The only thing that keeps a diesel engine from running.. OTHER THAN A MECHANACAL PROBLEM.. is lack of fuel. Since it starts when you spray starting spray the engine probably does not have a mechanical problem 1. does the fuel solenoid open when you energize it?, is the fuel filter clogged?, is the lift pump working? Is there fuel in the tank? IF YOU HAVE RUN OUT OF FUEL YOU WILL NEED TO BLEED THE AIR OUT OF THE FUEL SYSTEM.
there will be a small hand pump either on the diesel pump or on the filter. bleed the filter out first and then open the bleed screws on the pump and pump until you get straight fuel., The pump may requiring unscrewing the handle/knob first so that you can move it up and down to pump. When finished remember to re screw it back down. crack the injector lines and turn engine over until you get drips of fuel from the nuts. continue to turn over the engine while tightening the nuts and it should start before you have finished with the nuts.
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.
1. Loosen one tube on top of the engine that are goes into the engine then pump on diesel on the fuel filter, after sometime seeing no bubbles from the diesel that goes out of the loose tube tighten tube. 2. Do this to all the four tubes..
if its a gas motor all u have to do is pump the peddle while starting and if that dont work just hold it to the floor to get the gas moveing if its a deisel will have to pore some deisel down the injectors
Check your manual for Bleeding the system. Sounds like you have air in the fuel lines. Look in your manual also at Changing your fuel filter. It will explain the right way to get the air out. Did the manual say where the cut out switch was??? That would be the switch that shuts the fuel off to stop the engine.
Before you do the next oil change,get a can of motor flush.
This is the inexpensive method the free up the rings and restore some of the compression.
Use Shell 15W40 oil
Do you know the history of your replacement engine?
When was the last timing belt change?
A loose timing chain and guide can cause injector timing problem.
Start monitoring the coolant level for protential head gasket leak.
To save time,I would do a high rpm (below REDLINE) highway ran to blow off all remaining diesel SOOT.
Let the shop to do a compression test.
DO NOT DO THIS YOURSELF.
The max psi is 1850 PSI
Stay away from biodiesel blend fuel until you figure out what's the cause of the problem.
Use Diesel Cleen silver bottle and see is there any improvement.
Add the recommend dose of SEAFOAM into the crankcase to soften the valve stem seal.
Leaky valve stem seal can introduce oil drop into the cyclinders over-night.
Mointor any oil lose from valve cover.
They need to be bleed again all four wheels but your vacuum pump may be bad since diesels don't have vacuum then have to have a pump, check that the booster one way check valve is good if you can blow thew it both ways it's bad, to bleed start from the wheel farthest away from the master cylinder pump the brakes 5 times and hold down then open the bleed valve keep doing this until you get clear fluid out of each wheel once you have done that if it is still mushy and you know you have vacuum re bleed with engine running this will help push more out with power assist. most like the hard brake pedal had to do with no vacuum check out the pump. You may also have to reset the 2 way check valve if you need help with this let me know.
a diesel engine can only cutout when overheating, loss of diesel fuel and air leak in the fuel system. if you know how to bleed or ask somebody to bleed right after it stall, then start the car, if it starts immediately then it is sucking air.
do not understand you what you mean. assuming your car was ok before you changed f/filter you need to bleed the fuel system of air. esiest to do would be to loosen fuel line at the injectors and have assistant crank the engine while you observe for clear fuel leak without any air bubbles from fuel line.tighten fuel lines and start engine. might have to repeat a few times. good luck.
