bad ecm??
I have a 1998 dodge 2500 12 valve and have had problems with the batteries running low from time to time good alt and new batteries but one morning it would just crank and crank with no start i suspected shut off solenoid wasnt lifting(which is a 6 month old solenoid) killed my battery so that night with freshley charged battery it started right up but now headlights, radio,and all gauges wont work also the torque converter isnt locking up replaced crank sensor a month ago (wires got caught by fan) and while I had one of the batteries out when I opened the door there was a clicking which sounded like it was comming from the ecm under the dash does this sounds like a fried ecm to me
what do you guys think??
also no wait to start light

A sign of a bad pcm is no tach the alternator wont charge and no tc lockup or overdrive. I had the same issue I pulled the plugs out of the pcm got my trusty paper clip and multi meter and did some back probing. The pcm was dead my diagnostic port was also dead because of it. Ill see if I can fine what wires to test. Its easy to do on ur own.

It shouldn't be more than 2 hours to diagnose / confirm computer failure properly.
