1995 vw Cabrio with NO SPARK.......HELP!!!

I bought this CABRIO as a basket case. The car is beautiful except for the engine. All the engine parts were in the trunk when I bought it, except the block and head. I was told by the previous owner, that the timing belt broke,he had SOME guy put a new head on it and he did not replace the tensioner pully, the belt broke again and messed the new head up,,,thats when he gave up on it and sold the car to me. I removed the new head and had 4 valves put in it and reinstalled it and all components. I installed a new water pump,plugs, plug wires and several other things that were questionable. I filled the cooling system,changed the oil and filter and stupid me, expected the car to start. I does not. It spins good and pops like it wants to, but wont start. I rechecked all my timing marks and looked for anything not hooked up, but all looks good. I checked for spark at the plug wires and this is my problem. NO SPARK. My ecm relay is clicking, so I assume there is power to it. The middle wire on the coil plug,its black/red, is the signal from the ecm to the coil, and that has no power on it. Anybody have any suggestions on where to start looking? The cabrio is a 95 with auto trans. I'm thinking, maybe crank sensor,then again, I'm not sure. I have fuel to the engine, so the pump is working, just don't have any spark. Any help would be greatly appreciated. Tom

Hello, MMMMM A weak point in all automobiles is the replaceable key switch in the column. I wonder if this 13 yr old
has a lack of power from the key. Allan
