2007 5.4l f150 crank but no start,
Hey all, hoping to get pointed in the right direction, I replaced the fuel injectors and intake manifold gasket in my truck and now my truck cranks but will not fire, it started 2 times and idled very rough and died while giving it a little throttle, I already replaced the fuel driver model and all coil packs and spark plugs are new, when starting the truck the first time I forgot to let the fuel system pressurize before cranking, not sure of that would have caused an issue, I've been playing with things for over a week now, I have spark on all coils and plugs, injectors appear to have power, I can smell gas during cranking. I'e disconnected battery to drain power out to computer to reset, ive trying using a little bit of starting fluid, I also replaced brake booster vac line behind intake manifold

Dead battery
I have a 04 Lariat 4x4 (new body style). Nothing aftermarket except for Edge Evo programmer. I have spoke with several "experts" on my issues, but nobody can give me a correct answer.
Truck will randomly die (battery) within a 5-8 hour period. Mostly overnight. When I say dead, I mean so dead that the door wont even unlock with the key fob. The battery is brand new and checked out good. Even more strange is that once the battery is charged, it may start perfectly fine for months. Or it may be completely drained again within 5-8 hours. No fuses are blown, and when charged everything works perfectly fine. I have no idea what the problem is or could be. Apparently, no one else does either. I am almost to the point of selling this truck due to this issue. I love the truck when it is working correctly, but an undependable vehicle is useless. Please someone help me. This is driving me crazy

When I first bought my 04 Lariat from a good friend, all sorts of weird things started to happen. Turns out, up middle back up light had a bad seal and water leaked down by the microprocessor. Hmmm. New light seal and dried out the processor and all works well for ten years plus.

No crank no start
I have a 2005 F-150 with the 5.4 triton. Over the past 3 years I have had everything looked at on it and it will not start. When you turn the key the lights , windows and radio all work. When It started having problems it would start when it wanted. Sometimes I would jiggle the keys around and it would start. I have said from the beginning that I thought it need a new chip key made. I called a locksmith today and he wanted to argue with me telling me chip keys don't go bad. One shop changed the ignition and put the old one back in.because it still didn't start. I'm thinking key or ignition switch maybe. Any suggestions

Describe what happens when you turn the key On. Then when you turn it to Start. The theft light should go out, then the engine should crank when you turn it to Start.

Theft indicator The theft indicator is located on top of the instrument panel. • When the ignition is in the 1 (OFF/LOCK) position, the indicator will flash once every 2 seconds to indicate the SecuriLock system is functioning as a theft deterrent. • When the ignition is in the 3 (ON) position, the indicator will glow for 3 seconds to indicate normal system functionality. If a problem occurs with the SecuriLock system, the indicator will flash rapidly or glow steadily when the ignition is in the 3 (ON) position. If this occurs, the vehicle should be taken to an authorized dealer for service. Automatic armi
