If this is posted already i apologize but i couldn't find it on here and have searched it but came with nothing that i found relevant. I have been having major issues with my 2000 f150 from a buzzing crackling under the dash on the left side, to having to jump my truck every time i turn it off and even had to put my truck in neutral or park to change speeds of my windshield wipers. also had issues with dash lights and the radio flashing with the key out of the ignition, also there is a popping from the relays in the fuse box on the inside and even popping from the one under the hood. also my abs sounds like it is constantly running or pumping although it is unhooked and don't work. now does this sound like the GEM Mod. or am i royally screwed on my limited budget. also the day that i took the GEM out it would not start at all even while being jumped.any help would be amazing. thanks guys
