Check the fuel solenoid is getting power. It may be locked out by loow lube oil pressure and other things.

ALSO when restarting a diesel one OFTEN must "bleed" the fuel lines at each injector... same as when one inadvertently runs a diesel out of fuel. Crack the connectors at the injectors and crank till fuel comes out and tighten each one. Yes, it is a pain...

The diesel generator set first puts the stuck fuel injector into diesel or oil, then takes it out and wraps it in the cloth, then clamps the needle valve. The pliers move slowly. Remove the needle valve from the needle valve body, and drop a small amount of cleaning oil in the needle valve body to repeatedly move the needle valve in the needle valve body until the needle valve moves freely in the needle valve body, such as the burn surface of the needle valve. The abrasive paste should be used for grinding. When grinding, pay attention to the amount of grinding paste and grinding time. Install the cleaned valve valve connector on the injector and adjust the injection pressure for reuse.

MF 135 3 cylinder Perkins motor. The engine sounds to be missing when under no load; under load she sounds to be firing satisfactorily. The injectors have been serviced and are said to be fine. The

Any engine runs better doing what its built for, but it should not be very noticeable. If you are familiar with this engine, then I would tend to go with your instincts. The injector timing is a likely cause and could be supplying more fuel than you need creating a laboured combustion which evens out under load.
Perkins parts were found everyware around western Australia 20 years ago and were cheap, I'm a bit out of touch on that aspect these days, but they are worth the effort, you should try to find some old school farmers around to speak with, they often have golden and unique solutions.

Perkins 20 kva diesel generator runs and stops in about 2 minutes.alternator failure is displayed on screen.

Ensure any engine control switch is set to the run position, with the load disengaged. Manually set the air shut off valve (if fitted) to the run position (see Fig. 18), Turn the key switch to the start position, which will energize the solenoid allowing the engine to crank over for a few seconds then start.

Check the instrument panel is showing normal running oil pressure, and the ammeter for charge to the engine batteries.
Allow the engine to run for five minutes checking the instruments are reading correctly. Stop the engine and check the oil and coolant levels, replenish if necessary.

I have a audi a3 2000 w reg 1.9tdi the problem is its hard to start in the morning when i get it started it runs perfect then if i try to start it hot the problem is the same takes a few goes to fire up ....

i think the problem is the injector pump ,this isnt common rail as yet for this age vehicle and when its starting its not throwing the auto start mechanism into play which makes it over inject fuel ,remember the old transit with the inline injector pump,lift bonnet pull throttle and push button in ,then it would go first time .well its the smae thing buts done electricaly ,only solution is to put car into a bosch injection specialist and have the pump overhauled ,lots of cash though,or use a can of brake and clutch cleaner --- and thin pipe into teh air intake and spray some of the cleaner into the air intake ,brake and clutch isnt as harsh as easy start andf their is a nozzle on the can so the pipe pushes onto that ,just like the old perkins diesels in the transits in the 60s only it was a plunger on the dash in them days .

All four injectors stopped working

Try the carb cleaner fluid by mixing it with the fuel or spray it at the intake. After cranking the engine a few times, wait for a while and if the engine refuses to start, get some young men to try & start it by rolling the vehicle & turn on the ignition(i.e. if it has has manual gear shifting) till the carb cleaner has got a chance of forced into the injector to clean the nozzles. If this fails then it(injectors) cleaned by maul removal & cleaning/replacing the injector nozzle tips by a qualified mechanic....sodeep
