1. When you installed the timing chain, did you align the marks on the crank sprocket with the cam sprocket? (Most Have Dots On Both)
2. If you did, then you now need to locate TDC by turning the crank by hand (pull all the plugs to make it easy) and feel for the compression to build as you turn the crank by sticking your finger in the #1 spark plug hole..
3. You may also want to remove the valve cover on that cylinder head so that you can watch your intake and exhaust valves rocker arms to help guide you.
4. The intake will be open on the down stroke of the compression cycle and will be closed closed on the upstroke.
NOTE: Remember it takes two complete rotations to complete one full cycle since this is a 4 stroke engine.
5. If the exhaust valve opens, then you are on the exhaust stroke so you need to keep turning and watch what the rocker arms are doing because it will really help.
6. Keep turning it by hand until you are on on the compression side of the stroke and you'll feel the pressure build as the piston comes back up to TDC.
7. It should now have pushed your finger out of the #1 spark plug hole while you were turning it.
8. Watch the timing mark on the balancer and stop when your are at ZERO degrees on the pointer/indicator.
9. Reinstall the distributor and you may have to turn the oil pump shaft a little in order to align it with the distributor.
10. It will keep the distributor from seating all the way if you don't get the bottom of the distributor gear aligned with the oil pump drive shaft.
NOTE: You may have to play with it a while to get the rotor aligned with the #1 spark plug terminal, oil pump shaft and distributor in the correct orientation.
