Trying to resurrect my 90 Paso 906 after sitting for 10+ years. Timing belts and clutch, fluids have all been done. When the shop tries to start the bike the vertical cylinder doesn't fire. They've confirmed the coil and sparkplug so now they're thinking its the Digiplex.

Based on on other posts I've asked them to confirm the Digiplex pin voltages and the crank angle sensor (didnt know it had one).

Also - found a great Digiplex repair/replacement options at Carmo - https://www.carmoelectronics.co.uk/inde ... _2025_2061

Any suggestions on other things to check or do i just bite the bullet and get a Digiplex?

Mine had the same problems, except the fault started as intermittent then went permanent ,fitted an Ignitech unit very happy so far
cost was 188 euro for unit and an adaptor to connect wiringrather than spend time cutting and joining cables. fitted without any problems ran straight away once I remembered to turn fuel on
