Worcester junior 24i combi

[Si H]

Hi new to forum been plumbing for over 30 yrs for my sins! and back on the tools after a number of years behind a desk supervising!

i presume this question has been asked and answered on numerous occasions but i have a problem with the 24i combi in that it sparks but no ignition!
After doing all tests etc on the pcb connector for ohms to the various points eg gas valve etc and continuity tests the flow diagram in the book says PCB if not replace gas valve!

Im sure someone on here has dealt with this but i need to be sure as i have ordered a new pcb and at over £100 + vat i dont want to waste money for the client.

Have also confirmed gas is at valve on the inlet side.

Any ideas guys?
