coolant flowing between iac and isc ?

[fixkick]

yes, i just listed all possible failures..
the voltmeter proves the pudding.

the starter can jam too.
in many ways. so can a solenoid jam if it rusts inside.
we can also bench test a starter
with battery and 2 walfart cable.s,
i do this all the time, not wanting to put a dead used starter in a car. a pain that.
i spin it up.
under load in car is best test but if bench test fails. all is a waste.
