No start issues

[Jpress82]

2021 ram 2500 Laramie 6.4 gas. Ill start with it is not the starter. So my truck will not start i push the button nothing then periodically it will start. I changed the starter relay and it started 3 times but it had been cooling off for 1hr. Went to a couple jobs and then it i had to turn it off then on to engage 4wheel which is another electrical issue turned it off started it immediately and nothing for about 4-5 minutes pushing then button. Any suggestions would be much appreciated. Thank you!!

How’s your battery? Has it been load tested with one of those toaster red hot ones?

Battery your first start, load tested with analog not digital, than go from there.

being in Connecticut, the cold weather does a number on batteries.

Definitely agree, but replaced battery and alternator 1 month ago to date.

When I let it "cool down" sometimes not even 5 minutes it will start. Im leaning towards starter solenoid. I replaced the relay fuse.

Mow to the real issue abs not sending signal from passenger side. Replaced the abs sensors both but still have dash lite up like Xmas tree. Where would I start ti look for a broken wire?

I assume you’ve verified all the grounding straps in the engine compartment for cleanliness and tightness?

 

[Jpress82]

Yes I have

The starters on the 6.4 are notorious for going bad, also the ground and battery cables are known to be or become loose or corroded. Our 2022 company owned Ram 2500 had the starter replaced at about 30k, it was an intermittent issue at first then got worse.

Same. My starter died at the 30k mark. Now at almost 60k, I just replaced the battery. It's a '23 2500.
