engine bay wireing (8v digi)

[Craigwilson]

here is the diagram of some of the things on the 8v. what I need to know is are these readings correct or does a problem appear here, can anyone help or point me in the right direction.
the car dies when the blue temp sender is unplugged and it idles rough and is misfireing.

Take a look at the link for a chart of expected resistance readings for the blue temp sensor, although the fact that engine changes when you disconnect it is a good sign

As for the bad running, I take it you've also checked timings and things like ht leads/spark plugs and so on?

it shouldn't die tho, I've tried literally everything, right now it won't start Atall, but when I get someone to crank it and I unplug the injectors it fires for a second then dies but if I plug it back in on time while giving it throttle it will start and run awful switch it off and it won't start again, it's been all week now...... I give up
