E85 will have longer cranking for cold starts, just comes with that fuel type if you are comparing it to gasoline cold starts
Computer does run the CHOKE but E85 still needs a bit more heat to be ignited by a spark, and each compression stroke of the piston heats up a cylinder a bit more, so you just need a few more strokes with E85
If weather gets colder, morning starts, that will also add a bit more time, it just needs a bit longer to get heat in the cylinders high enough
If it seems excessive cranking is needed then you may have a pressure leak in the fuel system
Fuel system should hold pressure for a few MONTHS, above 25psi, running pressure is 55psi
But system can bleed off pressure inside the gas tank so its not a "leak" of fuel just pressure
Try cycling the key on and off 3 times, then try to start, this runs fuel pump 3 times and adds 30psi pressure if it was at 0psi
If it starts faster then you do have a pressure leak
If there is no smell of fuel then leak will either be in the fuel pump's check valve or in the fuel pressure regulator(FPR) in the fuel pump assembly
In either case you should replace the whole assembly, pump and FPR
