Running on the bench?  Are you sure pin D10 is grounded?

Got a scope, good.  Take the ECM cover off and take a look at the signal 
on the gate of the output driver.  The one with the big hunk of metal
attached to it.  If you have a signal, things are good up to there.
Missing ground, burnt out driver?  There is only one driver in that
ECM.
