Electrical Nightmare

[stamp11127]

Too high of a current load through the wire and fuse.

I noticed odometer reading comes and goes. It always reads in start position but mostly dashes in run. This is a sign of no communication correct? My brother is out of town with my Solaris pro so I cannot test data port

Trevor, your one of the most electrical knowledgeable new members we've had in a long time. After you/we figure out your problem, you will be a great asset to the forum. In particular your electrical knowledge. Are you a electrical engineer by trade?

I was a heavy equipment mechanic for 7 years. The past 2 years I have done low voltage security work like door access systems and alarm for schools. I know my way around a meter fairly well whether under a dashboard or in a ceiling. I appreciate all you guys are doing for me and I hope a can return the favor for someone else here. I am a member of several Chevrolet forums but this is my first Ford. Seems to be a good group of people, without many trolls!

Well guys I’ve done more testing. With light I have no pulse on either injector or coil, although I do have power to them with key. I was never able to find the pcm pinout, but I did unplug it and probe and mark all powers and grounds key on and key off. Also checked power drop on these with it plugged in and found 2.2v, which seems acceptable although slightly high based on my experience. Apparently my fpdm is in the tank as I cannot find it. I am having a serious power draw with key off, possibly unrelated to issue as it has aftermarket competition stereo and multiple TVs. Sounding like pcm? I wish I could find the diagram so I could insure the pcm is powering on
