Security. Light flasing?

First post, welcome to site. How many miles on truck, any background history of problems?

Same here good fuel pressure no spark no firing of injectors

Thanks for the welcome
But is there anyone with any information?

You need to check fuel pressure. The pump will always do the 3 second prime but can loose communication with the pcm. I'd look at either the fpdm or a broken wire

I have a 2012 but still a 3rd generation and had this same problem. Nobody could figure it out. I was having to use both starter relays to start it. Put one in, go turn the key on, then go put the second one in and it would start right up but one day a friend was looking and found the problem accidentally. Under the dash, straight down from steering column, there is a plastic piece that reminds me of one that plugs in a treadmill. Apparently I had bumped it with my knee and it was loose. He unplugged it and plugged it back in and it fired right up and has never given me any problems again. I couldn't find it in the manual but I think it could have something to do with the auto theft system. Sorry for the length of post but may help you out. I hope so.

Does it try to start? Like for about 2 seconds? If so I'd check air intake all the way to the throttle body. An air leak can ruin your whole day! Found mine where the hose (70mm) connected to the throttle body. Mechanic didn't get the hose on properly and vibration opened it right up! Good Luck!

Asked if there is any history of problems, lot of issue's reoccur. Sounds like you are changing parts and not diagnosing the problem. What put you down the path of electrical?
