>Get two good sized rocks and rough up their surfaces.
>Practice striking one rock worth the other at approximately 45 degrees.
>Douse your intended for area with gasoline (don't forget a healthy wrong of your clothes as well).
>Strike rocks at gasoline until the fire starts.

A shot of Chlorine Trifluoride will light 'em right up.

Striking anything hard on anything hard can generate a little spark through the laws of friction. It's not good enough to start a fire though. Flint will produce sparks when struck against iron because siliceous rocks hold an edge better then any other and you need a sharp surface in order to shave off thin enough iron filings to spontaneously combust in the presence of oxygen (this is why cutting through steel generates so much spark - iron filings being flung and ignited mid-air once they lose the surface oxide layer). You can use any source of local iron, like pyrite as the Ancient Greeks used and any source of edge, provided it's a good one. Flint and obsidian and quartz just happen to make the best edges found in nature when chipped. You could theoretically use other types of rocks if you were willing to resharpen over and over again when you break the edge. It's just pointless and needlessly making it more difficult for yourself when you could just learn some rockhounding skills like your caveman ancestors did.

Anyone tried using rocks as fuel for a fire?

yes, I've burnt coal before. And pyrite. And oil shale.

Make sure the fire is large before adding rocks from the bottom of a creek bed. It'll blow you away how awesome they are for fuel.

OPs wife, is that you?

The gear industry is trying to keep rock fires covered up so they can sell firestarters. Our ancestors knew all about this. Keep looking OP

If the rocks are from a riverbed and a bit wet they'll actually produce a but more explosive heat

You put the rocks in a circle around a small pit filled with sticks and kindling then you use your lighter to make a fire
