Re: i got a difffernt injector pump and now my truck...
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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You will have to bleed the fuel filters then open the bleed screw on the injection pump. Physically pump the arm on your fuel pump until fuel is present at the injection pump bleeder. Then snug the bleeder closed. Turn the engine over with the starter, while cracking the injector lines open at the injector fittings, one at a time until fuel is present. Once you have fuel, snug the fitting closed and it should run at this point. let the starter rest between bleeding injectors to avoid damaging the starter
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
(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
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.
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.
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.
First thing to try with any diesel that won't start is to do a diesel system bleed. This one should be before the HP fuel rail type so start by bleeding the lift pump, then the fuel filters, then the main injector pump to lines to the injectors and lastly the injectors. Good luck.
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.
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.
just bump the ignition without starting it let sit for 20 seconds oruntill you hear lift pump shut off then shut off ignition and repeat do it 2 or 3 times should start then cummins is a self priming system has been for years even in semi trucks
