Alright well first off try and locate the manual primer on your engine..many of them are right on the fuel pump
usually on the bottom a few on the side.....its just a short lever with about an 1" throw...some of them are independently mounted or... on top of the secondary filter housing...usually with a 1" round button type plunger knob....Just find it for now...but if its on the fuel pump give it a couple pumps to see if the cam is in the right position to be able to pump...you can tell as it well have resistance during the whole throw of the leaver...If it feels to easy and like its not resisting you at all the cam has the pump actuated and you need to give the starter a very quick hit with the key switch to move the cam lobe a bit..It might take one or two bumps to get it right.
Next if you can spin off the secondary filter and fill it manually with some diesel it will save you some pumping...and
you will know its full.
Make sure you have enough fuel in the tank and it is turned on if you have an in line shut off at the tank or at the racor
Next Follow your injector lines leaving the injector pump to the top of your engine...the first nut you come to is the top of your injectors feed fuel supply..not
necessarily the topmost nut on the injector as that is usually your fuel return lines banjo bolts..leave those alone
...Crack all the nuts of the lines you followed at least 1/2 turn no more then 3/4 turn is ever needed...the Nuts generally are 5/8 to 11/16" in size or the metric equivalents..every manufacturer has their own specs.
It helps to have a second set of hands or a remote
starter next but not a deal breaker if you don't.
Now start pumping...as soon as you feel it pressure up have some one try and start the engine...keep pumping if its a remotely mounted primer pump or on the fuel filter housing..if on the actual fuel pump stop pumping during the starter cranking...make sure its out of gear
but with the throttle advanced just a tad bit..you want the injection pump off the kill position and able to get fuel.. wide open is not necessary and hard on the engine anyway at start up ..just a bit more then a fast Idle is good...now watching where the lines go through the nuts you just loosened crank the starter for no more then 15 seconds at a time but don't stop pumping...after 2 or 3 starter spins you should/will start to see air bubbles and fuel seeping or squirting from around the lines through the nuts...as soon as the bubbles stop and clear fuel comes form any one of them tighten that one only and keep going...by the time you get the 3rd one running clear and tightened she will probably fire ( if it a 4 cylinder)..if it does just reach over with it running and tighten the last one up ..she will quit stumbling and start running like a Swiss watch.
If your by your self its tougher to see whats going on with out a remote
starter...which you can buy for 15.00 ant any auto parts
Piece of cake eh?
