-this is the only thread i have found so far with the same issues but this was on a fc and once was a automatic. lemme know what you guys think

one interesting thing i was reading in one of the above threads is where hailers2 was talking about the ecu not seeing the start signal. now i did replace the harness that goes to the starter awhile back and i dont know why but that harness did not match up 100% as i had to run my own wire from the starter solenoid to the connecting harness for the starter signal. now i have not had any problems at all with this. but i wonder if possibly somehow my ecu isnt seeing the start signal
codes that are still present are...
23 Fuel thermosensor
28 Solenoid valve - EGR
30 Solenoid valve - split air bypass
38 Solenoid valve - accelerated warmup system and air supply valve
39 Solenoid valve - relief 2

grab the hand controller and go to the fuel screen, bump the injection up 10% and see if it fires.
oops nm, no power FC. check your thermosensor input voltage to the ECU as well as your TPS voltages.

one more bit of info... the drivers side fan does come on when the ignition is switched to the
on position. with that being said would that mean that something is telling the ecu that the car is warm therefore no injecting enough fuel??

Sounds like you are getting closer! That's awesome! I'm not 100% with these rx7s but most cooling systems have a "coolant fan switch" that is based off of water temps. Once the water temp reaches a certain temp the fans kick on. There's generally a relay as well for this, and that could be stuck or your fan switch failed. I'll have to look more into how this is setup in these cars.
so had a little time to work on it again today....only thing i have noticed is the pin 1C is always seeing 12v as if it is harwired. i dont feel that this is my cold start issue
ok so note to keep posting so much but i did just recheck some things and according to the ecu pinout on alldata... the fuel thermosensor needs to be tapped into pin 1u. i dont have mine tapped into that so hopefully thats causing some issues
ok so may have found something...doing pinout test and found 3E(coolant temperture sensor) reading 12v constant....this is only suppose to read about 2.5v at 68degrees
