Default Fuel Pump problems?


Trying to get an idea on the likelyhood of what I am going to have to replace this time.[/align][/align]Have a 2005 FLHRCI Road King Classic with 36,000 + miles. Went to start the bike this morning and the typical key light and then engine light did not happen. Just the key light came on and then went off. Did not hear the fuel pump cycle. Bike would crank but not start. No problems starting yesterday or any other day in the past. Did replace fuel filter at 18,000 miles when doing my rebuild of the valve seals, pistons and cams. Did not replace the internal hose.[/align][/align]Since I was on my way to work I couldn't check anything.[/align][/align]So is the internal tank hose cracked, fuel pump dead or just the fuse? What are my odds?[/align][/align]Thanks,[/align]Bill[/align]

Sounds like the fuel pump relay.......
You need to verify power up to the pump.

the check engine light is not for the fuel pump although it seems to cycle that way. the light is checking the crankshaft position sensor mainly and other sensors for EFI.
.....I would check the fuse first...under the right side cover by the ecm.....the fuel pump fuse is not located with the rest of the fuses which are under the left side cover. With No check engine light I would check for other fuse outages.

lastly the fuel pump would at least turn on with a cracked broken hose....it stops because the pressure regulator tells it enough already when theprescribed pressure is acheived.

I totally forgot about the fuel pump relay. Thanks for reminding me.

So if the crank position sensor went out it would crank but not start up the fuel pump?

I should have thought about the cracked hose a little more. But was a little upset when I was typing this.

NO...what i was telling you is that the check engine light has nothing to do with the fuel pump.
And yes, if the CKS went out the bike would crank but not start.....However, the check engine light would be locked ON idicating a sensor problem.

And to clarify.....the fuel pump would run even if the hose was cracked and should not turn off.....it is just spewing fuel inside the tank and never allowed to build any pressure that the regulator would then shut down and maintain.

Okay so I get home and hook up the laptop so I can read codes on the DTT. No codes. The key light comes on and then the engine light comes on and then the key light and then the engine light just like it always does before I start it. So I think I'll try cranking it over again to see if it throws a code while viewing the chart. Well, the stupid thing starts. So I let it run until the engine is warm. No codes. Something weird is going on and I haven't a clue as to what it is. Anyone have any ideas?

Hey Mike
Welcome aboard. When you jump on someone else's thread with a problem you're having it's called "hi-jacking"......especially a thread 6 yrs old!
This forum is awesome and a lot of smart people are here waiting to help. That being said I would repost your problem as a "New Post". You'll likely get some answers when you post your own new question.
