Fusable link? Did one of your injector wires ground out on something?

The odds of all your injectors failing at the same time and needing new injectors is very very low.

He means injector pulse

Doncha just love the Renix injection system....I know I got it on my Heep as well, you say you have pressure at the rail, spark to the cylinders but no injector pulse...typically they are ground fired from the ECU but get power from a relay or fusible link...I'd start checking the wiring for the injectors (power side) to see if anything is broken or defective on that side.

No power at the injectors what so ever... Any body know where the fusable link is or relay if there even is one. Looked in haynes repair manual, mabe not hard enough.
