Engine turning over a lot before starting

I have a 96 F-250 7.3L and have been having an issue with it turning over quite a bit before it starts. I'm in South Louisiana where it's been fairly warm and unless it's really cold, I usually turn the key and it may turn over twice before firing up. Now it's having to turn over for about 3 or 4 seconds before starting and does it even if it's warmed up and just turned off. It is also sluggish for a few seconds when it first starts. It's almost like it isn't getting fuel. The engine seems to be performing well after a few seconds and I can't say I notice any loss in power. I put a fuel pump on it a couple of years ago (I live very close to my work so the fuel pump only has about 15k miles on it) and I just changed the filter a month or so ago.

Does anyone have any suggestions of what to look for? Any suggestions will be greatly appreciated.

Thanks,

The batteries are about a year old and the starter about 8 months old. It's turning over good and hard so I know that's not the issue. I'm pretty sure it has to do with fuel, but I just don't know where to start looking.

Look into fuel injector harness. My 01 was doing the same and I found the harness on the drivers side with burned connector. harness and valve cover gasket kit about $90.

Another thing is the battery cables. the engine turning over good but no start was another problem I had and the cables were internally corroded. New cables problem gone. The engine can spin but not getting enough power left to fire teh computer and all associated electronics. I cleaned the terminals before but the batt. cables fixed it.

The UVCH is always a good thing to check.
To check fuel you need a gauge hooked up to check it.
