I ALREAADY DONATED ON SAME QUESTION ON SUNDAY
1997 Ford F150 V8 Four Wheel Drive Automatic
my 1997 f150 4.6L v8 4wd was running great. I drove it about 40 miles running errands stopping twice, once to put gas in it. I returned home and parked it for about an hour and then restarted it to move it around the house to unload. I then restarted it and parked it in the driveway. The following day I jumped in to take another trip and it would not start. It would turn over but would not hit. I did some crude investigating (depressed the relief valve on the fuel rail) and decided that the fuel pump needed to be replaced. picked one up at the junk yard and swapped it out and no results. I borrowed a fuel pressure gage and it registers 40psi. I have since removed a spark plug wire and it seems that there is no fire. (used a screwdriver to try to get spark to ground). I am getting really frustrated with the complexity of this vehicle and need to know where to go from here. Any assistance would be appreciated.
Thanks

P.S. I also looked into the oil fill cap on the valve cover just to make sure that the timing chain/belt (i dont know which it has since it appears to have dual overhead cams) was not broken. when cranking the engine i can see movement within the valve cover. like I said it appears to have dual overhead cams since what I am seeing seems to be the end of a camshaft rotating
