Any diesel mechanic gurus on here?

But you're perfectly willing to waste even more more time typing idiotic reasons NOT to just explain the problem. Yep, you're a real brain trust, there, mister.

I'd be glad to think about any problem you post and offer any suggestions I can come up with... IF you'll go ahead and POST it. There's absolutely no rational, sane, intelligent reason to not just throw it out there and watch for results.

Why dintcha just SAY so yesterday?

Crack open a fitting at each injector and bleed the injector lines. If you have air bubbles in the injector lines, the pump's "shot" on each injection stroke is not enough to compress the bubble enough to force it out and into the cylinder when the cylinder is under compression. So the bubble just compresses and re-expands without actually going anywhere. Cracking the line open at the injector allows the injection pump to force the air out while working only against atmospheric pressure.

Is there fuel in the tank?

You see, kid, that is why Usenet is full of folks who waste your time.

Now, grow up and buzz off. You can't contribute anything but hatefulness.

Nah, you are not qualified. In other words, you are not capable of helping with THIS problem. All you know that there is air in the system.

Now, run along.

Yes, it is turning or I would have said that it is not. To put it succinctly, there is no fuel to the injectors.

I, too, believe it is a Rossa/Stanadyne.

Don't have a fuel pressure gauge -yet but, it was running with the same flow to the pump as now as determined by eye (yes, I know but, it should at least run with some amount of flow) and that was manually pumping it.

No, yours is not a silly suggestion when you suggest that the pump may not be turning but, just look at the kiddies who have nothing to offer but silly, childish remarks - Usenet is full of them.

Thanks.

No, Noozer, there is no fuel in the tank. Should there be?

Why 'shuffle off'? Stay around for the circus and watch - already, we have a number of clowns.

Btw, why did you think a medical condition was involved?

Seems like the only one here with any 'snap' is cyberzl1

That otto stir the gutter.

If it was running when you pumped fuel to it but isn't now then you either have a bad pump with low pressure, or you didn't bleed the entire system. ANY air in a diesel will cause problems.

Please read and understand my previous posts.

Well, you 'Sure' don't say you bled the airlocked injector lines....

Maybe it's 'you' who should grow up and learn how to use usenet eh?

Maybe so but we will see about that.

Now, look, why can't SOME of you read and understand something? I never said that the lines were air-locked. You just pulled that out of the cosmos.

LOL!

If the pump and the lines to the tank were dry and we must figure they were because you had to bleed the tank line you say and no fuel is at the injectors, then it naturally follows that the rest of the system is dry....

I mean it sure don't take a rocket scientist for that one....

Here is your post: Can't get fuel from the injection pump to the injectors. Bled air from lines up to pump.

You really ought to quit as you continually lose ground.

Tell you what, if you ever get out of the honky-tonks with your holey and stained undershirt, do a google (know what that is?) for the soup nazi. He is a guy in NYC that supremely insults his customers while they pay him money to eat his soup and insulting them.

You must like it as you simply keep begging for it. Deductive reasoning when reading my posts or any, for that matter, is not your strong suit.

You also drag others into your folly when you say "we". You also say "IF" as in 'if the lines to the tank were dry.......".

Nope, sonny, quit before you go and show more of your inabilities.

Also, Cyberzl1, is there a bleed port on this pump? I see a screw very near the mounting base and I removed that but have not had a chance to re-pressurize the system to see if fuel comes out of that screw hole.

My main question is how to bleed the air from the pump OR, getting the pump to put out fuel to the injector lines.

If I can get over that hurdle with this pump, the rest will be alright.

Thanks

What kind of a foole are you anyway? An entertaining one, that's for sure.....

If the lines from the pump to the tank are dry and you had to prime the pump so it was also dry, then the rest of the freaking lines are dry too. The fuel just syphons back to the tank as the air was introduced or you used it all up when you ran out.

You are not the first fool to run a diesel out of fuel so the injectors had to be bled you know, I have personally met a few over the years.

I don't know why I am helping you, since your level of contempt for everyone is appalling...

Not exactly sure what screw you are referring to. If it is perpindicular to the axis of the pump it is the timing sight hole for the pump.

Typically the way I bleed out a diesel system(merely my method, I make no claims for it's true correctness) is as follows:

At this point the engine may begin to start firing(maybe give it a shot of ether to give it a boost).

The system won't be totally purged, but it will be "good enough". It will clear itself within 30sec or so of starting.

You could try pressurizing your tank to push fuel too. An air nozzle and a rag will suffice. 30# of air pressure in a tank will give your fuel pump quite a boost. It works well for those tought to prime systems.

How are your filters? What looks ok with no backpressure may not be enough pressure/flow in operation.

Is your fuel pump weak? See above.

Mike,

You are a prime, gold-plated example of a person who is so damned dumb that they don't have any idea of just how dumb they are.

YOU MAKE ASSUMPTIONS AND DON'T READ WHAT I SAID OR YOU SCREW IT UP.

Now, quit bothering me. You are clearly unable to help or follow the thread.

Okay, Cyberzl1,

I have no contempt for you. You say that I have contempt for everyone and certainly everyone would include you. Sigh.

I know how to bleed a diesel. I do not know how to bleed this particular pump.

This Onan has a lift fuel pump that feeds the two filters (primary and secondary).

I can simply disregard all of this nattering and do it the conventional way. However, I was ASSUMING that after bleeding the two fuel filters, that I could further pump fuel to the injector pump and BLEED IT without doing the inj. lines just yet.

Let's cut to the chase; as I said before, fuel is not coming out of the inj. pump under any conditions. Air is out of everthing but no fuel from the pump. I was assuming an air lock in the inj. pump.

Digressing to the contempt. This place has a reputation of a number (NOTICE: NOT ALL) idiots on here who are completely unqualified to give advice. They are qualified to show their ass.

Are you a 'ham'?
