I have a 2000 busa with 7,000 miles on it, 100% bone stock, never modified in any way. It was in storage for the last couple years and when I took it out, it wouldn't start. Battery was bad so I replaced that and continued to have problems getting it to start. Replaced the plugs, drained all fuel out and put fresh fuel in and the only way I could get it the engine to catch was spray some starting fluid into the air box. That would cause it to cough and catch for a second or two. At least that verified that I was getting spark in the cylinders.
Fuel pressure was low so I replaced the fuel pump and fuel filter as well as the fuel lines. I also removed and cleaned the injectors.
Still couldn't get it to start until I disconnected the air pressure sensor vacuum line. At that point, along with a few teaspoons of gas down the throttle bodies I could get the engine to start and run very poorly.
Checking fuel pressure with the new pump, it is only registering 15psi which is clearly too low and will cause the engine to barely run.
I'm sort of out of thoughts on what to look into next. Was hoping someone on this forum might have a suggestion or two.
Thanks,
Mike
