Hi I'm new to this forum. I have a 1997 Freelander 1 with an LN diesel engine. I have just replaced the injector pump and this morning tried starting up. It started but didn't run. I tried a few times but couldn't get it to go. I bled all fuel lines and had the battery fully charged. Then the engine refused to turn over! I've checked all fuses and there's no problem with them. The immobilizer isn't the issue. What could be the problem?
