Just purchased it, and the second day it stalls out. It is acting like it was running out of gas, at a full tank I assumed it was a fuel pump or filter. Replace the filter pump ran 2 days. Now, I got it in for 3 weeks it when it start, I got it to start now I cleaned the throttle body. I went and got thrown a position sensors and whatnot from picking part Pick-n-Pull. I don't know I replace the rotor I mean the coil, cap, rotor, plugs, wires. Now when I give it gas it shuts off. I need help I can't afford a mechanic, and this is stressing me out bad. Thank you very much.

Hello, do you have a test light or multimeter to check for power at the fuel pump? The grey wire is a power feed to the fuel pump. If you think you're missing fuel pressure, then you need to verify the pump is getting 12 volts. You should also be able to hear the fuel pump come on for 2 seconds with just the key in the "on" position. Keep the driver's door open and listen for the pump to prime for 2 seconds.
