Hi all, I’m having an issue with my 1997 dodge 2500 4x4 Cummins. Issue started after I let the truck sit over winter months. The issue is when I turn the key to the on position my ASD relay along with the trans relay in the PDC tick very fast and loud. The ticking is accompanied by all my dash lights flickering to the same speed the relays are ticking. The truck starts and shuts down with the key, just won’t go into drive or reverse. Everything worked great when parked. Thanks in advance for any info\advice. Also this is my first post so not sure if I put it in the correct place. Be nice and steer me in the right direction if I posted incorrectly!
