Winter Startup?

[GAWKY]

I live in michigan and have a 1991 sierra w/efi i was wondering how i should start it on cold mornings, it stays outside all the time, i heard that you should pump it a couple times before you turn it over but would that do anything w/ efi.

Don't pump it. If the auto choke is working correctly you shouldn't have to. Pumping it will cause gas waste and possible flooding. Pumping it came from pre electronic ignition systems.

I live in Michigan also. I don't pump the gas peddle on any of my vehicles.

pumping doesn't do a thing to an EFI vehicles (bad or good)

dont pump, the buzzing sond you hear b4 your start the vehical shoule be let go until the end, its a prime charge (same as pushin the peddel a couple times on a carb moter), and let it run for a good 4 or 5 min for oil to start to flow, oil wont freeze but it will get really thick, i live in michigan too, and cold mornings are a bitch, but i would rather spend the few min worth of gas over what an under oiled engin could cost
