Dear Dave,

Thank you for pointing these out. I may have mistaken here. Just because the ECU is pictured next to the grounding pegs in the wiring's book photo, doesn't mean its grounded there!

And I used a 1994 wiring book. Unfortunately I don't have 1991 book with auxiliary injector.

Yes ALL ECU grounds are at the intake manifold.

And I found out one more thing. The main fuel pump is grounded at behind ECU (ground labelled as 31/10). So pulling the stalk may have disrupted the fuel pump's operation. At least thats my hypothesis now.

I stand corrected. Thank you guys!

Amarin.
