unexpected indeed, well there is a check you can do on the crank shaft sensor.
No need to remove engine cover but locate the red connector with white and yellow wires under the right hand side cover near the air filter.
The white wire is connected to ground inside the ecu.
with the connector connected use a straightened paper clip to probe the yellow wire through the little rubber seal around the yellow wire, push it all the way in until contact is made and the meter indicates a value of ca.500 ohms.
With the engine and ignition off measure between the yellow wire and chassis ground, there should be close to 500 ohm resistance.
This is the "reluctor"coil, this coil times the spark and injectors, when the engine is running it produces 7 volts ac for the ecu.
So with engine cranking it should produce a little ac voltage like 1 volt or so i guess.
With the ignition switched on but engine off the yellow wire has 0,3 volts DC with respect to ground supplied from the ecu.
Check if the connections are in good shape and not corroded.
here is what the sensor looks like;
and;
And here is how it works;
I don't think that this part is broken but at this stage it needs to be eliminated as a possibility.
Hope that helps.
Just had an idea; are you sure you re-connected the ignition coil wires correctly when checking the valve clearance? they are a bit awkward to get to.
