Default 2013 5.0L - Excessive crank at cold start.

I've just noticed in the last few days that the engine will crank longer at a cold start. After that, it starts normal when engine is hot. I've seen some other posts suggesting fuel injectors for older engines. Any thoughts would be appreciated.

I wouldn't go that far without ruling out your battery or starter first.

When the battery begins to lose CCA's it takes more to turn it over. The cold can especially affect the batteries ability to produce peak CCA.

When starters begin to go south it also has to try harder to turn the engine over.

+1 , check battery or starter first. failed injectors or plugs are associated with a rough idle/reduced performance, if your dealing with normal performance then you can usually rule out FI and plugs
