2G Euro Eclipse 4g63 NA, swap 4g63t RVR

[john09]

Hi !
I'm French so sorry for my English, I made my best to be readable.

I have an EUDM 1997 Eclipse with an 4G63 N/A 150hp (Not an 420A)

I bought a 4G63T on eBay. It come from a RVR I thinks because it has an the top mount IC, can someone confirm?

I just put the engine and swap the ECU. I keep my N/A wiring because my N/A wiring is really close. The engine won't start, the fuel pump don't run
Have you any idea? Immobilizer? Faulty ground?

To check, I mod the wiring to switch on the pump on with ignition, engine still not start.

On my N/A engine the CAS is on the Intake Camshaft Pulley and on the turbo its on the end of the camshaft.

With the CAS plugged, engine don't start, the starter turn, but nothing
With the CAS not plugged, engine start good but not idling and turn off with check engine light.

Spark plug removed, the spark works, and fuel injectors open (I try with fuel rail removed).
But how to check the synchro between the spark and injectors ?

I have seen on web some mod for switch the injectors order, do i have to do this ?

Have you any other way to search ?

Thanks a lot all.

I think you need to add few wires to make it work? because there is a knock sensor in gst+ maf is different bov recycle, i dont know what else is different.

This is direct copy paste from internet.



1. The extra wire for the turbo MAF that your NT harness doesn't have. You will have to cut the existing NT MAF plug, wire in the turbo one, and manually run this extra wire from the ECU to the new MAF plug.

2. Knock sensor wire. The NT does not have a knock sensor, it would be your best interest to buy a new one and wire this in. It's simple. Threads into block, one wire is ground, the other goes to the ECU.

This is the easy way to do it. The harder way would be to source a complete turbo harness, take your NT harness out and replace it with the turbo one.

Pin swapped story maybe, on ECU or CAS connector ?

Swap plug wires around? Two dif firing orders right?

Test the plug wire swap : 1&4 with 2&3
Project Zero

thank you for everything, the engine is running,
So much invert coil swap 3214 4123 Original
also with inversion of the injectors
I will gather the mods that I can do for the swap
and I would put it later

thank you again

Thanks for feedback, but i'm still curious about injectors wire swap

Many thanks also to jared98gst

 

[john09]

thank you so much jared has 98 gst
you think I should not have reversed the injectors?

 

[john09]

so my engine is running very well now, I would get help because my wastegate has the acceleration does not work, is that it can come from the solenoid?
the pobleme c I have the schematic for the shield with the colors, but since I have a rvr engine is that it can be different?
if anyone can help me it will be really nice because I do not know what to do, thank you
