The pump should 'spool' up pressure as soon as you turn the key on. If you're not hearing it spool up (and typically shut off again after a few seconds), it's not working.

- February 02, 2017, 22:45:01 PMif the tank has corrosion, chances are the fuel pump gave up. They are cheap enough to replace[60 bucks] and reliable as hell under constant use. just not very well prone to sitting long term with old fuel. Easy to replace and peace of mind. http://www.highflowfuel.com/i-23443596-new-intank-efi-fuel-pump-vulcan-1500-drifter-vn1500-2001-2005

- February 01, 2017, 19:20:15 PMGreat looking drifter there!! I always said I love a 2-toned bike-especially a Drifter 
That looks a lot like Troll's bike, and several others, it's a great color combination.
Glad you got the starter thing sorted out. On the fuel pump, looks like (from the diagram) the ground comes from the ECU (BK/W wire) and the power comes from the fuel pump relay (DFI relay) (W/R wire). To test the fuel pump, you could jump a hot wire to the W/R wire at the relay. This should energize the fuel pump, and bypass everything else. However, it does assume the ECU is good, and the wiring from the relay and ECU to the fuel pump (and the plug under the tank, btw). Incidently the W/R wire at both fuel injectors and the idle control valves are all the same W/R wire. Another option (better perhaps) is to remove the tank (it's not that hard) and unplug the 4-plug plug going to the fuel pump in the tank. Jump wires from your jumper box to the plug going to the pump- +on the W/R and - on the B/W. This eliminates everything but the pump and wiring harness.
Hopefully Troll will be along shortly to admire his bike's long-lost sister, and maybe he'll have something easier to try.

- February 01, 2017, 16:34:24 PMso I got it turning over and I have at least some fire. but not matter what I do I do not smell gas. so I think the pump it frozen or one of the lines. from the look of the insides of the take there is a lot of corrosion.
My question this time, is there a easy way to check the fuel pump? the book talks about it and I could do it. I am checking the relay shortly. But I don't want to waste time tearing the tank off if there is a easy check.
thanks Gray

- February 01, 2017, 06:50:35 AMso got bored, and went and checked the clutch switch. Guess what the bike is now turning over. not starting yet but got it turning over next to check to try and get it started.
I think during the accident the wire got hit on the clutch switch. it is has a temp repair on it right now.
thanks Gray

- February 01, 2017, 06:35:55 AMthanks for the info. I have a few meters and will be checking what you suggested. I am gonna look closely at the clutch switch and everything connected to it. along with a bunch of other stuff that was connected. I will be working on it Thursday and will let you all know if I find something. thanks. Gray

- February 01, 2017, 01:54:14 AMAlso I have three drifters that sat for a bit and the clutch safety switch was always the issue. Turn key on Press starter button while jiggling the hell out of the clutch lever..that sometimes clears the issue. they get tarnished connections for some reason when sitting for a bit. But if your fuel pump isn't activating when you turn on the key..this isn't the issue.

- February 01, 2017, 01:44:49 AMThe answer to your Question about the ignition switch is that they have a security resistor built in. So replacing the ignition switch will not allow the bike to crank over or start. The yellow wire has to have a 100 ohm resistor wired inline to compensate for this. Any decent hardware store will have these.

Posted by greenbarn
- January 31, 2017, 21:37:52 PMIt is designed to start either with the clutch in, OR in neutral - either way. Here's the catch, though-- both of these switches rely on the same wire at the clutch switch - so if the wire connection is bad here, neither of the safety switches will ground, so the starter relay will not work. Looks like that wire is black, so if you ground the black wire at the clutch switch it bypasses the neutral switch and the clutch switch. This is the first place I would look - I've read about numerous problems here.
There is a "main fuse" located in the main starter relay, according to the drawing, but if that were bad I don't think you would be getting any power to the ignition at all (someone can correct me if I'm wrong)
Do you have a test light or volt meter?? check some voltage at a few points. Key on should give you 12V to the starter/ignition fuse. If the fuse is good, then it completes the circuit to the right handlebar switch- should get 12V to the kill switch, and if it is "ON", then 12V to the starter switch. Press the starter switch, should give you 12V to the starter/ignition relay. That should energize said relay sending 12V to the coil in the starter relay, which in turn connects the circuit for the big cable feeding the starter motor.

- January 31, 2017, 20:41:29 PM I have checked the fuses, every one that I could find all good. But it had a 10 amp instead of a 15 amp on the fuel, the battery is new, I even hooked my motorcycle jumper box on to it to check to see if a lack of power is causing it no change. Did notice that the battery was at the very lowest for cold cranking amps. they are going to buy a new one if I can get it even turning over.
The head light is completely unplugged needs a new one. I am trying how to cheat on the tip over switch to see of I can bypass it to check that. I think I am going to have to build a relay tester to test the relays.
I also plan on seeing if I can bypass the clutch switch, my question is on this bike does the clutch have to be in to start. I know some that do and a lot that don't.
What's this about the ignition switch, I have no idea what is on it at the moment. is there a issue related to this? anyone know how I can check what it is on the bike?
The bike is actually in pretty good shape, 10,000 miles and other than the head light and the signal I saw no obvious damage. all the tins are in good shape. To be honest it is in a lot better shape than my 01, of course my 01 is well over a hundred thousand miles. and I have ridden it hard.
