SOURCE: Diesel fuel pump/installation

If we're talking about the thing that has a pipe to each of the cylinders on your engine then the answer is Yes, your injector pump must be correctly timed in order for the engine to run properly. This is the part of the diesel that does what a distributor on regular car engine does, namely ignition timing.

The exact procedure for setting the timing depends on what model of engine you have, get a manual from Perkins to be sure.

That said it usually goes like this:
1 - make sure the engine has the correct cylinder at TDC, this makes the gear connected to the camshaft be in the correct position.

2 - Set the pump at the correct position, this will either involve looking at a mark in a window on the pump (standyne pumps), or looking at the keyway in the shaft of the pump, etc.

3 - Bolt the pump into place on the engine making sure the gears/drive meshes nicely. Connect all the fuel lines to the pump.

4 - purge the injectors by loosening each fuel line at the cylinder end and cranking the engine until fuel comes out of the pipe, then tighten it back up.

5 - Crank the engine and start it, check the rpm.

Rank this answer if it helped,
Carl

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.

Make sure that the idle is set at 40Hz. You do this by placing a frequncy meter on one of the 120Vac outlets. If frequency is low, the engine will run rough at idle. There is a 3/8 nut next to carberator that needs to be turned to the right to increase the idle speed.

How to bleed the fuel system in a John Deere 318D?


The first question is did you run out of fuel? if so you will have almost certainly dragged all the debre, sludge and jelly from stale fuel into the system. remover the fuel filter and ensure that diesel is flowing freel into the fuel filter assembly head. If not blow back through the pipe into the tank with an air line to push the debre back into the tank. Alternatively (and I prefer this method) remove the fuel roll up some rag around the air line, leaving the nozzle through the rag and bung up the filler hole making the best seal you can and pressurise the tank in very short bursts of air. this should force out the debre and jelly in the pipework and out of the inlet of the fuel filter. (then you have less rubbish in your tank for the future). fit a new fuel filter (don;t be tempted to use the old one). then bleed the filter by removing the uppermost bleed bolt. (you can short circuit the filling by putting as much clean diesel into the new filter assemble before you assemble it.) when clear diesel runs out of the bleed screw, retighten. Follw the pipework to the fuel pump and bleed this by losening the bleed bolt on the top of this. If there is a manual primer (usually a lever at the bottom of a glass bowl). use that to push fuel through the system, if not get 'another' to turn over the engine for a few seconds at a time . ensure that fuel comes out is air and bubble free. Tighten the bleed screw. loosen each injector pipe where it joins to the injector starting with the nearest to the pump first and pump or turn engine until fuel is squirted out in time with the the timeing of that piston. Tighten right away - repeat on the other injector pipes. Now you are ready to start. Some engine need a little help with a squirt of easy start to fire and overcome the small air gap at the top og the injector, some don't. If you have a cold start or excess fuel button use that first and only use easy start as a last resort. BRUUMMMM -(hopefully :)

1995 international flat six diesel 466 wont run changed fuel filter losend lines bleed out air wont run squirt eathier starts dies


Make sure you pre fill the filters with clean fuel. Locate the hand primer usually near the fuel lift pump. Unscrew the top till it pops up. Pump repeatedly until it gets hard to pump. You can crack the injector lines while pumping till fuel comes out or have someone crank the engine with the starter while you continue to pump the hand primer. Make sure after it's running the pump is pushed all the way down and tightened back up

My 2002 chev. diesel truck turns over but wont start, new filter


anytime you change the filter in a diesel you have to bleed the air out of the fuel system. The pump won't auto bleed the fuel system for you. every place in the fuel system that has a flare type connection needs to be bleed, start at the connection closest to the tank, loosen the connection and then crank the engine until you see diesel fuel drips from that connection. Tighten the connection while the engine is still cranking. Move to the next connection that is going toward the engine. Continue on in that manner toward the engine until you reach the injector pump/injector. Once you reach the injector pump be VERY aware that the fuel is at VERY high pressure. Do NOT put your body parts in the stream of high pressure diesel fuel. It could kill or injure you! Once you bleed all the way to the injector pump/ injector, the truck SHOULD start. Do not bleed after the injector pump because of the pressure involved, it is WAY too dangerous.

Good luck!

I put gas in my 2005 3500 diesel truck (chevy) and a mile down the road the truck just shut off. So i pumped out all of the gas, then put treatment and diesel back into the truck. Tried to start the truck...


Did you change the fuel filter or bleed the injector lines? You need to get that gas out of the system if you haven't already. Once the filter is changed and filled with diesel I would loosen the injector lines and crank the engine until the gas is cleared out of the lines. Tighten the lines and see what happens.

I have an F-350 Super Duty Diesel V8 2008 and we ran out of fuel. When we put diesel in it throws out black smoke. How do you check the Fuel pressure? It won't start and we just changed the fuel filters....


Make sure you fill the filters with fuel before you install them. then bleed the line at the fuel filter then move
on to the injectors
loosen the injector line to bleed it one at a time then crank it till no air is coming out tighten that line then do
the next one. . Dont use starting fluid to start it if you use any spray use wd40 for priming I havent worked on the new ones but the 7.3s will start that way

Truck wont start after draining fuel filter?


You may have gotten air in the fuel lines. Diesels cant deal with this as well as gas engines should be a purge / bleeder valve on the fuel lines to eliminate the air. may cough and sputter for a while
