Hey all. Having a few issues with my gc8. I’ve changed the ECU to an Apexi fc.( i also switched back to the original and still the same issue) The car won’t start, the fuel pump won’t prime either.. just to add to it, my dash no longer works, so I’m not sure if it’s a fuse causing that part.
i tested the fuel pump by bypassing it and it primed.
prior to this I had a MAF issue( has been replaced )
really don’t know where to start.. any help would be highly appreciated 🙌🏻

 

Check the MAF is good a dodgy MAF with an Apexi causes all sorts of grief.

 

thanks for the reply! Will do, if the wiring is fine( fingers crossed ) any other potential causes?
im not sure if this is correct but the pins don’t need to be changed on an apexi for a JDM ?

 

They come set up for JDM it's only the UK loom you change.

 

if the dash fails to illuminate then suggests you have an alarm / main fuse type issue presuming battery charge & connections are all good?

 

had a look at the MAF and the wiring is all good. Had a look under the dash, may have found the issue…
