Hard starting due to low fuel pressure on Suzuki Forenza

Problem Description and Possible Solution

A hard starting condition may be due to low fuel pressure. Our technicians tell us the powertrain control module (PCM) should energize the fuel pump for 2 seconds when the ignition is turned on in order to properly pressurize the fuel system. Correcting this condition may require updating the PCM software.

hard to start in the morning after that it runs and starts every time. Just in the morning or after it has been sitting for a few hours like 6hrs or so it is hard to start. haven`t fixed the problem yet was going to check fuel filter but now I will check the pcm etc.
Takes at least 2 tries before it will finally crank. Often it can take up to 5 or 6 times before the engine fires up.
It is very difficult to make it start in the morning. Changed battery, spark plugs, but so far not solved the problem!

Any ideas?
Hard start in the mornings. After that, runs fine thru out the day. Need help to solve this problem.
