. Having just taken the car through an emissions inspection, I found my Hydrocarbon outputs a bit too close to the limits, so I felt a tune up was in order. I have replaced the spark plugs, wires, distributor cap and rotor, both fuel and air filters, some leaking fuel lines that I found in the process, PCV valve, and I changed the oil. Now, the car will not start. I have verified that I have spark from each of the spark plug wires, (By holding a connected spark plug against the valve cover with pliers and cranking the engine.) And the firing order is the same as when the old components were removed. (I made a diagram.) I do have fuel getting to the carburetor and all vacuum lines are connected where they should be. Compression should not be an issue, because the car ran before I did the tune up. I have checked everything that my Haynes manual has recommended me to try. The PCV valve fits into a socket on the block and a tube leads from a nipple on the PCV valve to the intake manifold. The old valve was dangling from the tube, and not fitted into the socket. I put the new one in correctly, however this should not affect the starting of the engine. I walked to a Honda Dealership and asked a mechanic if there were any other things I should check. (I do have fairly good mechanical knowledge and experience, but it's always good to ask the experts.) I have also tried replacing all the old parts that I removed, including the leaking fuel hoses. There is no way I could have installed the distributor cap or rotor 180 Degrees out of phase, as I have purposely tried to install it wrong. Ether starting spray will not work, nor will cranking with the throttle to the floor, with or without the choke propped open. I have let it sit for a few hours with the plugs out to allow any excess gas to evaporate. I am all out of ideas, as is my father, and several mechanic friends.

Three things you need for an engine to run, compression, spark at the right time, and the proper amount of fuel. Start with checking the compression and verify that the timing is right.
