first time poster long time reader!
Okay I'm going to explain this the best i can .......
around 1 month ago, i started my car then it began to spit and sputter and die... threw a low fuel pressure code, the fuel pump wouldn't turn on to prime the system but 30 mins later the pump turned on primed then it started right up fine without issue.
Then last week the same thing happened again i let it sit for an hour then it started without issue.
This past weekend it began doing it every time i went to start the car (low fuel pressure pump not turning on to prime the system) and it became harder and harder to get it started until it wouldn't start anymore. The fuel pump would no longer turn on. Note when the car did start it worked flawlessly as i monitored everything with my hondata to see how the fuel system was working while driving. It appears to be the initial fuel pump prime is the issue as once the car starts it works fine.
So a 301km tow home (not covered by honda)and i tear into the car to try and figure this out. So what i have come up with is the following:
Relay is getting power and functioning (even replaced it to make sure)
Fuel pump fuse is okay (even replaced it to make sure)
Fuel pump does NOT have power at the pump connection on top of the tank
The fuel pump fuse does NOT have power
Hondata log shows with the ignition on the fuel pump duty is at 100%
So my question is there a module, sensor, regulator or anything in between the fuel pump relay (in the engine bay fuse box) and the fuel pump fuse (in the cabin)
