2001 7.3 Excursion Will Crank But Won't Start
Hi, I have an '01 7.3 Excursion and am having troubles with it starting. I live in Steamboat Springs and it has been extremely cold (below 0) for the past few weeks. For the past month or so my X would start fine in very cold weather, even when it wasn't plugged in. Now, all of a sudden it won't start. I had my batteries checked and they were both no good, so I replaced those. It cranks really well, but doesn't start and really doesn't even seem to try. I plugged in the block heater and it doesn't seem to be working. I know that about a week ago, the block heater was working, because I had it plugged in and the engine was warm to the touch. I know it is getting fuel because I started it with ether and it kept running fine. I shut the truck off and started it again while still hot, no problem.
Does anybody have suggestions on what to check to find out what's keeping it from starting? Any fuses or simple fixes that could both cause the X to not start or keep the block heater from working?
