I've checked to see if i had gas an yes the fuel pump is working and i checked for spark and yes i have spark. when i lost power if felt just like i had ran out of gas but had a full take thats why i checked fuel pump and gas filter to make sure i was getting gas, then i checked to make sure i was getting spark which i am, car turns over fine when you try to start it but will not fire
I don't know liter size of engine? Use a gage and check proper fuel pressure, my info says 38--45 psi. If you take any fuel lines loose, make sure no pressure, first.
Did you check fuel injector pulse? The 1.8L and 1.9L engine show close to same fuel pressure. Fuel--spark--compression proper amount and proper time.
Clogged air filter ? Needs air into the engine also ,plus compression . Are the fuel injectors spraying fuel into the engine ? Try spraying starting fluid into the engine through the throttle plate and seeing if it starts then ? If it does ,fuel injector problems .

So you have power there, why not try a little whap with rubber hammer near it while key on to see if it will do anything. I;d try it just to see if it will come back to life.

The timing belt should not have been affwcted. Sounds like you have everything chk'd and accounted for.. The best way to chk the cam and crank is a compression test.

HAVE YOU TRIED CHECKING THE FUEL PUMP RELAY

It sounds to me like you replaced everything but the most likely cause of a stall while driving...The crank sensor.
