Problem with Freelander1. Starts up intermittently, revs to 2000 rpm then dies. simply started doing that after parked without battery for a couple days. All sensors swapped out no change. Took off fuel rail. infectors fire for 2 seconds then shuts down. fuel rail stays pressurized. continues to run if sprayed with starting fluid or if fuel is simply dumped into the intake manifold. any ideas appreciated. Again problem is injectors shut down.
