06 5.4 Cranks but wont start
Truck has been running perfect and is my daily driver. Went grocery shopping with the wife and made two stops and drove it home. Parked in the driveway. No hint of any issues but when I went out a couple of hours later we went to head out to dinner and it cranks and doesnt start. Nothing out of the ordinary anywhere. No check engines lights, no theft lights flashing, nothing to indicate an issue. Engine sounds perfectly normal cranking, I can hear the fuel pump when I turn the key. I cleaned the battery terminals today because they had some corrosion and I checked all of the fuses that have anything to do with fuel or fire and nothing was blown. I also went and bought a Fuel Pump Drive Module and installed it and still nothing so I took it back. $113 for that thing so I wasnt keeping it. This is a pretty pampered truck, not a torn up beater. Any ideas what else I should check? Will probably town it to a shop tomorrow if I dont have anything else to try but I am at a loss at this point. I tried to listen with a stethoscope and I dont hear the injectors firing or the COP's. Oh I also shot it with starting fluid and nothing happened so I dont believe its fuel related. I think something is keeping it from firing the COP's or the injectors arent firing. But what could it be? nothing happend to the truck last time I drove it. Oh I did check the fuel pump cutoff button as well. Nothing there either.
Update, Per a request from someone else I went out to check the anti theft light and when I locked the truck with my remote and armed the alarm it started going off a few seconds later as if I tripped the alarm. Not sure why it did that, It normally arms fine

Went out last night to tow it to a shop and it acted like the battery was totally drained. No lights no nothing, just the little red blinking light on the top of the dash was still slowly flashing. Put the charger on it and the headlights came on as though the battery had been connected but the charger was only at about 1 amp as though the battery had juice and then it clicked and went to 0 and the truck was dead again, then it clicked and went back into charging mode. Did this a few times so I took the charger off of it and checked and the battery showed 12 volts on the posts. took the positive terminal off and still 12. Put it back on and then the truck had juice again. Very strange. Did not have enough to crank, just click the solenoid but very odd. The terminals are clean, I had just cleaned when the problems all started just to be safe. Very odd. Could a bad battery still allow the truck to crank just fine but not fire up?
