (depending on year, make, model) require the injectors to be manually bled to remove the air in trapped in the fuel delivery lines after running of of fuel.

Check the (owners manual) to see if your engine is self bleeding.

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.

Aireated fuel after cold soak


check for a loose fuel line hose/connection that is allowing the fuel to drain back over time and filling the line with air that is causing a air lock when trying to start

1998 nissan altima brakes to the floor


Still air in system, sounds like the master cylinder has ran dry during the bleeding process, pumping more air into system. The lines running to the rear brakes are long, so you must bleed the fluid out the bleed screw in the rear 10+ times each side. Bleed, bleed, and bleed some more, keep bleeding untill that pedal feels good.

Brake pedal goes to floor


for the pedal to go to the floor there is still air in the brake system. Start again starting from the longest line bleeding each in turn to the shortest line . make sure you have adjusted up the rear brakes before bleeding as every time you press on the pedal the shoes expand right out and when you take your foot off the pedal the shoes go all the way back in. adjust them manually and do not rely on the self adjuster as it only adjusts on wheel movement

Help I have a 2003 Kia sedonna that is fuel injected. I ran the car out of fuel. put in a new fuel pump bled the lines and got the car started. It ran for over 30 minutes has 1/2 tank of fuel. After I shut...


Fuel Pressure at motor with a gauge

No bleeding to do

Once the pump comes on you have fuel pressure

Once the computer sees a crank sensor signal the injectors
pulse & all air is blown out into the cylinders

Ok maybe you can help i have changed master cylinder front right rotor and caliper all pads and shoes on drums and power brake booster and can not get the brakes working ...we have bled and bled and bled...


bleeding hydraulic lines is tricky. get someone to help you. get a big bottle of brake fluid, and don't be stingy.it takes a lot of pumps to pass air from front to back of truck. start at the furthest wheel and bleed first. use a clean water bottle punch 1/4' hole in cap use 2 ft of clear 3/16 tubeing, stick it in the cap and submerge in the water bottle which you will fill 1/3 with brake fluid. by submerging the end of the tube this will allow air to bubble out, but it will **** fluid back.you can see the air bubbles come out. All the while someone keeps an eye on the mastercylinder, do no let the mastercylinder run out or you will pump new air in....keep toping off and pass plenty of brake fluid. You will end up with no air and brand new brake fluid

Brake pedal goes to floor.......pads, rotors and calibers are new, lines have been bled.


Sounds like it is not completely bled. I would bench bleed the master cylinder first and then bleed to whole system again. The calipers take quite a bit of fluid and it sounds like you may have ingested air during the bleeding process. Start from the left rear and then right rear, then right front and then left front. Make sure you keep the master cylinder full during bleeding because it can **** air if low and you will not notice. It takes a while to do it correctly unless you have a pressure bleeder.

I bought some diesel but got gas !


This is NOT good! You can try bleeding the fuel system first. More than likely, air is trapped in the fuel lines, injector, and injector lines. Bleed at the fuel pump, (On the fuel pump to injector pump side), then the injector pump, then each line.

(You have to loosen the fitting to each line to each part, then when the air is bled out, and fuel comes through steadily, close it)

I also suggest an attorney to resolve the problem, as there may be damage. Pistons could have holes in them. Do a compression check.

Usually diesel's have 16:1 ratio compression. Today's gasoline engines have anywhere from 8:1, to 8.5:1, to maybe 9.0:1, (Maybe)

I'm willing to bet though, that you just have air in the system, and it needs to be fully bled out.
There is NO half stepping on this!
You have to start at the source, loosen each fitting, bleed the air out, and continue on down the line.
