Truck cranks but hesitates or hicuups

i have an 88 cherokee and while im cranking it over it was almost seem like the starter dies then continues cranking.... or the engine will hicuup while its cranking.

once it gets started it runs fine...

brand new blue top battery, brand new starter, fuel pump, brand new coil, brand new cap, plugs are fairly new and wires are new.

oh yeah its a 4L renix

Long crank times on a Renix are common. That being said, if you're getting a hesitation, or "hiccup" as you call it while it's cranking, I would start looking at your grounds. If the Renix system isn't properly grounded, it creates all kinds of havoc with the system.

Yeah, hit your grounds really good.

Do a voltage drop test on the main cables: http://www.aa1car.com/library/voltage_drop_testing.htm

cleaned all the main grounds under the hood seems to do the same thing..

ill check the main cables now.

anything else to check for?

AW4 or manual?

Could be a number of things--remote rod adjustment; ignition switch adjustment; NSS adjustment (AW4); starter relay; solenoid--all of those on top of the battery, cables, grounds that you have already checked/checking.
