I’ve got a 89 325i and about a month ago my car started taking a really long time to start, like 15 seconds long. It only does this when the car is warm. I replaced the engine temp sensor because i thought it was stuck on cold start injection. I also suspected a leaky injector but it started up fine after about a week of sitting. what is the next best thing to do? check fuel pressure, replace fuel filter, or is it something else that could be happening? The biggest thing that confuses me is the car still performs good, only problem is the super long crank time.
