I just bought a 2002 f350 with 285k on it. When the engine is cold it has a hard time starting then it has to warm up for 20 minutes before it will drive. (if you try and drive it it has no power) The previous owner told me it has new glow plugs and injectors within the last 1k miles. It starts as if the glow plugs arent cycling properly. Its a california emmisions truck so it has the glow plug module. (no codes) I'm wondering if there is a good way to test the module? if i understand it properly the module replaces the relay? any help would be great.
