95 Dodge ram 1500 5.9 liter, While cruising on highway, motor cuts out, check engine light flashes quickly, several trouble codes come up, all include short circuit to device, include code 53 which is PCM failure, how do i diagnose PCM failure or shorted wire, vehicle has done this for a few years, it does this periodically, seems very random, it otherwise runs great

First, the easy way is to just bypass the relays all together. Install a switch on the inside of the car like you would fog lights. This will solve the problem of replacing thing after thing and wasting money. Just a $7.00 fix. After doing that unplug all the sensors and then the battery for at least 60 second to reset the computer. Than restart the car and the check engine light should go out, may take a day or so. Same thing with your gas cap, re-securing it will take a day or so for the light to go out. Good luck. I love my '97 neon.

SOURCE: trouble code P0442 on 2001 dodge ram 1500

P0442 means you have a small leak in your EVAP System. your can try replacing the Gas cap since it's the easiest thing to do and reset the check engine light with a scanner. If the check engine light came back on then your going to have to go though all the Vacuum line in the EVAP system and connections. The other thing too is the service engine light should turn off when the problem is addressed and it may take up to three start ups to clear. Good luck and keep me posted, be glad to help, Recap, change the gas cap and inspect all the hose and connection's to the EVAP system.

SOURCE: 1999 dodge ram 1500 2wd 5.2L gives different intermittent codes

pcm posably but i think i would look at the grounds from the battery to body and bat to engine

SOURCE: Check engine light , trouble code 34

Your truck is OBD2 compliant take it to a local auto parts store and have them read the code for you they usually do this as a free service, if it doesn't have a obd2 port then your truck is not a 1996 vehicle.

SOURCE: po748 can tcc solenoid or vehicle speed sensor cause this code

One question? Did you clear the codes out of the system with a scanner? I believe that's the only way to do it now,unlike the old days when you could rest by disconnecting the battery. Hope this helps.
