F1 flashing code and fuel pump fuse hot

I have a 2002 VFR800 with 50,000 miles. No issues in the last few years until the fuel pump fuse blew last summer. I replaced it with a new fuse and everything seemed okay although I always wonder why when a fuse blows. At the end of the summer I had a low battery and the dealership jumped the bike to get it started. After that the F1 code appeared. I put in a new battery but the F1 code continues when I start the bike up. I have not rode anywhere due to the code. I replaced the regulator/rectifier several years ago when the bike liked to cut the power and also added the VFRness harness. I have had no issues since then until the recent ones. Any thoughts or experience with these issues? I am thinking they are related but not sure where to start.
Thanks in advance for the help.

Step 1 would be to find out what fault code is triggering the FI light. There is a diagnostic procedure in the manual that causes the FI to flash out the code of long or short blinks, and a corresponding table in the manual to interpret that. Section 5-7.

 

Thank you....I will check this tonight and follow back up with what I find out.

 

Assume you might be meaning Main Fuse B 30amp blowing? There is no Fuel Pump fuse on a 6gen. If it is Main Fuse B 30amp, have a very close look at its fuse holder and its wiring along with its inline splice connector ALL can suffer badly from overheating high resistance joints. Main Fuse B feeds ALL your EFI stuff and bad connections for this fuse and its associated local wiring is a common fault, this alone could cause the fuse to blow.
Do you have any additional wiring and accessories added to the bike? If so make sure they are not wired in to the Main Fuse B circuit, this is a dedicated EFI power line that should never be messed with.
Seeing you can run the engine, measure your Charging Voltage directly across the battery, make sure you are seeing approx. 13.5v to 14.5v at idle and 5000rpm both cold and hot engine.

As Terry recommeded - Read the active Fi Fault Code and take it from there.

Good Luck.

 

First off, thank you Terry and Grum for the guidance.
I checked the F1 code last night and it looks like it is a code 27. It has two long blinks and then seven short blinks. Grum, thanks for the fuse correction. Yes, the fuse that is getting hot is the one under the seat. I will check the accessories and also the voltage in the next couple of days and follow back up. If there are any thoughts on why code 27 would trigger that would be appreciated. I see the cause in the manual but not sure what that actually means.

 

The VTEC spool valve is the solenoid that opens oil flow to trigger the VTEC system and allow your bike to run on all 16 valves above 7000 rpm or so. The fault would be an indication that there may be a loose or open connector, or wiring damage to that connector.

 

The ECM just provides a 12v positive on a single wire to energise the VTEC spool valve when four valve operating conditions are met, RPM and Engine up to temperature.
The ECM can only detect the impedance of the spool valve coil resistance, so either an open circuit coil or wire or connector, or a short within the valve or wiring, will flag a fault code of 27.
Suggest first test riding the bike getting it up to temp and rpm and verify vtec operation or not.
