Don't know what to check next. Plugs are fine. Turns over, fuel pressure is 55 psi, changed the fuel filter anyway...what is our next step?
When you say it fires, are you checking for spark at the plugs ?
In most cases you have to figure out if it is spark, fuel, or compression to proceed. A mechanic would also check the computer for trouble codes but you would need a scanner or code reader to do that.

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

if it does not start after you check your distributor cap that means you took the car out of timing, when you put the distributor cap back on you did not put it is the correct position, now you need a mechanic to get the timing of the engine

Could be as simple as your fuel filter...after the truck starts..can you keep it runing by gunning the motor?
If you can feather the accelerator to keep the motor runing, I'd start at the filter, and then check the fuel pump

Do you have any engines codes like P 0300. Sounds like ignition coils ,check input wires to coils if okay replace both coils.I have seen this few times

Plug wires breaking down change and try.allso the plugs can breakdown under pressure change them while your at it.

We got it to start for a second using starter fluid in the carburator, then it died, otherwise, we do have spark, it tries to start. Tomorrow we are changing the fuel filter just in case but after that, we are kind of lost as to what to check next.
If it will run on starting fluid, and you know for a fact the fuel line has 55 psi of pressure, I would say something is not allowing the injectors to open.
