I have a 95 Roadmaster. It won't start on the first crank in the morning anymore, but it starts right up on the second crank (Had the fuel pressure checked and was told it's fine). It fumbles a little bit when I give it gas until it warms up for a couple minutes. I replaced the Coolant Temperature sensor by the water pump and it didn't help, but that code is still coming up. I'm getting Codes 14 and 15 which deal with the coolant temperature sensor and Code 18 which says "injector circuits"? I just ran the codes today b/c it stalled out on me pulling into my driveway, which never happened before. What does this mean and how do I fix it? If anyone can shed light on any of these issues or problems I'd appreciate it. Thanks.
