alright sfter i started up my new 383 and broke it in properly i shut it off then when my friends wanted to hear it i started it up again effortlessly. After sitting all night and then changing the oil i tried fireing it up and all that happend was it cranked with no fire. I have spark and i have fuel there is no air blockage so what the hell could it be?

try starting it with the throttle wide open or partly open.. you may have to play with it too while you're turning it over.. my 385 doesnt start without me doing that..

even if it is a fuel injected engine?

in a fuel injected car holding the throttle wide open while cranking will put the car into clear flood mode, and not fire the injectors to help clear out the excess fuel.

alright then. well i tried to start it this morning and its rummbled right up lol so im happy but confused oh well. timemd her in today and oh man is it a beast! lopey at 900-1000 !
