Need help!!!

[bmoha7321]

I have a build blog and a build thread going on this; I am not getting any responses and I'm running out of time. I'm losing my storage and need to get this thing running pronto.
97 GSX AWD shell. 95 EPROM ECU. 97 GSX AWD harness. 96 motor. I have spark. I have full. I have compression. I was told I had to resplice and extend the cas from the flywheel side of the motor to the timing belt side of the motor. There are two connectors there on the timing belt side. One is triangular and one is rectangular. The rectangular one is on top. Both of them have red blue black wires in them. Which is which?

Red = positive
Black = ground
Blue = signal to ECU
Rectangle = Cam Angle Sensor
Triangle = Crank Position Sensor

Hmmm... I spliced and extended the plug over on the flywheel side of the motor with the red, blue and black wires to the rectangular connector at the timing belt side of the motor. I think that's right. And I plugged the triangular connector into the triangular connector. I'm feelin kinda strumped

Continuity check to the ECU harness?
2G Turbo ECU Pinouts

ok... I added that to my Iphone bookmarks... so to really make myself look bad how do I test this exactly?
Maybe I damaged my eprom ecu? I have a presumably good 97 ecu sitting there... Maybe I can pop that in and give it a whirl? I know then it changes the firing order; to what I don't know.

Ohmmeter or noid light, one probe on the engine bay connector the other through the window under the dash to the ECU harness, just check pins 88 and 89 against those sensor harnesses.

ok heading back out to work on it some more!

it started!!! Of all the weird things; the motor was 97-99 firing order. This is the way it has always been. I've never changed it. I changed it to 95-96 firing order and it fired right up!

Would not have been able to do this without this website and the help I've gotten from it's members.

Glad to hear it's running now.

the motor was 97-99 firing order. This is the way it has always been. I've never changed it. I changed it to 95-96 firing order and it fired right up!

It's not the engine persay, but whether or not the ECU and CAS decide to play nice with each other.

 

[bmoha7321]

When extending the cas wiring to timing belt side of the motor red should be spliced to blue & blue to red. Black stays spliced to black.

 

[delta448]

Never heard that before. Is that what you did?

Maybe the 2Gb harness has different wiring?
I would have thought it should've been on 95-96 injector/plug setup since you have a 96 CAS and 95 ECU.

 

[bmoha7321]

The 96 motor was using 97-99 firing order. Always has. I've never rearranged the spark plug firing order on that motor. All I did was change the firing order to 95-96 and it fired right up
