PROBLEM SOLVED

Guys thanks for all your handy suggestions and tips.
Before I provide the solution to my issue might I ask how you tell if the EHA is still functioning properly ? Being a sealed unjt with couple o rings, i do detect a small seepage around the fa e that fits to the fuel distributor. The 2 o rings seem okay but not sure ifnit needs replacing as a unit.

Now without further ado, the culprit of my woes is
IDLE CONTROL VALVE INLET HOSE
Yes if you recall I mentioned it backfarted when I went to start.
It was through the throttle body notnthe exhaust and it blew the inlet hose connected to the ICVout of the throttle body. A friend came over to throw a fresh set of eyes and with a bit of contortion be could see the end sitting in the middle of nowhere. Five minutes to undo and refit.
BAM Ignition start and running.

So relieved I really thought itnhad to be something simple but what.
Now tommfind out what caused the backfart......

Thank you once again kind people
