I’m trying to get my father’s old Gen 5 up and running. He parked it in the garage 5 years ago and hadn’t touched it since.
I replaced the battery immediately so assume all of these tests were done with a fully charged battery. All fuses were in good condition.
The first thing I did was remove the PAIR system because it was so hard to work around.
I found that the residual gas left in the tank rusted the internal fuel pump/filter and some of the tank. So I cleaned that out, resealed it, replaced the fuel pump with an after market QFS oem replacement. When the fuel pump still wouldn’t prime I traced the problem to the fuel shutoff relay. I ordered a replacement on Amazon (which turned out to not be the model I ordered) so while I wait for the new OEM one to come, I bypassed the relay which now allows the fuel pump to prime. The problem is it doesn’t stop priming. Is this related to the fuel shutoff relay or is it a pressure sensor? Any thoughts?
Even with the fuel pump going, I cannot get the engine to start. Spark plugs look fine, engine is turning over. Oxygen is fine. The next thing I’m going to do will be to disassemble and clean the fuel injection assembly. And hopefully it is just clogged injectors.
Any help would be appreciated, especially around the relays - I’m used to working on track bikes, I’m not used to all of the sensors and relays on this bike.
