just a thought have you checked all vac pipes and replaced your inlet manifold gasket. sucking to much air wont be making life any easier

Check the inside of your distributor cap and look at the carbon brush. It should be spring loaded out, and you should be able to move it freely in and out. If it is stuck in, or damaged, then you will get a week or no spark.
Also check the output of the coil. You can still get a spark but it could be so week that the fuel will literally put it out.
Then check to see if your fuel pump is working. If not, check the fuel pump relay as these have been known to fail for a pass time.
You could also check your HT lead from the coil to the distributor cap. It may have deteriorated internally.
The list could go on and on, but these are simple checks you can do before going too deep and out of your depth.

There are no marks for the Cam sprockets?! If you look from the pulley side you will see the camshaft sprockets and there should be two dots pointing each other at TDC?

How can someone do cam to cam timing without this!

Not very clear, but aren't these the timing marks:

they should be on the inside too

Yep, on the inside... Heres a pic of mine:

If the two cams are correctly aligned between each other (which is most likely since it run before and the chain will very unlikly "slip").
However the main rubber cam-belt can slip if it is too loose and the engine has been reved hard. One notch out can make the engine behave very strange on idling and potentially bend valves at high-revs.
