PLEASE HELP Can anyone tell me the symtoms of a dead ambient air temperature sensor has on a ram 1500 95 5.9L. OR What would cause starting problems as in sometimes it will start. sometimes it kills my battery but will start with boost, and sometimes it won't start, even with a boost. All within a 8-9 day period. But when it does start, or I force it to start with boosting it will run fine . Trip all over town with no decernable hesitations. If a fuel pump is shoot. Can it still operate intermitantly?
