You checked the plugs. Did you check for spark?
The coils on this motor could in theory fire the spark if the plug was two blocks away. So good plugs a bonus but you need to know if you have good spark. Take one coil out. Get a spare sparkplug(DONT USE THE ONE OUT OF THE CYLINDER FROM THE COIL) the reason is if the fuel sprays out on the sparkplug and it ignites. Car goes up in flames(personal experience) ground the plug usually a wire or something touch the threads of the plug to metal, have a friend crank the car and watch and listen for spark. Should see bright blue spark and hear the snap

If you have good spark. And are getting good fuel pressure. The only thing left is compression. Take all the plugs out and run a compression test. Wright down your findings on paper and mark which cylinders. For future reference.

Would the fuel pump be bad if it started and ran for 10 secs then died, now it will not start back. You can't even hear the fuel pump kick on and there is no pressure in the line. Would it possible be the fuel pump being loose or just went bad? It's cranking, but will not start up.

The fuse was checked, it's fine, the relay was reset, nothing.

Was driving down highway and it just shut off. I got it back to my place. It cranks over but will not start. Used starting fluid still would not start. Where should I start to look to fix problem?

Car has been sitting in a barn for 5yrs, put new fuel filter and battery in, it starts for 10-15 seconds then shuts off, and wont restart for a few days, it was almost out of gas I put 2new gallons of premium in, anyone have any help or places I could look? Dont really have the money to bring it in so any help would be much appreciated thanks, also how do I bleed the system? Also not sure if I posted in the right category lol

I have a 2001 Lincoln LS 3.9 V8. It will turn over but will not start. The battery is brand new and so is the fuel filter. I can hear the fuel pump wind when the key is on. Ive gotten it to start twice but the engine knocks so I shut the car off. Ive had it since 84,000 miles (now has 130,000) and perform routine maintenance. I've had no problems accept I replaced two coil packs a while back. I ran OBDII but it wont give me numerical codes, it says OH C E EV something along those lines. I am stumpedany help is appreciated and I wont leave you hanging!
