Unhappy Toggle switch back to keyed ignition fuel pump issue

so not to long ago, my 2001 f4i was stolen from me. a few days later it was recovered in the parking lot of a casino. After getting my bike back i found that the ignition was replaced with a toggle switch (something ive never heard of till now).

Anyways... i am able to ride the bike perfectly fine with the toggle switch, however, because this wont be acceptable for day to day riding i need a keyed ignition again.

I ordered a new ignition off of Ebay, which seems to work, however, the bikes fuel pump is no longer working. so the bike wont start.

the toggle switch still works and primes the pump but the keyed ignition wont. can anyone help me with this?

All fuses seem to be fine, and the toggle switch makes the bike run fine.

is it because its a cheap Ebay ignition it may be faulty or not correct?

Please chime in as id like to ride this summer and no put it off for another year.

Hi, if the ignition has different colours than original could be Chinese , then the pink wire might not have the diode in, check how many volts the pink wire is getting at the ECU, have a look at associated 929 and 954 posts. I'm assuming your in USA

Could you elaborate on how to check this. I'm located in Canada if that makes a difference.

Do you mean the pink wire by the ignition? And what should I connect the black end of the voltmeter too? And how many Volts should I be getting?

Depending on which ignition system your using (toggle switch or ignition you newly got) at the connector or the ecm, follow the Pink wire to the connector and back probe the connector on the pink with the ignition on to see how many volts you get, then do the same with the other switch,It's just that in UK we have the HISS

So the pink wire IS reading 12v, and I took apart the new ignition I got and can see there is no diode anywhere to be found.

So now what? Do I have to find a diode to drop the pink wire to 9v and just splice it onto the pink wire? Or is there a place to bridge the diode between wires?

Also if I need a drop of 3v would a 3v LED work? It would just be giving off light, which can be fixed with tape.

Yes ,just a step down diode , in the UK you can get 10 of these for 1 , so are very cheap , if not sure which way to place it in, although it will say, just bench test it with a 12v battery and use the multimeter , you want 9v going in the direction on the ECM , and solder it in then insulate, check internet for diode, here is a information leaflet

Another cheap way to prove this is to buy one of those small square 9v batteries, connect the positive side of the battery to the ecm pink pin (once you have pulled out the pink wire) and negative to earth, turn on and start up , ecm will get 9v direct, but maybe too much information
