Hello Everyone! Thank you for reading.
My car usually cold starts no problem, and was warm starting perfectly. Back in 2010, the previous owner purchased a new fuel pump, and accumulator kit from DMC in Garden Grove (love those guys) and the cars been great until about a month ago. I'd drive it somewhere, park for an hour. When I'd get in, turn the key, the car would instantly fire up and die. Then I'd run the starter and run the starter and run the starter like the car had no spark. Checked my grounds. Found a loose ground under the ballast resisters and one on the frame rail. Still issues after tightening. Cleaned up the connections on the ballast resisters. Finally decided to get in and check the fuel pressure. I'm losing fuel pressure after the car is turned off.
After hooking up a fuel pressure gauge, I found the rest pressure drops to 0 from about 3.75 bar within 4 minutes. The shop that is helping me specializes in the Bosch K Jetronic system which is really cool. It's nice to have someone looking over my shoulder who seems to know the system pretty well as I'm just learning it as I go along.
In September of 2010 the car had a new fuel pump and accumulator installed along with a whole o-ring fuel kit sold from DMC garden grove. Everything I'm reading says my accumulator is no good, but it should be new-ish still right? Could my accumulator be bad after only 4-5 years and less than 7000 miles?

Looking at the my previous invoice I mentioned above, I wanted to make sure I didn't have an older style fuel pump as mentioned in the website. I believe my fuel pump is a newer style. The shop thinks that the fuel pressure is being leaked into the cylinders causing a flooding issue. or instead of it leaking into the cylinders, could it be losing pressure through the o-ring the site above mentions at the end? The shop seems to think the system pressure regulator o-ring is the culprit. They also want to pull my injectors to inspect.
What would you do? What do you think it is?
Thank you!
