Rb25Det Cold Starting Problems

[Rbvl]

Hi my rb25det cranks for about 12 seconds befor it starts when it is cold but the after starting it once when cold let it run for 5 seconds turn it off then start again it fires up strait away and fine the rest of the day. I have changed the plugs and plan on doing the leads. Another thing the afm is in the cold side of the intercooler pipe could this be affecting it? It's how it come when I bought it.

Might be AFM related but i doubt it.

Has it got Nistune / Other after market ECU?

I'm going to have a guess and say maybe its the Air regulator or the ECU (If factory) isn't seeing the cranking signal for fuel enrichment on start up.

It has a factory ecu it also will start if I give it some throttle while cranking so I'm thinking ecu might b stuffed

Try cleaning the cold start valve

Sounds like a fuel issue?
