Default 2004 altima with starting issues

Can anyone PLEASE help me? I have a 2004 altima 2.5s, 4 cylinder. I have to start it with my foot on the gas or it will not start at all. If i drive down the block to the store and run in the store for a few minutes and come back out the car will not start at all at least for an hour. I have already replaced the cam and crank sensors under the recall as well as just recently replaced because the computer was giving a code of p0340. I aslo had the ecm reprogramed under the recall and then that also was replaced with a new one. I had the cat replaced and a complete tune up (new spark plugs,filters). Now with the lastest repair of the new sensors the fuel injectors are only getting intermittent pulse/spark. I am at a loss for what to do. There are no codes stored in the computer. Can anyone please help. Thank you.

The first thing I suggest doing is checking for fuel pressure. You need to connect a fuel pressure gauge to the fuel line before the injector rail. The fuel pressure should be around 50 psi at idle, and it should remain at around 50 for at least 1 hr after you turn off the engine. If the pressure goes down the there is a fuel leak or the fuel pump needs to be replaced.
