Bike won't start

[Alkali Fatahu]

For sometime now I have been having a tough time starting my bike. If I push the starter button, the engine cranks but will not start. The fuel pump primes normally upon turning the ignition key on and no fault code is displayed.

I initially suspect the fuel pump, injectors and spark plugs. I took the pump out and tested it and it proved okay. I examined the pump housing and there was nothing to show it was clogged.
I changed the spark plugs and also cleaned the injectors and fuel line thoroughly. The still cranks but won't start.
One thing that preceded this was ticking noise. The bike did make ticking any time it was started. This noise lasted a few days after which the won't start. Please, I need help.

Year bike, immobilizer, mileage?

Have you tried cranking with the throttle wide open? What is the condition of the battery after all of this cranking? A weak battery will not start the bike - even though it's cranking over. A shot of starting fluid into the throttle bodies will tell you if your problem is fuel related or not.

2005! I have disconnected the dashboardI

I did that and I guess the result was what made me suspect it could be the injectors, fuel pump or fuel line. But all of these proved okay. I will do that again and get back to you.

2005! I have disconnected the dashboard for more tha 3 years now. But I think the mileage could be between 45k and 50k.

As noted, spritz some fuel or starting fluid down the TBs and see if she kicks.

If not, pull a spark plug lead, spark plug and check for spark.

You can check for compression if you can access it but my $'s on a fueling issue.

I'm curious, why is the instrument cluster disconnected? Is there another/earlier problem with the bike that could be contributing to the non-starting issue?

How do you know there are no error codes without the instrument cluster?

Currently, it is connected and there are no error codes. I like the bike extremely naked hence the disconnection. The dashboard is among a number of non essential stuff I have taken off the bike.

I have connected it back.

Did you spritz fuel down the TB's?

Any updates?

I just did that and the bike started but died soon afterwards. I did that two times and what I realized was that any time I tried opening the throttle it tried to die immediately.

Then you have fueling issues as in lack of..

Absolutely! I have read on the symptoms of a failing fuel pump and come to the conclusion that it is the fuel pump.
The pump works but I think it does not deliver fuel at the right pressure. I want to get a new pump.

I think there are a few steps you can take prior to buying parts. If you hear the pump priming, it is likely making (or trying to make) the correct pressure. There is a filter in the fuel pump assembly. I suggest removing the pump assembly and checking the filter. It is not uncommon for this filter to clog and cause the bike not to start.

I have inspected the filter and it is fine. Meanwhile, I bought a new pump and fixed it and still the won't start.

Is the pump priming up (for a sec or two) upon key ON?

It primes up to two seconds if not more

Pull the injectors with the fuel rail and turn on key. Fuel should spray out (obviously a major FIRE HAZARD) if it does work/spray. Do so safely...

If it does, you'll need to check fuel pressure while assembled.

We're trying to determine if the rail/injectors are clean, it's possible the injectors are NOT opening-IE electrical issue..
