I'm sending you all bills..... ;D
Seriously... Diagnostics  as well as repair is what I did for my working life..keeps your brain working. Armed with books, and 40+ years of experience, I'll help where I can, or at least try.

If sooo, you need to be one the receiving end of the donations pool. And that's cool.

I did those things last night, I even replaced the negative ground cable with a new one I had bought a few months ago.
Checked key wire connections.
No go, then did ecu test, all the lights stayed on.
So the instructions in the earlier post said the problem is the DFI if that happens.

I talked to the local shop today, and told them what was happening,  and the symptoms.
I never mentioned the key switch possibity.

The owner said they have had 3 fi vulcans with similar symptoms over the years, and he said after much parts changing, and labor, it was the key switch on all three..

I guess I will just cough up the cash for the new key.

But with my luck, it will be the pump...

I still try what troll suggested after I get the new key in to see if I can figure out a way or mod to bypass that feature for future riders..

sure don't want to steer you wrong, but it's kinda hard doing this over the internet...I have a 2001, so yours MIGHT be a little different, but.....There are 5 wires connected to the ign switch..one battery + (white wire), two lighter wires that run to the front and rear lights, one heavy wire that runs to the junction box (brown), and a lighter gray wire that runs to terminal 3 on the ecm. This is the tricky wire. According to the wiring diagram, it's there, but the legend for the ckt. pins says it's unused. This is the wire that was not getting proper voltage on mine, and caused the whole problem. The thunder ign. switch the P.O. had put on deteriorated at he connections, and the inline resistor failed. Incorrect (or no) voltage on this ckt. will cause a no start condition....cranks, spark, etc, but no fuel pump. There is a link on the mods and tips section talking about this problem. I found the link AFTER I spent way too much money and time...http://www.vulcandrifterriders.com/jobearIgnition.html
Notice that the 100ohm resistor goes into the line to the "unused" pin#3 on the ECM......

Start at the beginning...

Ensure your battery connections are good, plugs and wires good and secure. Make sure the connections are good to the ignition switch. (I replaced a bad battery a couple of years ago... the replacement new battery was also bad - it showed full charge, but failed under load. New battery doesn't necessarily mean GOOD battery... though this is unusual. )

Try to start... if it fails, run the ECU test. (Link in previous post).

That will show any problems with: Sensors for throttle, vacuum, inlet air temp, coolant, atmospheric pressure; but also for the vehicle down sensor, pickup coils, injectors, fuel pump and ignition coils. If there are no fault codes, you can pretty much eliminate those things.

The reason I was asking about testing is I just spent $100+ on a battery I apparently didn't need, I would hate to spend 100 on an ignition I didn't need.

Things are tight at the moment as my wife just had surgery the day before thanksgiving, and I am having surgery on the 28th.

And it is my only means of transportation. (Other than having the wife get up early and drive me to work)

Thanks for the info on the hidden feature..

The wiring on the switch has an interesting hidden feature. There is a resistance wire or resistor built into the circuit that sends a 5V signal to the fuel controller. They did this to prevent hot wiring and ride off thefts...That was where my thunder switch was causing the trouble. A stock switch is like $90, and comes with 2 keys that don't match your other locks...bonus!

Mine is stock, (as far as I know)

Can you tell me this Troll.
If I direct connect the 2wires from the key switch, should it work the same? Just to test to see if it is the switch?

I have done some googling, but haven't had many hits on places that sell 1999 1500 drifter ignition..

Any idea what they cost?

That is exactly the same symptoms mine had. It  had a thunder ign. switch, now it has a stocker...

ok, now the lights stay on, and the pump doesn't run at all.

I ran the test, grounded pin 37, and when i turn the ignition back on, the FI light comes on, so according to the thread,  it says there is a problem with the DFI.

any suggestions?

This provides ecu testing info. This shows any faults in a bunch of sensors, fuel pump, injectors, coils etc. If there are any.

Thanks for that info Troll.

so, i have been trying some trouble shooting, when i turn the key on, the fuel pump runs, then quits, the FI light, temp. and oil lights all go off.

When i hit the start switch, if the temp light, and FI light come back on, it won't start, but turn the key off, then back on, the pump runs, the lights go off, and i hit the button again, some times the lights come back on and it won't start, some times, they stay off and it fires right up.

Something is strange.

tried it 12 times in a row, it started 5 of the 12 times. the other 7 times, the FI and temp light came back on, and it would not fire.

ideas?

Doesn't have a real post...did the fuel pump run the first time? I (and quite a few others) had to replace the ign. switch due this intermittent no start problem. Mine would do it after along run, and would restart after it sat for a little while. No fuel pump, no start. The last time I had it out before discovering the ign. switch problem, I rode 350 miles that day, and then it wouldn't start about 1/2 mile from my house, after I filled it up...had to walk home...could have been a hellofalot worse...
