    Since it's a Jimmy, I assume you swapped the 350 into it. The original V6 and the 350 are both TBI not CFI correct? Did you change processors too? Sounds like it's not getting enough cold enrichment. Might be a coolant temp sensor problem, or the "crank" circuit may be dead. Should have a fuse in the fuse box labeled "crank"....
