Question Asked: truck dies at start up
January 03, 2010, 08:57 AM
My truck dies immediately when i try to start it and won't idle. I took the charging relay out and the truck starts and idles normally but the battery will not charge. When I replaced a new relay the truck dies at start up. I had the alternator checked ( it was bad) so I replaced the alternator by a shop and the problem still exists. I don't know if there is an in line fuse or not. If it is an in line fuse, could it cause this problem? The shop told me that it could be the ECM. Of course I'm not so sure that their diagnosis is correct. If it is the ECM, will it tell me what's wrong with a full diagnostic? Is it the relay, or something else? I don't understand why the truck will run without the charging relay. Could it be the fuel pump relay.? Has anyone else had this same problem? If so, please help.
