Starts then immediately dies dodge ram 2500

THAT IS USUALLY THE KEY - COMPUTER BOX THAT DOESN'T PICK UP THE SIGNAL, CUTS OF THE FUEL OR IN SOME CASES THE SPARK. HAVE DIAGNOSTIC DONE ON IT.

That sound theft problem or ETC problem. First verify batt condition. The CAN protocol don't work if the voltaje is less of 11.5 v

it has a new bat and alt

whats next to check

how do you check the computer box for signal

If you have changed the steering colum how do you get it to recognize the new key ?

Check the 140 amp fuse.

Did you ever get this sorted out? Mine starts, runs maybe 2sec, then dies. Not coughing, sputtering, etc... runs fine for 2sec then dies. Sometimes runs fine with just one start, some days takes 3-4 attempts, last night took 10.

what Was Thomas Answer my truck is doing the same thing

If it's diesel it's that you are not waiting long enough to allow fuel to get into engine through filter.... I had it till friends told me to wait longer and see what happened.

Mine did the same thing. Shop did a crank shaft relearn and it's fine not. It started right after changing battery. Told me it's a common problem.

Mine runs10 min and dies starts great and runs my findings no ground to ficm after it ran and wormed up my tipm was bad

2016 diesel remote start runs 2 sec then shuts off and won’t start. Try again sounds like the starter is clicking and won’t do any thing. Both battery’s have over 12 volts
