I just got my '02 954 running again. It had a bad fuel pump, i replaced it and it cranked right up. I let it warm up to about 155 degrees and decided to mess with the idle range I put it to about 1000 to 1200 range. I let it sit in the garage for about two days and tried cranking it up again it would turn over for a quick second or two and shutoff. I think the problem would be that I changed the idle range so it has a hard time turning on. I don't really know if theres anyone that can help please. thanks!

Have you tried turning the idle adjuster up?

I turned it all the way to the left which is really low or no idle at all and rotated it about 3 or 4 times to the right, still doesn't turn on. I've tried making it higher and still nothing. Every time I turn on the bike it just keeps on pumping fuel and after about 3 times of me turning it on i just smell a bunch of gas from the throttle bodies

Have you checked the vacuum line to the fuel pressure regulator?

like clean it out? everything else is connected. a buddy of mine swung through to look at the bike and he said he did the same thing with his bike. theres a screw in the middle that connects the throttle line to the throttle body and i should tighten it a little to see if it makes a difference. please let me know if you've ever done anything like this.

Make sure the vacuum line is not sucking fuel.

Do you mean the idle adjuster under the left frame rail?
Or the throttle cable adjuster?

what would i need to do if it did suck in fuel? the throttle cable adjuster. its in between the throttle bodies and its just a small flat head screw looks like.

You would buy a new fuel pressure regulator.
I think you must be referring to the throttle linkage synchronising screws in the centre of the throttle bodies - they do not adjust the idle speed.

okay were you talking about the vacuum from the airbox? just a bit confused. anyways the hose were in the wrong inserts when i got the bike and since I've changed the fuel pump they are now in their original inserts. it definitely would be the problem if the hoses were in the wrong place and just priming fuel into somewhere it doesn't need to be.

There are no vacuum lines from or to the airbox.
Vacuum comes from the intake ports.
The vacuum line to the fuel pressure regulator on the left end of the fuel rail.
