My 95 F-350 with a 7.3 has been giving me issues lately. I finally figured out that the main connector from the engine to the fuse block and IDC and Computer was corroded. So I cleaned it up with electrical contact cleaner and used a fine brass wire brush and also cleaned the ECM connector and the IDC. After cleaning I put dielectric grease in all of the connectors. Is this a problem? I now drive about 5 miles or so and the truck stalls and all the warning ad wait to start start to flicker and you can hear the glow plug solenoid activate and deactivate. I can turn the key off them back on and it ill start up and run again. Now all of the sudden the when I hook up my Snap On mt-2500 it won't communicate with the truck. The truck has over 269k on it and has had NO major work done to it since new. It has been a very well taken care of truck since day one. Would the dielectric grease have anything to do with it? I know the problem is electrical and not mechanical.
thanks for any advice in solving my issue.
