HELP PLEASE!!! Trouble Code P1670, 0381 & more
2002 Excursion 7.3 diesel has been starting fine and started fine Friday. Took it to town in the pouring rain so lots of standing water in the road that was driven through. Get in it yesterday and it will turn over but won't fully crank. Weird thing is interior lights stay on (which I'm sure drained battery). Jumped it off and lights stay on even when running and all doors/hatch shut good. Diablo Predator shows codes P1670, 0381, 0672, 0676, 0678. Glow plugs changed last year (code cleared but keeps showing up). Get in it this morning and same thing...turns over but won't crank. HELP! I need my Excursion running!!! Where do I start?

Since you mention water the first place to check is the windshield seal and find out if it is leaking onto the computer.
Peal back the rubber seal and check for corrosion.
Then dive under the dash and look for signs of it leaking on the computer.

Thanks for your input! I appreciate it greatly. I do have a small windshield leak. It does not leak every time it rains but when it does leak, it drips into the interior. Would I still need to check under the dash if it a small drip to the inside and where is computer and what signs should I look for? Sorry for the questions...Although I do a lot of research regarding issues with the EX, I am a woman so it doesn't come natural 
LOL!
