So I know there is an extreme draw from somewhere but I don't know how to test for it when the volts are dropping that quickly. The previous owner has messed with some wiring and it's referbed 7.3 idi in a 89 f350. I'm not sure how to test for a draw when i only have 10 minutes until the battery dies! any ideas of what i could do to find the issue, before i just start cutting non essentials! Any advice would be amazing! Thank you

while going down the road my truck will stutter orhesitate i can switch from tank 1 to2 and it will catch again. especially goin up hill. it acts like it is running out of gas

It's a beautiful truck only used for towing horses in a trailer

auto transmission seems to slip from overdrive to drive causing rpm's to get to high and slips in just drive more often the meter reading on the selenoids was the same in the first 2 [about20.2 approx. on all]it has new filter and fluid and did not smell burnt and also not to much shavings or trash in filter not at magnet in pan

i have two tanks and two low pressure fuel pumps and a high pressure fuel pump and none of them are working change the relay and fuel filter still no gas i can,t see all three pumps burning out at the same time in both tanks also checked fuse under dash is there another fuse some where else

7,3 diesel

When I start it it knocks when I drive it knocks. Thinking a sloppy wrist pin or something along them lines any ideas??????

Meaning the back drums and front calibers, I also have replaced the booster, master cylinder, & the ABS block on the frame for the back brakes only. I used the Haynes auto manual & procedures to bleed the system properly as well as installation. I have got a good petal to start with but it will leak down if I hold it down for a short period of time so I'm totally confused on what is going on here any suggestions will be greatly appreciate.
