2004 1500 Nomad fi losing power or dying

[ibcruiser]

Hey Team, I have an interesting issue on my 04 Nomad...Recently I've been experiencing a "sputter" when I down shirt and throttle up on an incline (Hill). Today it went from a “sputter” to blinking “Fi” lights and engine dying when I throttled up. I barely limped home... :-[ If I wound-her-up around 3K it wound stay running. When I throttled down or down shifted and gave it the gas I would get an “Fi” warning light at low rang of the throttle. My first foray into the Fuel Area of my Nomad… I thought maybe a fuel filter til I discovered there in not one. (Part of Fuel Pump?) Maybe a fuel pump. At 500 bucks for a new pump I want to be sure. Anybody out there on the team have similar issue? What fixed it? Thanks ahead of time for any thoughts… IBCRUISER :)

Im not sure about the FI light, that could be one of many things. But it wouldn't hurt to clean the throttle body good with a toothbrush and carb cleaner, and try some Seafoam in the tank as well. And are the plugs good?

Is it stock? If not, what mods?

My thoughts were the same as Ringadingh. Also if it just started doing this could it possibly be bad fuel? Check your air cleaner element. Could even be a short in a wire. How many miles on your bike?

It may also be a short in the wiring harness at the top of the rear cylinder on the LH side.

ib, it could possibly be a fuel flow problem but I doubt it. In a FI bike the fuel flow/pressure is not effected by engine RPM. It is a constant speed electric pump that is cycled on and off by a fuel pressure regulator. The regulator is between the pump and the filter. If your filter was pluged you would not get a FI light because the regulator would see a normal funtioning pump and pressure. And higher RPM would require more fuel so a partially pluged filter supports idle but engine starves and dies at higher speed.
If your problem is your pump failing then the regulator would see low pressure and give a warning light but it is a on/off pump and so is the regulator so I'd be suspicious of that diagnosis because the light is intermitant and flickering plus the "it's better at higher RPM" is contrary to a fuel problem.
It sounds electrical to me. I'd check you conections at the battery, then the ones at the ignition switch and then I would start looking at wiring harness's.
But remember the FI light is really 3 indicators: engine temp, fuel press & oil press. Make sure your indicator is not one of the other conditions before you invest time on anything.

had similar experience on my 2004... check your battery connections. ground on my had worked lose.

WOW I am impressed with the body of info shared... Thanks Team... Sounds like I have my work cut out for me... Will look at electrical to filter to a general tune for starters. I will share my findings team.. Thanks again ALL for you thoughts...
IB just working on the ride and not cruising for now.... :) IBcruising soon...

I had a similar problem when I bought my bike. Any time I would give it gas it would fall apart and would sometimes die. I couldn't ride it anywhere past 1/4 throttle. I tore through everything I could think of. I had just gotten done putting the bike back together after painting it so that had me looking all around the tank for the issue. I ended up pulling the fuel injectors and found a piece of the o-ring had broken off and partially blocked the injector. I never even touched the injectors while repainting the bike so, it took me a bit to find it.
Ran like a dream after:)
