i just read this:
i just read this:
Date: Sept. 8, 2000 Models: 1998-2001 BR/BE Ram Truck with Anti Theft system (LSA)
1998 - 2001 (AB) Ram Van/Wagon 1997 - 2000 (AN) Dakota 1998 - 2001 (BR/BE) Ram Truck 1998 - 2000 (DN) Durango
NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A VEHICLE THEFT ALARM (VTA) SYSTEM (SALES CODE LSA).
Discussion:
Part of "No Start" diagnosis on vehicles equipped with VTSS should include a verification check of the power supply to the Central Timer Module (CTM). The CTM provides the Powertrain Control Module (PCM) with an "OK To Start" message via the CCD bus. If the message is not received by the PCM, the PCM will not allow the engine to start. Initially, the engine may start and stall but will eventually not start at all. Most CTMs are supplied battery voltage through the power door lock fuse. An inspection of the fuse should be one of the initial diagnostic checks performed. If the fuse is operational, a verification check of the communication system from the CTM can be performed using the DRBIII. Attempt to communicate to the CTM. If the CTM does not respond to the DRBIII, the DRBIII will identify a "No Response From Central Timer Module" message. A "No Response From Central Timer Module" message may indicate that the CTM is not powered up. Please refer to the "Communication" section of the appropriate Body Diagnostic Procedures Manual to assist in "No Start" diagnosis due to communication problems from the CTM. In addition, the "Vehicle Theft/Security" section will aid in the diagnosis of "No Start" issues involving the VTSS system.

There is no alarm in the truck, Ive never had a remote or anything like that for it. Whats the PDC? I checked the fuses in the dist. box under the hood on the drivers side fender if thats what your talking about. Nobody around had a computer for it so I ordered one on ebay with a 1 year exchange so Im hoping that will fix it I have a feeling I fried it when I hooked it up backwards. When the truck started with the last engine for one of the last times it did put up a CEL, but that was right before I plugged the charger up backwards. It started once since I plugged it in backwards, ran like *** would not even idle and then I did the engine swap due to a warped crank.

It seems like it is the computer since I have no power to the crank pos. sensor, coil, fuel pressure ect. I know the grounds are hooked up all the guages work, all lights, starter ect.

Are you using some sort of guide, like a Haynes or FSM to do these test's? IIRC the crank sensor has no volts going to it unless it's running. So basically it can't be tested. And yes, the PDC is the black box under the hood. Power Distribution Center

Yup I was going by the haynes manual, it said to plug the pos. lead to the to the purple/white, and the neg. to the black/light blue. With the ignition on there should be 5 volts to the connector.

yes that was the fuse which when I pulled it out and put a tester to it I had .03 volts. I tried switching the relays, checked all fuses and connections, still have no power.
