850R Won't Start

I have a 1996 850R with 118,000 miles and it won't start. It was running
fine until I stopped at a store. I came out and it started but ran very
roughly and at below 1000 RPM. It then won't start at all. I had to get it
towed home.

Here is what I have diagnosed thus far:

1) There is spark at the spark plugs.
2) The battery is fully charged.
3) The engine is turning over.

I also just happened to have a tune-up kit and changed the plugs, cap, etc.
I haven't changed the fuel filter yet but it was changed about 25,000 miles
ago.

It sounds like fuel is not getting to the cylinder. Any thoughts?

Thanks.

 

Can you tell if the fuel pump is running?

 

What's the method for doing that?

Thanks.

 

Update:

I bought a OBDII code reader and there are no codes.

 

Err your ears?! lol!

I bought a OBDII code reader and there are no codes.

Any blown fuses, or look for bad connections and check connecters are a
tight fit.

For those who care... I did some further debugging and determined it's the
fuel pump. I bought a fuel pump only for about $90, used the existing
housing, and it's running again.

 

Might be your fuel filter.

 

Or it might be fuel pump, is it working?
