Truck turns over but wont' start. I think it's the PCM Relay (#2), but not sure
I have a 2003 F150 5.4L. About once every couple weeks, and I don't know why, my truck won't start. It turns over and is trying, but it won't fire up. If I go back a few hours later, sometimes it starts. Also, if I jump start it, it usually starts (sometimes it doesn't though)
I pulled off the fuse cover and noticed that relay #2 (the one for the PCM) was really hot. I could touch it, but it is very hot. It is also yellow and all the other relays are black. That makes me think it has been replaced before. Does that usually get hot when starting the truck?
Do those symptoms match what would happen if that relay was bad?
Thanks for your help!
