Did you fill the new secondary fuel filter with fuel? Your engine will self-prime eventually but pre-filling the filter makes the process go much faster. There are meany threads on this subject here, use the search function.

uh, if you put on dry filters, its' gonna be a lonnnnnnnnng time before you will be able to start the car. it may even cause problems with the IP.
I'd pull the spin on filter, and fill it with fresh diesel or Diesel purge/power service, etc. and then leave the top bolt a tad loose, and crank again. when fuel spurts out the bolt, tighten it down, and then hold the accelerator to the floor, and crank your starter until it fires.

when i change the fuel filter i use WD 40 to get the engine started. I spray it into the air filter housing and at the same time have someone else crank the motor.

wouldnt wd40 compression ignite before TDC and potentially bend a rod?
Whenever I replace the spin on's I always fill them with ATF or motor oil or veggie oil from the kitchen

The more I think about it though I wonder if its really an issue. Lets say it does compression ignite before TDC, and the piston compresses it further, straining the rod. Is this force even remotely comparable to the force being exerted on the rods during WOT? There was a discussion on here about ether damaging prechambers when used on an IDI engine, but ethers a completely different animal
