brant rip it out.
used to happen to me, would have to turn my car on and off like a million times so it would prime and eventually it would and i could start but sometimes took me about 5 minutes. got stuck so many times in the middle of roads where it would just F up, and was embarrassing where ppl would see I was a girl and be like did you run out of petrol......
but after i got it taken out completely it stopped happening andd never again had any problems
