i have a 2005 F250 diesel with 6.0 engine
. several odd things occurring with a little background info: truck was running great, but at idle the low oil pressure light would come on..example: it would run great, then at a red light oil pressure warning indicator would come on. The moment i accelerated the light would turn off. For whatever reason that problem has stopped.
Batteries are brand new.
Then....We recently had glow plugs replaced on driver's side. Computer showed p06872 and 0678 bad. So, we replaced all and installed a new glow plug harness..then reset and no further problems evident on computer. But here is the weird part: truck started great and seemed to run very well, but intermittently all of the dash gauges would not work while driving, i.e., fuel, rpm, etc would all show zero. Then gauges would work again. i arrived at my destination and shut the truck. When i returned to the truck a short while later it would not crank, and would not start. I heard the usual buzzing sounds and ding with the key in the ignition. If i opened the hood and disconnected and then reconnected both batteries the truck would start and run fine.
Yesterday morning I started the truck. I opened the drivers side window to help cool off the interior. It started to rain, so i attempted to close the window. The window would not go up and i noticed the gauges all dropped to zero, but the truck was still running. I shut the truck and when I tried to restart it, the familiar buzzing sounds, ding, and glow plug light all came on...but no crank and no start.
I disconnected the battery terminals and then reconnected them, but still no crank and no start.
so, i disconnected the batteries again, turned on the light switch and let the truck sit for several hours. This morning I went out and reconnected the batteries (which i know have plenty of juice). No crank, no start!!
I checked the following: i put key in ignition and could hear relay click under steering wheel. I heard all the usual buzzing sounds.
I checked to make sure the shift lever was securely in park. btw: there is no wobble on the shifter or on the ignition switch itself.
Then, i went to passenger side of truck and unplugged the single wire connector that goes to the starter
. I took a piece of 10 gauge wire and tried jumping from the male end of the starter wire plug to the positive terminal on the battery. the starter did not crank.
