Hi everyone,
Im new to the forum and hoping for some advice. Im currently working on a series 2 rs turbo for a friend but I cant get to the bottom of this issue.
The story behind it is, its been to multiple garages and had many parts throw at it, new pump, tank, fuel distributor rebuild etc but they were unable to get it to start.

Since getting my hands on it ive been able to get it running but not without some problems in the background. The main one is, it will not run with the EHA/pressure actuator connected. If I plug the eha in while the engine is running it just dies, like someone has turned the ignition off, no spluttering or anything like that.
The EHA plug has 8v on when disconnected but 1v when connected. The resistance of the EHA is within spec so it isnt shorted or anything. The wiring has been repaired in some places and has had multiple replacement plugs which I will be tackling next weekend to make sure everything is good, so far it looks to be.
Any input in the meantime would be highly appreciated though.

Thanks in advance
