If the cranking speed drops even with a new battery you have a bad battery cable or connector.Will try testing again, I bought a new battery just to see if it would remedy my issue but I still had the same issue. Since then I returned the new battery since it did the same thing
When the engine just plain won't start until after it has cranked considerably and this only happens at the first start of the day or when it has been sitting a considerable length of time, I'd suspect the fuel pump's check valve has gone bad and is leaking, allowing the gasoline that is supposed to stay in the fuel rail adjacent to the fuel injectors to instead drain out and back to the gas tank. The extended time to start is usually the amount of time required to get fuel back from the gas tank up to the fuel rail. If that's the case I'd replace the fuel pump. If you do end up doing that, avoid store brand fuel pumps. Not even if it comes with a "lifetime warranty" like Autozone provides for their Duralast parts... they seldom hold up. Bosch is the preferred brand but they're getting scarce. Delphi is a second-choice brand that generally receives good reviews. Again, don't install a store brand fuel pump, it won't last long enough to make it worth your time. Even if it does come with a lifetime warranty.
