CGT fuel problem suddenly super rich then dead

[James Bell]

Matt:

I believe your problem is centered around the
frequency valve. The one that controls the
fuel pressure Via the CPU signal. Start with fuel
contamination. Move to wiring faults, then to
It's controlling signal. Scope out your O2 sender.
As mentioned by others.
