DIY Guides › No Start
Long crank issues usually follow patterns that help you find the cause faster.
When to use this guide: It always starts, but it takes too long to fire.
If the engine always starts eventually but takes too long to crank, it's usually not holding fuel pressure between starts. When the pump stops, fuel bleeds back through a leaking injector or a failed check valve. By the time you turn the key the next morning, the rail is empty and you have to crank while the pump rebuilds pressure. Classic leak-down symptom.
