问：更换电池，燃油泵和汽车的启动仍然缓慢。当它启动时，它会在没有警告的情况下关闭。燃油滤清器很好。

其他可能性是什么？仪表板上没有检查引擎灯。我们已经更换了电池。它始于过热。我们固定了散热器。一天早晨，电池刚刚死亡。我们更换了它。这些一系列事件发生在一个月的时间范围内。然后汽车不会启动。我们换油，过滤器仍然没有开始。 Realised fuel pump had issues. Replaced that and checked engine wiring. Pushed in a fuse that appeared to be sticking out under steering. Now it starts after a lot of cranking but after driving a short distance it just loses power and shuts off. Won't start for a while. Then it starts later only to repeatedly shut off. Can't find DB II connector on this model so diagnostic test is another issue. What could be the other possibilities?
