I'm nearing completion of the swap and trying to get it to turn over.  Well i think i finally finished wiring the ecu.....the problem is the dash plug has a orange wire that is suppose to be the ignition to turn on the ecu.  I get no voltage from this wire when i turn the key.  All i'm looking for is a voltage on that wire and i'll be happy.  My engine/oil/and ohter light are on in my dash.  Then when i turn the key nothing absolutely nuth'n not even a relay click.  Could it be the nuetral switch from the tranny?  

i'm just look'n for a check list of what would make that wire not have power or what makes that wire have power.

What's up man.  Did you do your wiring correctly?  As far as I know, there are a few wires that have to be switched around by the battery and also some by where you are talking about.  If you go to sport compact car's website, they have a tech article that show's on how to wire the harness up.  Try checking that and get back.

Good Luck

yeah i have the pin lay out of the ecu.  The power plug for the harness and one other changed if i remember right.  The wiring harness is done correctly (came off a working sr in a 240).  Yeah i own that issue of sport compact car.  Pin 38 (if i remember correctly) is the ignition and there is another one for the ground.  This has to do with the stock internal of my 240sx i think.  i only trouble shooted if for an hour but i just figured it was stupid stuff like i found out i never pluged the clutch depression switch back in.  But i'm wondering if my car thinks it's in gear some how or a relay is completely dead (might have got water in the box).  There can't be too many reasons it wouldn't send a signal from.  It's only from the battery to the ECU that i'm concerned about.

thnx for the help
