We were glad to find your channel and your fuel system videos on the 924. Currently putting my son’s 924 back on the road for the first time since 2009, and we are going through the entire fuel system.
Hi Brent, thanks for the comment and support. Fantastic to hear you have a 924 that you are bringing back to life. Let me know how you get on and please let me know if I can help out in any way. Best of luck 🚙💨👍
Is that the part that if the engine is cold it will cause a primer injection of fuel when starting but if it's warm it doesn't, thus causing the annoying no-start-when-warm problem? I think we bypassed that with a manual button wired in because my old 924 needed that extra primer injection even when it was warm. It was the wrong way to fix the problem but it worked. What is the reason they over engineered it to work that way anyway? Maybe that was a different temp sensor.
Hi Deth, so you are on the ball with that. Although there are a few adfitional bits that can add up to non cold and hot starting. But the fix you mention is one of the more common ones, mainly rigged to the 5th injector or cold start injector to get the engine fired manually as you say 👍
@Dethmeister No, this part regulates "control pressure" and is connected to metering head. It affects amount of fuel going to injectors depending on engine temperature. The thing you are talking about is called thermo-time switch and is bolted to back of the head and it activates 5th injector when starting the engine
@@maciejjarosz6011 you are right Maciej, but the fix we are talking about involves overriding this unit and using the 5 injector, cold start to fire the engine in cold and hot start scenarios regardless of coolant temp which the thermo switch uses 👍
