History I have rebuilt and swapped about a dozen EJ engines since 2004.

Currently have a 2008 NA impreza that has me stumped.

Bought with busted block last year. Replaced short block, but alas in February the bearings started to go.

Got another block from a 2001 Legacy. Of course my heads, manifold and crank. Also the 9mm oil pump with the crank sensor from the last iteration.

Issue. It won't start!!

It has fuel, it has air and I am triple checking the spark. I have voltage to the coil.

Thought it might be a ground issue.

But other than the usual, plus a few i added to the heads. It's grounded.

Did the timing over, just because, but no change.

Sometimes the `simplest answer is the right one, but it escapes me.

Where to next?

Put a spare plug on a wire and see if you have spark.

good spark, put a little gas in the intake.

Did you swap the timing gears over from the 2008 engine to the replacement 2001 engine? 

If not, that’s you’re issue I reckon.

Went back over every detail and found that there were two teeth missing from the crank sprocket.

Replaced and starts right up.

Will test drive tomorrow.
