Retro Tech & Electronics | Yamaha VSTAR 1100 Fuel System Testing and Troubleshooting - From The Fuel Tank to the Carbs @retrotechandelectronics | Uploaded July 2020 | Updated October 2024, 18 hours ago.
Today we will be going through the complete troubleshooting of the fuel system of the VSTAR 1100, before paying a mechanic to do it. You might find you can isolate and repair the problem yourself. A link to a movie is provided with instructions for the removal of the rank and required items.
This test begins with the battery, ensuring proper function, without which, nothing electrical is expected to work properly. This is followed by a quick test of the fuel valve itself. Does it flow? DO YOU HAVE GAS? Happens more than you think.
Moving on, the side cover is removed to expose the pump, we can remove that cover and listen to hear if priming is attempted. The sound tells us much, A few tests based on this sound can allow us to see if there is a blockage or a faulty pump with good electrical flow. This includes removing the cover under the seat to expose the fuel filter for inspection and possible replacement.
If the pump wasn't making noise, other electrical components may be faulty too, we should start at the main fuse 30A under the seat, from there, the fuse box on the side has a 10A that should be checked, along with all of the others. With the fuses good a check for good starter operation should be done to rule out the kill switch or the side stand switch.
At this stage the ohm meter should be brought to the harness where the fuel pump is to measure the resistance of the pump motor, Finally, the fuel pump relay is removed from forward the carb area. This test is a bit tricky for some, as some folks may want to take this to a more experienced person or a shop for testing. This requires a separate 12v power source to energize the 12v relay with which the ohm meter measures the contact side of the relay.
The last piece of the circuit is the ignitor that can only be tested in a swap-out at a shop or dealership. A separate video link shows the tank re-installation. The only other issue could be an open wire in the system as a short would have blown a fuse.
