The links don't mean much of anything as long as the cams are set right.
Are you certain that you're at TDC? This will be easy to do with the valve cover off. It'll look like you have it: Intake Cam is at 12 o’clock, Exhaust Cam is at 1 o’clock.
1) Crank your motor by hand to TDC (top dead center). Be sure that it is at TDC by putting a dipstick or other thin, straight object in the spark plug hole and waiting for it to pop up at the top and check your cam alignment.
2) After this, simply unbolt and pull out the distributor CAREFULLY (DONT STRIP THOSE TEETH!), and see where the rotor is positioned and set the rotor to cylinder 1. Mark it with a grease marker to make sure it isn’t spinning badly in the process.
3) Reinstall the distributor. It may take a few times, but don’t get frustrated about it, it will come out right. If it doesn’t work, crank the motor to TDC one more time and try again.
4) If that STILL doesn’t work, the distributor may be 180’d out. The simple way to fix this is to move plug wire 1 to plug wire 4 and vice versa. Just don’t forget that you did it!!!!!
There is also a ground on the back of the head or valve cover gasket that a lot of folks forget to hook up. Look for that, too.
If it still isn't working, go with the tired and true standby of diagnosing.
Air/Fuel/Spark
An engine needs air, fuel, and ignition to run.
Air- does the throttle open? Check for vacuum leaks while the engine is running.
Fuel- Confirm that you have it either by listening to the fuel pump prime with the key in the on position. If you hear that, confirm fuel delivery by pulling an injector and watching it run. You can also change the fuel filter if you haven't already. If you don't think you're getting fuel, try adding some through a vacuum line or using starting fluid sprayed into the throttle body. If it cranks right up, you have a fuel problem.
Spark- Test for spark by pulling out a plug wire boot and set it on top of the valve cover (away from other wires or anything flammable or electrical) and have someone crank the engine over. If you have spark, you should be able to literally see it arcing as it grounds out.
If you verify both fuel and spark, make sure you aren't getting TOO much fuel by pulling the fuel pump fuse and cranking for a while. If it starts up after a bit, you know you were flooding.
