I don't have a serious problem; just kind of annoying... My car starts hard, seems to be worse the longer it sets. It kicks over just fine, just wont fire up right away... I'm thinking possibly a Negative Fuel Feed as it gets worse the longer the car sets ... also if I prime the fuel pump a few times it seems to start up quicker. I'm not sure what else to check, So far I've replaced the Fuel Filter, Added a BBK FPR, and upgraded to a Walbro Fuel Pump, still same situation. Is this a common problem?
