You miss interpret me on the water pump- Look for spark again verify the color should be bright snapping blue spark-
How did you check the timing-visual or by using a timing lite following special procedures.
It tries to turn over but won't even start for 1 second. What is exactly do you meant by this. Is it cranking over but refuses to start or won't crank over at all.
An engine that has spark and fuel that w/n start with no serious vacuum leaks and cranks normally should start. The problem is compression. If it is an overhead cam engine with a rubber timing belt, a broken timing belt would be the most likely cause especially if the engine has a lot of miles on it. Most OEMs recommend replacing the OHC timing belt every 60,000 miles for preventative maintenance, but many belts are never changed. Eventually they break, and when they do the engine stops dead in its tracks. And in engines that lack sufficient valve-to-piston clearance as many import engines and some domestic engines do, it also causes extensive damage (bent valves and valvetrain components & sometimes cracked pistons).
Last, Why did you changed the water pump?
