Okay the problem of my car dieing on me before was actually my fuel pump. Since I should be getting the rest of my parts by Monday I figured why not just get a 255lph walbro fuel pump. SO I installed that today and tried to start her up. No good, car won't start.
Maybe it was the factory intake pipe I broke off the throttle body and decided to leave it off until she would start. So I put the intake pipe back on, but leaking bad, because I broke the piece right where it holds onto the throttle body. So After a couple of cranks the car would start and wouldn't hold idle. I keep trying and bamn finally starts. I didn't drive it though so I just shut her off. My dad comes out and tries to start her up no fire. He calls me and said it won't start. I get off of work and started it and it fired up. So I drove to the gas station and put more gas in. Come back home and my mom tells me to run and get some pop. Went back outside and guess what? IT WONT START. Does someone know whats wrong with the car now? Is it actually the intake pipe, I mean its not held on tight. We dont run a MAF unit so I don;t see why I would have trouble starting the car. Any info would greatly be appreciated.
