I am hoping this truck is a gas engine. If so probably a 460. The truck has a fuel pump in the fuel tank or tanks if so equipped. There is a fuel rail at the front of the engine that feeds the injectors. On this fuel rail you will see a plastic cap that looks like a cap on a valve stem to a tire wheel combo. Remove this cap, if you turn the key to the on position you should have air out at first and then fuel. Be very careful not to ignite the fuel coming out. Use something to catch the fuel as it begins to come out.

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.

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

Run out of gas,now it wont start


You will probably have to bleed the injectors or injector rail. Look for a bleed screw on the injector rail or loosen the injector lines to bleed out any air . Some fuel pumps have a priming bulb for this reason check to see if your vehicle has one.
Hope this helps.

Diesel pump bleeding


First off you need a good battery or jumper leads as it takes a bit of cranking. You usually don't have to do it at the pump you crack it were the hard line goes into the injector. Back that nut of just enough that you can wriggle the hard line just a little. Then crank the motor over until you see that there are no air bubbles coming out with the fuel. Then tighten the nut while still cranking, after a couple have been bleed the engine will try to run. After the engine is running repeat the bleeding process to each injector again. It does help if you can hook you some low pressure air to the fuel tank and make sure that the fuel has reached the filter and pump before you start.

Bleed deisel fuel lines


On the top of each injector were the fuel goes in there is a nut that you turn anti clockwise about half a turn, this is called cracking the line. This can be done with the motor running (if it will) or as you are pumping the lifter pump if motor wont run. You should see diesel squirting from the top of the nut, when it looks like a good stream with out any bubbles tighten the nut back down. This is done to each injector, if you are doing this with the lifter pump just get some diesel to the injectors and then try to start motor as this is best done with the motor running as you get better pressure.

Vehicel cranks but wont start


check and bleed out any air from all bleed nipples. crack the injector line at the injectors and crank over until there is fuel dripping from the nut. tighten up as that will bleed out the ait in the injector lines . Ensure that the injector timing is correct and on the injection mark

How do i bleed the fuel line on a 2011 buick lucerne. FYI I just replaced the fuel pump


To bleed a John Deere 2240, find the bleeder port on the injector port. Crack open the bleeder port while you're pumping the handle on the fuel pump or cranking the engine. Keep pumping until you get a steady stream with no air. Be sure to keep pumping while you're closing the bleeder port screw. If you can't get it to run right after bleeding the pump, you may have to bleed the injectors. Just crack the nut loose on the injector and start pumping. Keep on bleeding until all the air is out.

Ran out of diesel now vehicle won't start


This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.

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.
