I'm new to this forum so hopefully i'm doing this right.
Last week my truck started cranking for a long time before it would start. Then sometimes it will start as soon as the key is turned over. About a month ago I had the H&S mini maxx installed along with afe stage 2 intake and 5" down pipe back. I have drained the water separator and fuel filters were changed about 2 months ago along with oil and filter. Any help would be appreciated thanks
Also when running the truck runs like a champ

How did the filters look when they were changed? I would probably try change them again. How about any codes popping up in the h&s?

The filters looked good when I changed them but that thought crossed my mind on changing them again and as for the codes I've tried to check the H&S monitor for them after each time it has done this but their weren't any codes popping up

How old are the batteries? Just an idea, I've heard the trucks doing weird things when batteries are low

Any codes?

My first guess would be batteries. Have you noticed a difference when the motor is hot vs cold, or the temp outside? It could be as simple as a loose battery cable.

Batteries can be tricky things... more so when there are two of them.

I'd go to a parts store and have them hook a load tester up to see how the batteries are functioning. They seem to be the culprit (plus they're easy to test).

[Rtirey2]

Not sure on the batteries I just bought the truck about a year ago but I have yet to see any codes pop up when it happens I've also checked the screen on the monitor of the H&S

Doesn't seem to matter hot or cold. Would the batteries have to be pulled in order for them to do a load test ?

Not necessarily. It depends on where you go. Most autoparts store will do it on the truck for free. Worst case you'll have to disconnect your battery temporarily.
