Ok- I'll risk starting another intermittant starting thread..  I've
searched, but haven't found anything that matches my symptoms.

91 Integra, 240,000 miles, driven less than five miles a day.  ECU
giving a 15 Ignition Output Signal code.

It starts most of the time, and if it does start, it will run all day
if needed- never stalls.

About once every three weeks, it won't start when I try it first thing
in the morning- even cool mornings.  It will turn over, fires,
sputters, then dies.  It will turn over after that, but won't fire. I
can hear the fuel pump humming for those first two or three seconds.

Just recently replaced plugs, wires, and o2 sensor to pass emissions
test.

About a year ago, replaced ignitor, coil, cap and rotor after sudden
death of the coil.

I've done the main relay re-soldering trick to solve the hot day
starts.

I do have the intermittant wiper/rear defrost problem which I know is
caused by the Integrated Control Unit, which I have not replaced.  Any
chance this could cause starting problems?

Thanks for any help.
