There appears to be random spark but the car will not start.fuel is present and pressureized on the fuel rail. got any ideas

Did you check for spark at any ot the spark plug wires/ coils? If there is, check for fuel pressure at the fuel rail. Take the port cap off and connect a fuel pressure gauge. If one is not available, with a pocket screw driver deppress valve at port and observe if fuel pours out. If no fuel comes out at all, check your fuel pump circuit. Check for good ground and power at fuel pump connector. If power/ground are ok, replace fuel pump. If spark and good fuel pressure is present, there is the possibility of engine mechanical issues(jumped) timing chain). Also, a plugged catalitic wont let engine start but its very unlikely thats your problem. Start with your basics: spark, fuel, engine mechanical and catalitic.

Are you getting fuel pressure from the pump to the fuel rail? You need to do a fuel pressure test to determine if there is actually a fuel supply to the fuel rail. Is the vehicle getting spark? Have you removed a plug wire and grounded it out while cranking the engine over to test for spark? How did you come to the conclusion the fuel pump was bad? Was the fuel filter changed as well?

code p 0300 refers to random/multiple cylinder misfires detected ===causes spark plugs ---HT leads ---injector/s--ignition coil/s---low compression---wiring
code p 0522 refers to engine oil pressure sensor/switch--low voltage ===causes wiring short to ground ---engine oil pressure sensor /switch---ECM
for the first code having to alter the accelerator position ( which tells the ECM to let in more fuel indicates either a low pressure in the fuel manifold or that the injectors need cleaning
At high way speeds when the engine appears to be running good , it is still possible to have random misfires caused by low fuel pressures and /or dirty injector tips
It would be a good idea to check the oil pressure with a mechanical gauge ,then replace the oil pressure sensor/switch

DO THE SPARKS HAPPEN AT THE RIGHT TIMING OF THE CRANK?
TRY TO START IT WHILE SPRAYING STARTER FUEL INTO THE AIR FILTER. THAT WILL NARROW THE SCOPE.

check your fuel pressure, then check your spark plugs to see weather or not they are wet with fuel, if they are dry remove the fuel rail and check to see if they are spraying fuel, make sure coils are good,

Wheres the spark, you need to test for spark,there is a crank sensor located transmission bell housing

Check spark at spark plug using a spark tester and fuel pressure at the rail when it acts up. If the pressure is ok at the rail, but the injectors aren't firing, that can point to a bad computer.If the fuel pressure is present but the spark is not being supplied to spark plug wires to spark plugs, then an ignition module might be in need of replacement (the metal plate the coil packs sit on). If the engine has a service engine soon light before it dies, maybe check the codes that should be stored in the computer using an OBD-I scanner.

you said fuel rail has pressure , why do you want keep checking fuel system?
check ignition , and if no spark present check reference sensor(crank position sensor) , if it's bad you won't get spark or fuel.

check rings

Remove a spark plug, plug it into the spark plug wire, attach a jumper wire from the hook of spark plug to ground and have an assistant turn over the engine while you check for spark, If spark is present check for the presence of fuel pressure at the fuel rail, there is an access valve, if you can't aquire a pressure tester wear safety glasses unscrew schrader protective cap exposing the access valve on the fuel rail with key on press in on the pin in valve like you would to drain air from a tire, be careful because the line is pressurized and gas should squirt out possibly at your face I prefer using a screw on gauge. If fuel pressure (30-40 psi) is present, then look for bad connections to sensors and fuel injectors pull of the electrical plugs on sensors and injectors and reattach sometimes this does wonders sometimes nothing, but as you know intermittent electrical problems can be the most difficult to solve on these newer engines.
