When charge the battery fully it cranks engine strong but doesnt fire up

Hello. I would recommend checking a Chilton book to determine where the timing marks for the crank pulley are located. Chilton books provide an abundance of information that will help in diagnosing and repairing your vehicle. As for the fuel pressure, this test is best performed with a fuel pressure tester for accurate results. I would recommend checking the fuel pressure again with a gauge to determine if it is within factory specification. If the fuel pressure is low, it is likely that you have a fuel delivery issue. If this is the case, replacing the fuel filter or fuel pump will likely resolve the issue. If you are in doubt about this repair, I would recommend enlisting the assistance of a professional from YourMechanic who can inspect your no-start condition and replace the fuel pump or fuel filter if necessary.
