Advise needed on non-starting 1992 1.1L HCS (pushrod) Ford Fiesta. This is the Cfi, distributor-less model.
Daughter's car of past 15 months during which time a reliable starter & runner. 10 days ago car stalled after running a short while and then refused to start. Renewed spark plugs, crank angle sensor; checked plug leads etc and verified spark (but possibly a bit weak & yellow) with plugs laid on cylinder head. Engine cranks-over fine but fails to fire (absolutely nothing) even with Easy Start straight into inlet manifold. Also checked cylinder compression and valve actuation and starting with fuel pump fuse removed in case of flooding.
Hypothesis: this is an ignition related problem; spark occurring at wrong time or breaking down with compression hence total lack of firing. Opinions please.
