If it will run at all, yes.
Have you tried spinning it on the starter for five seconds and then pulling the
codes (without turning the ignition off, natch)?
Lifting the plate provides mechanical fuel enrichment. If it won't run from
cold without the plate lifted, there are a few ideas. Favourite still has to
be a complete failure of the control pressure regulator (a.k.a. warm-up valve)
which is putting system pressure onto the top of the fuel distributor plunger.
I've got a dead one here that has failed in the _other_ direction - applying
too _little_ pressure - that you could swap in if you feel like trying.
I've forgotten how serious your manipulations were - how did all this start?
