I think there must be a check valve built into the 3 port djet pump
I believe mine is not working (Hard starting symptoms) Has anyone pulled theirs apart? Pictures or a thread? I'm also wondering if adding an in line check valve would work? |

Definitely check the pressure. You're only speculating until you see what the pressure actually does.
You might also want to check that the four-pin connector on the relay board is fully seated. One of the pins there carries the starting signal to the ECU, which in part uses it to tell the fuel pump to run. --DD |
