Starter issues solved finally....but more probs???

[accel junky]

So I solved the starter problem. It was definitely that the positive terminal on the battery wasnt tight enough around the post.

Anyhow, now I tried to start the car and got it to cough and spit and combust and almost stay running, but couldn't. I could only get it to combust when I applied 50% to 75% throttle.

I tried this with Stock Ecu and Power FC (all appropriate settings selected).

The service manual says that if there is incomplete combustion and pressing the accelerator causes it to combust better then check the AAC.

Well I checked the AAC and didn't get the results the manual said for a good AAC. Turns out the AAC is not getting power from the ecu, and pin 4 on the ecu is not sending any voltage to the AAC.

My mulitmeter tests out fine. Ohms are zero'd out to begin with and for voltage I am showing the 12v coming from the battery to pin 58.

Just for kicks, I checked some more sensors. The throttle sensor does not test out to the results stated in the R33 manual (continuity), but the throttle valve sensor does test good.

I checked the FIDC and it also checked out bad (continuity and voltage)

Injectors are tested fine.

This was done on both the Stock ECU and the POWER FC (which works fine, displays on commmander and recognizes injector duties etc..)

The only conclusion I can come to is that my ECU harness is bad for some reason and that the sensors are bad too.

Anybody have any ideas, or do I need to start selling myself on the streets for some serious replacements?

Thanks,Daniel__________________

Check for leaky injector or way too rich condition, that why with more air it tryes to start.....
