HELP IT WILL NOT START
2000 ford Excursion 6.8 v10 209K miles
So to make a long story short I went out to start it one day and it wouldn't start. I tested everything and it's not getting fuel for some reason so I did the normal investigation started from the fuel pump and Basically replaced the entire fuel system. fuel pump, fuel filter, fuel pressure regulator, fuel pump relay, and fuel pump fuse all replaced. I checked the inertia switch as well. Basically I figured out that the PCM is not sending signal to the relay. Once I jumped the relay the pump came on so I tried to start it with the relay jumped for diagnostic purposes. It still would not start. I then tested the injectors and none of them are firing so do you think the PCM is bad or is there something else I need to check because there is nothing else I can think of.

Could be the PCM diode (if you have one) take a look at my reply on this thread https://www.ford-trucks.com/forums/1...k-no-fuel.html
