449 no start after oil change and zip ty oil tank install

this is my first oil change on the TXC. so bare with me.. I also googled and searched this forums.

Ok.. after oil change and zip ty oil tank recirculation tank install. I went to start and it ran and bogged and died like it ran out of gas.

I had to disconnect all the relays and connectors to to the tank install.. thought the relays were a little hard to re-connect. double check all the connectors but they look good. no pulled wires, cant see any that I might have pinched...etc.. messed around and it tried to start but didn't.

Now it doesn't want to start at all.. starter turns well.

did the TPS reset as instructed on the forums.

thinking I pulled a wire or jack up the relay somehow..

anything else I need to be looking at.

going to check the relays tonite

Pretty confused right now on what I did any insite on the trouble shooting would help

thanks.

You're right to think fuel system- also check both of your petcocks.

Check on the ignition coil connections.
There are reports the earth wire on the left side of the head fracturing also.

Unconnect all connections you touched, examine for bent over pins, mis-aligned metal tabs in the connectors. If more than one relay is involved, make sure the correct relay is on the correct connection.

Anything yet? hmmm, ok- let's look at the weird stuff that would let the bike run and then act like it ran out of gas (it was running fine before, right?):

• you can see gas in the header tank, so- CAN you see gas in the header tank?
• is the header tank vented ok (pinched hose, no blockage etc)? it uses the main tank vent.
• is there a rag in the air filter intake (well, any obstruction anywhere in the intake system)?
• same for the exhaust?
• you confirmed the electrical connections, right? including the injector?
• seems to me that if you disconnect the injector end of the fuel hose and then pre-pressurized the FI (flash the starter, keyless right?).... you'd spray gas at 50psi out of a 8mm hose for 75' or more. sounds real, real dangerous- even if you were prepared for it (outdoors, fire extinguishers, fuel containers, kill button, extra person on a hose). OTOH, you'd confirm your fuel and FI system. I'm not really a FI guy, so don't listen to me.
• didja check the fuses ('specially the pump fuse)? ...and if one blew: why?

I'll add to this if I think of anything else in the "weird" catagory.

If you still can't figure it out, give me a call.

thanks for the feed back..
I checked everything and I believe I have a bad relay.. I tested with an ohm meter and when powered up one still shows an open circuit. I have a few on the way.
I believe the relays are the same from looking at the book.
bike ran before the tear down..

Yep I'm learning these efi dirt bikes sure do have a lot more wiring. and boy is it tight in there with hoses and wiring.. my thought maybe I yanked a wire when removing zip ties on the wiring harness going to the fuel pump. checked everything many times visually.. after I get the new relays if it doesn't' run then I'll check with mulit meter and see where the issue is.

The relays are the same, so you could temporarily swap the fan one into the fuel pump position to confirm your suspicion.

Fixed!!! yep it was the relay.. happy happy happy.! thanks for the feedback and help troubleshooting..
