Sounds like you have spark and compression--it starts with a shot of starting fluid.

That means you don't have fuel going into the motor--or at least, not the right amount.

Check for disconnected wires. Easy way to cause a no-start. Ditto hoses. Check for broken, brittle, or cracked wires. And hoses.

Then check to see if you are geting any fuel at all--pull an injector or two and stick them into glass jars. Look while someone cranks the sarter to see if any fuel comes out, and what the spray pattern looks like.

Those are first steps...
