I recently just bought a 87’ z31 n/a and it’s my first car. The last owner let it sit for three years after the fuel pump went out on him so I recently changed the spark plugs, wire, crank angle sensor and of course the fuel pump and filter. Since it’s getting spark now it’ll turn over and start for a second with starter fluid and I know fuel’s getting at least past the fuel filter but since it still won’t start I’m thinking it might have something to do with the fuel injectors.
