Run the car for 30min and then lift the fuel rails with the injectors, prime the pump on and watch the ends of the injectors for weeping fuel or dripping. Very common issue with the age of the cars, especially true for the older VN-VR big body injectors, they really sucked for this problem. Also happens when you get the injectors serviced, they start leaking.

The leaking floods the engine and makes it take ages to start. Also check the vac reference hose for the fuel reg. Just yesterday I found that to be the problem in my nephews new engine and why it was flooding and hydrolocking. Fuel was pissing out of the vac line and into the manifold.


Yes that sounds good, I will get to that. This on my VS v6.

Oh, well that's going to be an issue. You can't lift the rails without lifting the plenum off on ecotec.

Well you are going to have to do it to know for sure. Is your VS the big grey tops or the small green injectors?

I have the green injectors in there now. It originally had the metal bodied ones, similar to VR ones from memory.
I will get around to pulling the plenum off.

Remember to do this when the engine and injectors are still hot as that is the only time I found them to leak.

That’s wrong, it can be done, I’ve done it plenty of times…

I'm having the long cranking first thing in the morning, cold engine. And if the car sits for an hour or so or longer I think.

I'm curious, how is it done with out lifting the plenum? Unbolting the fuel rail bolts that hold it to the plenum body?

I would also like to know, the fuel rail being one solid piece with the plenum keeping it down, I can't see how you would be able to move or lift it without the plenum moving out of the way.
