Check your battery terminals.

Do you know how to use a multimeter?

yeah I checked the ohms or whatever on the mpi under the radio, I actually replaced the mpi fuse, the part under the radio on the passenger side, just bcuz I had spare one, traced my wires for the battery since it's in the trunk, put on new terminals, and right now it's starting, but somtin keeps trippin bcuz even if I touch the window button I have to wait a second and take the terminals off, and whem I took it down the road it would throw a cel then clear and backfire
