Hopefully I will receive help on this issue that has come out the the blue...
2002 Dodge Durango R/T, had the doors locked while parked for 4 - 6 hrs, went to unlock the drivers door with my key (I do not have a key fob) the vehicle "panicked" and the horn was blowing for about 3 seconds and stopped on its own. I started the vehicle and it ran for about 15 seconds and just died. I tried restarting and all it would do is crank over. I swapped fuel pump relays and tried disconnecting the battery a few times. I was able to get the truck to restart once, but again, it stopped running shortly thereafter. I had to get the Durango towed back home. While trying different things, I noticed the odometer switched over and gave me the "No bus" message. Also, the speedometer is maxed out and so is the RPM gauge, (see picture)...I've done some online research on this already and it sounds like it could be a few different things...
I did come across the Problem 1 thru 6 process for checking the 5v power supply from the PCM and started going thru that. I found that I DO HAVE 5v at the TPS and MAP sensors...where do I go from here? What I gather from the 1 - 6 process is that if I have the 5v reference voltage at both TPS and MAP sensor connectors, (see picture), then there isn't a problem with the Crankshaft Position Sensor (CKP) and Camshaft Position Sensor (CMP)...correct? Or does this 1 - 6 process even apply to my 2002 R/T model???
I've also read that my PCM could be at fault...Not to jump to conclusions on this...but If so, how do I test this? What is the process about getting a refurbished PCM for my 2002 Durango R/T and making it work? Recommendations on where to purchase a refurbished unit? Will it be plug and play? I only have 1 key for my Durango and it is not a key fob...just a key with (I assume a chip).
Initially I was thinking that this problem has to do with the "security" feature...but now I'm not so sure. Possibly? (I do not hear the fuel pump running when trying to start)
I jumped the fuel pump at the relay station and it DOES run...but truck does not start with it running.
Just seeking help or ideas from anyone who may have experienced this or something similar with their Durango! Thanks in advance!
