Rb not firing on number 6


Recommended Posts

Gidday folks

Have just swapped a31 cefiro from rb20 to rb25 s1 using the rb20 loom and ecu. All I done with the swap is change over the injector plugs and used all the rb20 sensors (cas afm coils etc) . I left unplugged the aacv, coldstart, oil pressure sensor, and vct. 

What I've tested

Test spark, has spark 

Test light in injector plug has pulse

Rotate cas by hand with one injector plugged in can here it clicking 

Swap coils

Swap spark plugs

Swap injector

Check for compression, has compression 

Check intake manifold gaskets they are good. 

No. 6 is not firing at all doesn't make a difference if coil or injector unpluged 

From here I am lost for what to check. Its like it loses spark as soon as the coil is bolted to the head, the timing is off for just that cylinder or the loom was pinched during the swap... I'm unsure any help is appreciated
