Rb20det Into R31 Wiring Problem

[shaunmlawry]

Hi guys

Just after exactly what is needed to be wired up for my Rb20det to run in my 87 silo.

I have tried to wire it up from another forums instructions but can't get it to kick over. There is no injector pulse.

Any pictures of the wiring would also be greatly appreciated.

It's just frusterating me, it's there but i can't drive it

Thanks guys

The first thing you want to check is that the CAS, injectors, coils and ecu are getting power.

You should be able to hear the eccs and ignition relay flicking in and out when you turn the key to ignition and back off. The ecu should also be lighting up the red LED on the botton edge. If you cant see the light or hear the relays then you need to re trace the power feeds.

All wired up now.

Thanks anyway.

But i am having difficulty starting it.

I am getting fuel to the rail and injector pulse.

I am also getting spark.

But there is no fuel getting to the spark plugs

Any idea?

ive seen seized injectors on these things before, especially if its been a long term build.. how long has the engine been sitting?? did you get the fuel lines on the right way?

Yeh stupid me, fuel was on the wrong lines.

Took it out for a test drive today and the thing over heated on me

Anyone know how i can get the temperature gauge to work?

The temp gauge signal is just a single wire plug in the inlet manifold casting just above the thermostat at the front. You need to wire that directly to your gauge. It would have been in the original under dash plugs on the r31 dash loom and in the r32 engine loom
