You have fuel pressure. You need to check the fuel by taking a fuel sample to see if there is water in the fuel or other contaminates. Make sure the spark plugs are getting spark from both coil packs. If you are not getting spark then will need to scan the computer to check for codes in the computer and diagnosis of the codes. The ECM may be defective is not giving spark signal to coils. The vehicle may need to be put on a scanner to monitor data to see if all the signal inputs and outputs are working. I would try to disconnect the mass air flow sensor to see if it starts. It could be the mass air sensor. If you are finding this is the problem, a certified technician can come to your home or office to inspect your vehicle as well as replace the mass airflow sensor.
