My 1997 Defender 90 doesn't want to start in the morning, I have to use starting fluid but then it starts up just fine the rest of the day w/o starting fluid. I've been told to check my starter injector and I've also been told that the 97 D90 doesn't have a starter injector, from what I can see it doesn't. I just replaced the fuel pump. Everything else works fine, car has around 60,000 mi on it. Anybody have any suggestions?
