2016 Ram 1500 Diesel Laramie - Randomly does not start

Asked by Matthew Feb 10, 2021 at 02:08 PM about the Dodge RAM 1500

Question type: Maintenance & Repair

Hello, my 2016 ram will randomly not start.  I press the button and the starter
cranks, and cranks, and cranks, but it doesn't fire.  If I walk away and come
back after an hour or so, it will start up like nothing is wrong.

It seems to happen after it has warmed up, and then sit for 1-4 hours, and
then I try and start it.

Fuel filter changed 10K miles ago, and I've tried tapping on relays, which I
thought worked once, but may have just been a coincidence...

Please help!

Are the glow plugs/screen working? Fuel pressure and fuel filter AOK?

Hello F_O_R, The dash readout shows the glow plugs come on and go off as normal, so I'm assuming they are functioning, no codes... Fuel filter has 10K miles, but I have ordered an OBD link so I can check the fuel pressure. With that being said, what has me perplexed is that if it does fire up, it runs normally, no issues? It may start up fine 5-6 times, and then it won't. I did YouTube it and found a decent video on a similar crank/no start issue, but it was not intermittent. My next steps are to check the Fuel, Fuel Pressure and if the Injectors are firing. If that checks out, I may have to haul it in to the dealer... It's 4000 miles out of warranty (grrr...)
