91 ls 400 cranks but wont start
Hi all, I just bought a 91 ls 400 that cranks but wont start. Have checked timing belt, fuel and spark.
I got no fuel no spark. Changed ecu and nothing.I got no cel on and there's no power at diag box.I can jump fuel at diag box but not the power. Feels like security were on but security light not on.No power at igniters either. Anybody ever have this problem? 158k on vehicle.Any help appreciated.
thanks
