Thanks for responding, I was thinking no one would. After my posting, my initial experiment could not be repeated. That ruled out the FICM as the problem.
I went to my local Ford agency, and they said it was probably a high-pressure fuel leak, and wanted $1500 to diagnose it..
I have the truck apart now. My research convinced me to check the HPOP connection. I took it apart & sure enough, the fitting was blown out. Interestingly, the Ford kit is $65, and the International kit is $29 & has about twice as much stuff in it.
During the process, I dropped a bolt down the back of the motor
Pulled the pan, not there. Had to pull the trans & remove the plate on the back of the block to access the timing gear cavity. It was wedged behind the cam gear. I put the trans back in today & as of right now (9:30 pm) I think about 4 or 5 more hours will do it.
p.s. when you work on the HPOP please be smarter than me & stuff rags around the opening so you do not get to spend couple of days getting bits out.
