Datatool S4 Red Efi problem

[Yamaha Power]

Recently purchased a new lovely XSR700 with Datatool s4 red onit I have never like these with past experiences so I have decided to desolder it from the loom and reconnect the oem wires all back to factory now... we’ll so I think but now when I turn the ignition everything come soon as should but efi doesn’t sound and when I press electric start it just ticks over no start? Checked the efi fuse and Rest of them they all good? Any advice?

Took one off my VStrom last year when it failed and left me stranded in lane 3 of the M1.

Is the kill switch on? Wouldn't be the first time for me! Side stand switch?

Most of the cabling is providing power to the alarm and also to the indicators so they flash when arming/disarming. These won't have any affect on starting the bike.

Mine had the starter circuit and fuel pump interrupted which needed bridging when the alarm was removed. It's straightforward to do if you strip the bike to access the loom which I presume you did. Are you sure you have properly reconnected everything (thinking of the standard connectors here).

Other issue I had, was putting the tilt switch back on upside down which caused a bit of searching.

Basically, recheck all your connections which have been disturbed.

Thanks for the reply I’ll be sure to have another look and all plugs/connections and solidered wires and yes the electric start works just fails to start the bike because the efi wasn’t coming on, I’ll be sure to keep you updated also thank you.

Check where you bridged the fuel pump circuit then. Any stray strands which could have pierced the insulation of an adjacent cable?

If you have a test lamp or multi meter, you can follow the live supply back from the fuel pump and trace the break (assuming no power at the pump).
