I have a 94 ram 2500 4x4 with a 360 in it. I was driving down the road and it just shut off completely. I'm not getting juice to the fuel pump or the ignition coil. I have tested both and they are working fine. All relays are good as well. Any ideas what the problem could be. I purchased a control module thinking that it might be the issue, but I can't find it's location on the truck.

Check fuse link no.4 and 8 and also test out the ASD relay-it powers the coil/injectors/fuel pump thru the fuel pump relay-

Thank you for the quick response! I have checked and even replaced them. I am so lost right now. I can take out the ASD relay, turn the ignition on and hook a grounded wire to one of the connections and the fuel pump kicks on, but I still cant get spark to the ignition coil. Any other suggestions?

I am working on a 94 truck and the same problem, check the voltage from the PCM supply to the crankshaft position module, if it is 8v then probably it is the crankshaft position module, I did the same for the one I am working on, replaced the CPM and it started right up. Take heed though, it is very hard to get to, so be patient, you can replace it. It is around the 2:00 position on the transmission, on the passenger side.
