I just bought this 2000 sport and I got to crank it 2 times every time I start it. only occasionally will it catch the first time. the guy I bought it from put an after market intake, I'm not sure if that's screwing it up. I will change fuel filter and check fuel pressure. my chevy fuel pump activates when key is turned on and off and that engine catches immediatly. new member, so I hope I'm doing this right. thanks guys.
