The compression numbers look decent. Car should start easy with 100% WVO down to about 35-40F-ish. It may not stay on well but it should start. 80/20 mix should start and stay on without any problem.

Try to take the WVO out of the equation by hooking up a bottle diesel under the hood. Purge the WVO with engine running and then leave it overnight. If it is still hard to start then it is something to do with car.

Good luck.
