Triumph 1050 starting problem

Question edited for clarity.
Question moved to model category.

Probably took out the Engine Control Module. You need a good electrician, or shell out $259 on a guess. Or according to this, it fries the rectifier, (the white smoke you saw)

Try disconnecting the battery, wait a few minutes, reconnect it, and try again. If that doesn't work, then you will need to take it to a Triumph repaired for diagnosis.

Sounds like a crankshaft sensor

If you haven't done it already you might have them run it for codes to see if it is showing any. Autozone does it for free too.

i would suggest a tempature related fault check etc (engine tempature control ) switch

sounds like a wire short some where near the block

It sounds like you have to fit a ballast resistor in the power supply to the coil or get a 12 volt coil. Later spits (-ve earth) used a 9 volt coil with a resistor to drop the battery volts down when running, when starting the full volts are used but the starter will drop this to 9 or 10 anyway, this helped cold starts.)

check fuel pump pressure

Whenever you state a starting problem you should always give the last time you had a tuneup and what was done. In fact you should give information about any work previously done.

Local mechanic determined engine was flooded and started it by holding throttle to the floor and cranking 5-7 seconds - then the engine sputtered to life. It has run perfectly before and since and I'm at a bit of loss to understand why this occurred this one time - so far. It's been driven now 5 days with no problems.
