Interesting.
I wonder if having the high pressure oil switch connected to my
Vanagon oil light, had anything to do with this engine "not stopping".
Especially since the hand brake would stop it. I corrected it. Hasn't
happened..... yet.
The other theory was that since the FP, HO2S, Power supply (ECU), and
coil relay (the Jetta coil uses a larger gauge wire than my Westy did,
so I installed this relay to carry power to coil) were located over
the exhaust, maybe the "coil" relay was getting hot and sticking.
Something I was concerned about prior to running this conversion. As
it turns out, the relay box was almost too hot to touch being right
over the exhaust.
I moved it to the passenger side. Maybe cooler relays behave better.
Thanks Dennis.
Neil.
