I recently replaced the head in my 1996 Toyota hilux SSR-X 2LTE after blowing a head gasket and cracking the head. I replaced most cooling components and adding new glow plugs. After getting everything back together I electrically disconnected the injector pump and cranked the engine to prime the oil pump reconnected the pump and tried to start but only cranked. I double checked all the connections and can’t think of what to check next. This is my first diesel engine. While checking diagnostic codes I received a 1, 3, 3, 9 flashing lights.
