My 2007 Ram 2500 SLT 4x4 5.9L Cummins will not crank over. When key is turned on fuel pump runs constantly, Dash lights are on except for shift position, lights all work, blinkers work, radio. When turning key to start all lights go off on dash except for mileage and fuel pump stops as long as you hold the key. I tried to hook up diagnostic tool to read the fault codes but none that I have tried can establish communication. I have checked all fuses inside the TIPM and checked voltages across each one. everything there seems to be fine. I jumped the starter and it works fine. I have new batteries so can't be the batteries. This all started when I tried to install bullydog programmer. When doing so it never established communication. Talked with bully dog and they insure me that it is not the cause of the problem. For months before this I had been hearing a beaping sound while driving down the road. As if the truck was giving a fault. I payed no attention to it because everything was working fine. One other important thing is my key for the truck has been dead for at least a year and I have been using the key to open the door each time I get in. When I set the lock on the truck and I go to unlocki with the key the alarm goes off and I have to hurry and put key in ignition to stop the alarm. Please I need help seriously. I was trying to avoid going to the dealer so I didn't have to spend all that money. I have been trouble shooting for the past 3 days and I just can't figure it out. How do I check the power to the ECM, WCM and PCM? Somewhere I read if you get a direct short that the ECM will shut down if this is the caSE HOW Do I find out if it is shutdown and how to get it back up/ So many senarious but mind isn't the same as anyone's I have read so far. Biggest thing is that I'm not getting past ignition. Well hope someone can help with this issue.
