so selling my FC but 1st
 

got a new batt N alt
n now its pulling this whole flooding issue , i can smell the gass its cranking but not starting

every once N a while it WILL start, it runs rough for about 5 seconds than dies

im confused as to what this is.

it ran just perfectly before, but starting has been an issue from the start

Did you check compression ?

Did the battery die on the car and then you tried starting it? Right now your car sounds flooded, remove the ecu/egi fuse and crank it over for a while, then put it back in to start. If that doesn't help, take out and clean the plugs - and include turning over engine with egi fuse out.

If this has been happening a lot you could have a leaky injector, a vacuum leak, or as sj mentioned your engine compression may be decreasing.

or coolant seals are going out

????????
