Dirtymilkman Posted November 30, 2018 Share Posted November 30, 2018 Check box on driver side firewall under the hood for corrosion. The steer tire likes to throw a lot of crap into it.

Moparmike Posted November 30, 2018 Author Share Posted November 30, 2018 Can someone tell me where all the truck grounds are on a 2000 rd I'd like to check those as well Quote Link to comment https://www.bigmacktrucks.com/topic/54918-2000-ed-e7-just-stopped-pulling/#findComment-410386 Share on other sites More sharing options...
fjh Posted November 30, 2018 Share Posted November 30, 2018 Check the grounds down under the starter big bolt 15 / 16 head also if its an RD check the vehicle ECU plug under the dash rh side for being greened out as it faces up and if the windshields leak it can cause similar issues!

It will outline a complete ground cleaning and check.
