Would need to see type of engine and a good look ,does it have any marks on front of engine ? if not then crank mark will be through a hole in bellhousing ,injector pump if common rail will have no marks as not needed to be timed in ,camshaft if no holie in spoke on gearwheel tand no mark on rim then remove the rocker cover and look on back of camshaft for a slot ?but no year mentioned here so ?? why didnt you put some white paint marks on gears before you took it apart

flywheel is dowled pined to crankshaft so it goes in correct position.so cant get that wrong unless someone has removed dowel pin.
timing mark on front pulley in middle of pulley aligns up with mark in front timing cover, and cam should have dot or "B" (depending on year) that aligns up with outer edge of head when TDC No1 firing. in this position the injector pump if common rail has dot on gear that aligns to casting mark on pump near where shaft for gear comes out of pump (can only see when pump is removed) white texta mark the tooth with the dot and fit pump while all other marks previuosly mentioned are still in correct position, in side of bell housing there should be an inspection nut or plastic bolted tear drop cover to remove close to chassis rail look inside with mirror and torch and white texta marked tooth should be in middle of this inspection hole to confirm its not a tooth out.
if you know where the timing marks are supposed to be the use the old method of cam/crank timing to check and adjust to where the marks will be. Remove no 1 injector and turn the engine over until no 1 piston is coming up on injection stop when you reach TDC. mark on flywheel of harmonic balancer. If there is valve clearance ot both rockers turn the engine another 180 degrees and bring the piston to TDC again. watch the rockers and if you turn back a few degrees or turn forward a few degrees you will see ( in the forward direction) the exhaust valve closing and at the same time the inlet valve will be opening. This is known as valve rock. As you move the piston bacvk and forward over TDC you will see the valve movement. set on TDC and check the timing marks with the positions indicated. Remove and reposition the cam shaft gear to achieve the correct mark alignment or pull the cam shaft out just enough to realign the teeth to the mark. At the most you will be about 1 tooth out. The pump timing will be out 180 degrees as you are setting the valve timing on the induction stroke and you will need to turn the engine 180 degrees to compression stroke for the pump timing marks to line up. the injection mark on the flywheel is what you are looking for and when it is at the correct number of degrees as indicated by injection / lightning flash sign then the marks for the pump should be just about lined up
Most engines are required to be a TDC or Top Dead Center and then align the timing mark on the injector pump with the housing or mounting surface mark. I would obtain a specific manual for your engine...just to make sure. Best Wishes.
These things are easy to time. Just line up the scribe mark on the pump to the scribe mark on the timing cover and that's it. The pump only bolts to to the drive gear one way because of a dowel. One tip if your not already aware, leave the injector lines attached to the pump for removal and install, it will make life easier.
