My trusty 07 DL650A seems to have a fuel pump issue, and I'd really appreciate the wiser minds here checking my logic before I spend big bucks on a new pump.
Symptoms: won't start. Starter cranks but engine won't fire. I do not hear the usual sound of the fuel pump energizing/ running. I have taken the following steps:
Fuse: checked with multimeter and even swapped it. It's good. The fuse block is getting 12v.
Relay: audible click when key is turned, clicks again after a few seconds. 12V on both sides of the relay (relay plug and 3-pin plug near the fuel pump) for a few seconds when I turn they key, then drops to near zero. I assume this is to "prime" the pump, and the voltage drops when it doesn't sense the engine is running?
If I'm correct so far, am I also correct in thinking the fuel pump is bad? I'll add that I bought the bike used, and the fuel pump has always been noisy, so perhaps I failed to recognize the significance of that.
I'd appreciate any thoughts. I'm very much an amateur at this!
