Thomas Spagnoli: workshop approach for Triumph Sprint ST 1050 injectors connected allow crank but engine never catches

With Triumph Sprint ST 1050 injectors connected allow crank but engine never catches, the useful question is not 'what part is famous for this?' but 'which system stopped doing its job, and under what condition?'

1. Start with model, year, mileage, engine type, recent work and the exact symptom.
2. Separate opinion from measurement: voltage, pressure, compression, plug condition, code history and visual evidence.
3. Make a small checklist and tick it off in order. It is slower for five minutes and faster for the whole repair.
4. When in doubt, return the machine to a known baseline before tuning or modifying.
