HA! Don't get me started on those corn-foolios....Dood ya got a good insurance agent
I'm hopin that it's somethin as simple as that, man.Hey Pac what fuel pump are you using,,, is it the pump that came out of your rusted tank??? Are you sure you have 43psi fuel pressure at your fuel rail? You could have a lazy fuel pump. If you did you would still smell gas, you should check the basics, make sure all 4 cylinders are firering, and make sure that you have good fuel pressure.
Good lQQKn out Playa but I already instructed him how to check with measureing cup.Hey Pac what fuel pump are you using,,, is it the pump that came out of your rusted tank???

This is the tough one. I don't see any kinks...something else to check is your fuel lines i had one the other day a guy his bike wouldnt run brought it in and whenever you would lower the gas tank it would put a big kink in the line that you wasnt able to see, raise the gas tank up and it would run fine, rerouted the fuel line problem solved, just trying to bounce some ideas your way.
Whew...this is gonna be a good one. Dayum.Check all over for a vacum leaks. That's what it sounds like.
Do you have the plug wires on in the right order?
On the throttle bodies, are they seated with no gaps between them and the head? Make sure nothing is pinched.
Do the plugs look good?
Did you test the compression? If so, is all the cylinder PSI almost even?
Are all your lines and connectors hooked up in the right order?
How about the vacumm lines on the throttlebodies under the airbox? The ports that you hook a vacumm gauge up to, to sync the throttle blades. Make sure they're plugged or lined the way they need to be. Jinkster's "How to sync your throttle blades" how-to has a great description and pics on how these lines are supposed to run.
Maybe they're is still some gunk in the fuel lines. Remove it, use some carb cleaner and a air blower to clean it out. A few pieces of dirt in there can mess with the fuel system.
Also, check the fuel delivery throughout the fuel pump.
Is any of your ECU, throttle bodies or wiring of different years? An earlier ECU isn't friendly with any late model hardware. Make sure it's matched to the right year groups.
Was there ever any rags stuffed into the throttle bodies to keep dirt out of them that might of been sucked into the motor?(I've seen this first hand on a few cars)
I'd start with one area and work my way over everything that can interfere with the Busa's engine operation. Eliminate every possibility. Whatever is left over, no matter how remote or improbable has got to be the problem.
Pac, you'll beat this.
Will check the lines...and I think that the tip-over switch is in good order.Also, make sure the 2 vent tubes at the rear of the tank are not clogged and that your tip over switch is in working order.
now that would be F'D up...big time. I paid $40 for a set of shitty plugs? Oooooh that frickin burns!!!!!!just so you know you can get a bad set of plugs from the store, i have done it before in my drag boat
Yeah, the plug for your injector rail. You should be able to check your voltage there, right?Yah...I hope it's something as simple as that. I have a bad feelin about that multimeter...I'm all thumbs when it comes to electronics and wiring.Jesus.yep...going on two years and $6400.Yeesh! I hope you get this figured out. You've been rebuilding your bike, right?
I hope it is something as simple as a relay in the wiring harness, man. If it's a fuel delivery issue, there's a solution just around the corner. Testing with a damn multimeter can take forever though if you don't do it all day, every day for a living.
Perhaps there's an issue with the ECU wiring? The ECU controls the fuel delivery unless you've got a PC, right? To check the wiring you should be able to unplug the stock connectors under the tank and test with your volt meter, right?
Stock connectors under the tank? You mean like the diagnostic plug an stuff?
Pac, I believe facing forward from the rear of the bike, you need to plug the big hose outlet on the back of the right side of the airbox...not the left. Its closest to the idle adjustment screw. You mighta' unhooked/plugged the wrong hose......I believe I did. Cut new gaskets when I put on the block-offs.I don't mean to insult your abilities Busa but when you replaced the PAIR valve and block offs you did plug the vacuum line correct?no mods aside from the pair valve being removed and blocked off.Pac if I was you I would change things back to the last time it ran....then start your mods one by one till you find the thing that caused the problem. It does sound like a fuel issue of some kind tho. Hope this helpsNo idle...no start. She'll crank over and sometimes try to start, but she won't maintain idle. She cuts out and sputters.
More stuff
I'm about ready to give up.Please....help a brother out.
The external fuel filter was a neccessity, as the old one is already 7 years old. There aren't kinks in the fuel lines, though...and the lines are clear.
Gaaaah!!!
Just trying to help. Walk away from it for a while and let your thought process work it out.
You'll get it!
hogger...
Plugged the hose outlet on the left backside of the airbox, plugged the outlet on the #4 TB...
I got that correct, right?
