Yeah chap, I reused the old ig. amp, and bought a new one as part of the kit from MSD. Also bought one of the brackets from them to mout them both Used the heat conducting paste on both ig. amp's, and i'm sure they are bolted down correctly, although to be quite honest i've not checked - I've been concerntrating my efforts towards the CPS / Phase sensor as everything i've read on here has pointed in that direction (tis a pain as on my old EFI XR2 turbo, i knew the car inside out, but the Escos means starting afresh! )

I have fitted the new ECT today and noticed that the wiring going to it has been cut- and re-soldered at some point, although heat shrink hasn't been used, so will be doing that tomorrow. I've also noticed that one of the wires going into the pahse sensor looks a bit shitty, but apparently Ford don't do wiring plug repair kits off the shelf - otherwise i'd have changed that tomorrow too just to rule it out... - could this be the cause?

Cheers for the help guys, much appreciated!

Edited to add:
Mart - thats exactly what I was going to do , but i don't want to have to get the car trailer there, only to then have to bring it all the way back if its something simple
