2002 Ford Mustang

Car is a gt and I stalled on me one day, it started right back no problem. The next day when I started it the guages did a full sweep whuch was unusual so I started checking everything and the negative battery cable was loose. This fixed the sweeping guage. But the car is now sometimes hard to start. It will crank and take about 15 seconds to catch and slowly build the rpms up. It does not always do this. If you turn the key on and let it set for about 5 seconds it will crank up normally. It idles at about 500 in gear and 650 to 700 in park. I have replace the crank sensor, tps sensor, cleaned the iac, cleaned the mass air sensor, replaced fuel filter. The mass air and iac each test to be good performing test with the volt meter. I have also checked the fuel pressure and it seems to be in spec. It goes up to 40 when key is on, is at 30 when idling and when you unhook the regulator it goes up to 40 and all this is what the book sayes it should.

Ok, what was the fuel pressure when it stalled and would not start?

My wife was driving it when it stall. At home when I have been working on it it maintains a steady 30 psi on my guage which by the repair manual is correct. It will jump up to about 40 when you hit the gas hard but then remains at 30 psi. I think I have narrowed it down to the mass air sensor as I have unplugged it and even though it takes a little longer to start I no longer have the long cranking symptom. My daughter is the main driver of he car and she also informed me that the fuel mileage has gone down drasticly in the last few weeks.
