so i went down to CT today to see if i could finally get my truck out of my brother's yard. thanks to the help of all of you who gave me advice i got it running and the way it drives you wouldn't think it sat a day of it's life! my brother plugged in the block warmer 2 hours before we got there so it was pretty warm. we hooked it up to thee jumper cables for like an hour and tried to turn it over a few times but nothing worked (even ether that we lit on fire to help warm the engine. i guess thats an old trick). finally we decided to see if the fuel rail was even getting fuel (DURR). of course it wasnt so i'm glad i forgot to bring back the fuel pump i bought a while back because after 2 hours of fighting with the push rod and gasket we managed to install the brand new manual fuel pump! after we changed the fuel pump we bled the air out using the turning over method you guys suggested (thank you again btw) it fired right up!! and boy does that baby purr!!! i aired up the tires, threw it in 4L and backed right out of the icy snow bank that was surrounding it without even slipping! but it still needs a little bit more work. so i was hoping you all could help me with something again (because that is what you all are good at)... while driving home i noticed my battery gauge going down, and down.... and down. i drove half way from CT to Cape Cod without headlights in the dark! i even passed a state trooper after i had turned my headlight switch off to conserve battery power and he didnt even pull out of his speed trap:. i tightened the alternator as far as it would go and the belt still wiggles a bit. i know both batteries are junk and i should probably get new ones but i'm thinking of first trying a new alternator belt and new battery clamps first. i'm going to take the alternator off tomorrow morning and get it tested at auto zone. but here's the weird thing... if i parked at a rest stop, left it idling, and turned my headlights off my battery gauge would start going up like it was charging, but then it would go down again once i started driving. What could be the problem? oh and one more thing... my brother lives in Bethel CT, which is on the border to NY and i live in Harwich MA a little over 200 miles away, and when i pulled into my driveway i had 3/4 of a tank left!!!! and i never turned it off (because my batteries were dead and there was no way i was going to get it started again without a jump) except to get gas before i left CT and i stopped at McDonald's. i'm so happy i finally got a diesel! my 8 cylinder K5 gets better gas mileage than my 4 cylinder Camry! hahaha though my Camry does have 300657 miles on it haha!!
