Hi Don.

I too thought the exhaust was isolated but of course it's bolted to
the engine at manifold and there's a ground strap connecting drive
train to frame.

I've put that ECU through some paces. This being my first swap. It may
indeed be wonky.

My original thought was "fuel pump". But..... when attempting to start
it in parking lost, I noticed the MIL not coming on when key turned to
ign.

Neil.
