1999 Dodge Ram Repair Question
Dodge Ram Engine Problem
If you have too much fuel, what led you to the pump? It's obviously working. Have you checked for spark? How about diagnostic fault codes? You might look at the map sensor as he has the biggest say in how much fuel goes into the engine. Check for vacuum leaks too since the map sensor measures engine vacuum to determine how much fuel is needed. Map sensor don't fail nearly as often as they did in the late '80s but when they do, they typically were good one minute and bad the next. They don't normally go bad gradually.
To check the codes, cycle the ignition switch from "off" to "run" three times within five seconds without cranking the engine, then after a few seconds the codes will read in the odometer display.
