Hi I'm new to forum and the tlr I'd appreciate some help

98 tl1000r

No electrical mods that I know of. I corrected the chec f1 alert and bike will try and start.
The problem I'm running into is once I turn the key on I hear the fuel pump relay click but the fuel pump won't prime. Now my friend who sold it to me said it ran fine when he ran it last but it's been sitting in his garage for 2 years. Could the fuel pump be seized or bad?

Check for voltage out of the fuel relay. If you have voltage, it may be time for a new pump.

Clutch switch?
Sidestand switch?
If you hear a click but no prime, it's usually something silly with the wiring/electrical connectors. Pumps do go out, but it's not real common...more common for the pump relay to take a crap.

If you haven't already, you might want to have a look over at TLZone or TLPlanet.
TONS of resources and knowledge over there.
TL's are finicky...you can never have too many friends with one of these things (I own a TLS).

Good Luck.

I followed I guys instructions and checked the voltage on the relay wires.

I have my constant 12
I have power at the one aftervu turn on the key
But the wire that is suppose to have power then drop for 3 seconds to trigger the relay has no power to begin with

So, that is either a relay issue or ECU issue. I don't have a schematic handy to know which, though. If you can find a schematic and post it, that would be really handy.

I just help a friend of mine last year in Okinawa with the same problem. What we found is there is a relay next to the battery box was bad and burned out. Once the new one was end it started up fine. Check all the relays to make sure they are good.

So I'm assuming just cuz a relay clicks doesn't mean it's good?

Well tracked the wire that is suppose to drop current for a few seconds back to the ecm and its corresponding pin and checked for power there and it too had no power, but to be sure and to eliminate everything else , u know the proper way to check a fuel pump? And thanx again guys

Exactly...the click you hear is the electromagnetic coil working.....but if the contacts are burned or shorted out that won't do a dang bit of good.

Best test is juice in juice out = good. Juice in no juice out = bad.

These are the exact things we thought as well. We check the fuel pump as well along with the stator. It all lead back to the relay at the battery box. I would start there first.

So your saying if the battery relay is bad then that would stop power from going through ecm to power the fuel pump? Cuz from what I hear its actually quite rare for a tls ecm to die

Signal comes from the key to the kill switch to the ECM to power the relay which powers the fuel pump. We really need a schematic here......

Service and Owner's Manuals are available for download at TLZone and/or TLPlanet, if you're a registered member.

"Steve's Homepage" is another great source of info. Might even have the diagrams available:

Don't forget to check the sidestand and clutch switches...sounds stupid, I know, but they have stranded many, many TL's...

My TLS ran like sh*t, until I discovered and corrected a loose sidestand switch.

Dig into the fuel pump as the very last resort. Total PITA to successfully re-seal the TLS/TLR fuel pump flange gasket. Quicker way to test the pump is jump it and see if it's spinning.

Do a search on this topic on either 'Zone or 'Planet, for hours of reading pleasure.
Seriously.
Just a simple Google search like "TLR fuel pump won't prime", etc. will get you in the door...

if it sat for two years im curious how many times it has been jump started.....id be checking relays like already posted and verifying the ecu is functioning as they are pretty fragile.

i had a 99 TLR they get their gremlins from time to time.

They also don't like half-dead batteries...weak batteries cause all sorts of weird, seemingly unrelated issues.
Is your battery healthy and fully charged?

Yes, it's a brand new battery, fully charged and checked. I wants to test the fuel pump but being new to bikes I'm not sure which wire to jump, there's 4, 2 with a coating over the contacts and 2 that are not. Is there a way to test my ecm?

Thanx guys for all your help, turns out the damn impeller in the fuel pump was stuck, pulled it gave it a couple knocks and it works.

Piece of advise....replace it before it leaves you stranded. Most likely this is due to rust and/or varnish inside the pump from it sitting.
