I've ordered a replacement DME relay, although it tests OK

any other ideas please

It appears your problem is fuel related since fuel into the intake starts the engine
momentarily. If the DME relay doesn't solve the running problem and:
1. The fuel pressure is not O.K. Then you can try to ground pin 20 of the DME ECU
which should cause the pump to run for checking the pressure. If still no pressure
then the pump is possibly bad.
2. The fuel pressure is O.K. Then there is a injector driver problem possibly caused
by an over-voltaging alternator or possibly other ECU circuitry problems.

If the DME ECU is the problem, Pelican Parts does provide a rebuilding service.
