Thanks for your reply, I have sent mine to him too. I havent yet understood how a short to ground can cause the failure as the ECU switches the injectors to ground anyway and a short would just by-pass the ECU. However I am not an electronics engineer and I plead ignorance but I would love to learn. Incidently, I suspect a fault in my aux.air regulator which shows 29 ohms when cold but I think it may short out when it gets hot. My reasoning is that a short in it would cut off the power going to the injectors by shorting out the supply wire to them as it is in parallel with the ECU. Purely an opinion at this point though but you may want to check yours. Its located under the intake bellows and very hard to reach. It gets its power from wire 34 which is joined to wire 30 from the fuel pump relay, in mid loom. Let me know what develops with yours Steve
