Hi Lauren the easiest way to Blead these systems is to suck the fuel through the return line at the filter. This pulls all the fuel and air through the high pressure pump and primes the injectors. This is the most efficient way to do the job. Because even a small amount of air in the high pressure pump will prevent it from starting.

SOURCE: air in fuel lines wont

Did you replace the filter and lines because of the airlocked injectors or did you get the problem after changing the filter and lines? Did you replace the injectors?

On the TDI's it takes a lot to get them bled. Even just replacing the fuel filter can be a pain. It is recommended to fill the filter with fuel through the center opening when replacing. I usually just take the old filter and pour it into the new filter. Try this and you still may have to crank it several times(many, many times). Let me know if there is any change.

Did you check to see if there is power to the glow plugs if not then that may be the problem and if there is power when you cycle the key not to start but for the plugs to warm up you may have a bad glow plugs.

Did you loosen an injector line to see if you are getting fuel to the cylinder? Did you bleed the filter when you changed it? Was the rebuilt pump properly timed when it was installed? Are you sure all the air was bled out of the system after the pump and filter were changed? Do you have air bubbles in the fuel return line?
A copy of Haynes Diesel Engine Repair Manual, part #10330 ($20) could prove to be invaluable to help you track this down. It has excellent coverage of GM 6.2 and 6.5 engines. Hope this helps.

My landcruiser is a diesel and there is no fuel getting to the primary filter what could the problem be and the truck wont start

From your discription of your problem, lack of fuel to the injectors is your primary problem. You need to first check for air leaks from your fuel tank to the pump. After you have corrected any problems found (no matter how small) check you pump to be sure it is pumping. remove it and put a finger over the suction port and depress the pump actuator arm and you should feel positive suction. If not, replace your fuel pump. If at this point all is good, check for leaks between the pump and primary fuel filter and so on to the injector pump. If all is good to that point you need to bleed each injector at the cylinders. crack the nut at the block and have someone turn the motor over with the starter until fuel and no air bubbles come out around the nut and while engine is still spinning, tighten the nut securely back to the engine block. do this with all injector lines and you should be running when the last line is bled!
good luck

Yes it could be the pump, but also it could be a leaking injector or a clogged up diesel filter.

If the injectors are leaking they will be sucking in air and forcing the fuel back to the tank,

you can pour water around each injector to see if any are bubbling. Get the fuel filter changed and have the system bled through before replacing the fuel pump. they are very expensive.

Hope this helps

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.
