Wink Ford mondeo 1.6, 16v, 94 plate, motor code L1.

Customers complaint, no start and misfire on cyls: 2+3,

This sounds like an ECU fault, the triggers at the coils are 1 = cyls: 1+4, and 2 = cyls 2+3, so do we have a trigger out at the coil for cyl: 2+3.
To test this you need to test the coil triggers at the coil, using the scope.

The two outside cables are the coil triggers and centre is the supply, with the scope we found that the one trigger was in fact missing, and wiring back to ECU is ok.
Fault here is the ECU, and a new unit did the fix.
