VG30E Low fuel pressure
« on: 10:48:40 PM / 18-Aug-18 »
In my quest to get my SE back on the road, I've cleaned out the gas tank and replaced the fuel pump with one from a junked SE.  It's got a fresh fuel filter.

Currently it's a no-start.  I have spark, and I have pulse at the injectors.  I hooked up a pressure gauge between the fuel filter and the rail and it's steady at right around 30 psi.  I believe it should be at least 43 psi.

My next step is to swap out the fuel pressure regulator with the one from my extra engine and see if that makes a difference.

Thoughts?

Hope you get it going. My SE has been out of commission for months as a no start. I changed jobs and have had no time to deal with it yet. Last time this happened, I gave up and took it to a shop, they found three bad grounds. I will be searching for all the grounds soon.

Last weekend I swapped over the fuel injectors from my spare engine.  I'm working on getting the fuel and intake systems reassembled, but Florence has forced me to take a break.
