Does any one know with certainty why LT5 doesn't start right up immediately?

Was it the same way on the showroom floor?

This is the first electronically FI car I've owned that didn't do so instantly. Even the first one I owned, an L-98 that was in a poor state of tune when I got it, would start immediately. Foreign, domestic, 4's, 6's, etc.

On RARE occasions, it WILL fire almost instantly. But most of the time, it's 2 - 3 seconds. And I'll let off the starter then, and re-try.

I thought I read once on the boards here that ECM had to see some crankshaft position first, before issuing fire @ the plugs; this would mean, if correct, that it WOULD have exhibited the same behavior at the dealer, when new.

Does anyone know DEFINITIVELY the answer here?
