It could be: clogged fuel filter, bad fuel pump, or the cutoff switch. Could be fuel pump relay. It's in the engine compartment fues block, and labeled "Fuel Pump"
If it's either the filter or the pump, replace both at the same time, it's cheaper.
The fuel cutoff in located in the trunk, along the driver side rear fender, you have to pull all the carpeting and such out on that side to get to it. It's marked "Fuel cutoff" Not sure on the 626, you might just have to push the reset button on the module.
However I doubt this is your problem I would think it's either the relay, the filter or pump.

This is kind of a long shot but if it is difficult to start after sitting all night but then starts just fine during the rest of the day then you may be just a pound or two low on fuel pressure. This engine needs a minimum of 60 psi of fuel to start properly. If you have only 59 psi it will crank and crank and finally start but will behave all day long as if nothing was ever wrong. You could also have a leaky fuel regulator or injector that is causing it to be partially flooded when you attempt to start it but usually those problems bothers more after the engine is warmed up. Even some new fuel pumps won't put out the needed 60+ psi and sometimes the fuel pressure regulator can go bad and not allow the pressure to build up to the 60+ psi range. The only true way to know for certain what the actual pressure is to have someone test it with a very accurate test gauge. Hope this helps out a bit and good luck.

Take the air cleaner off and open the throttle (have someone hold the gas pedal to the floor) and look down into the intake manifold, if you see gasoline, the Fuel Pressure Regulator may be leaking sometimes there are plastic fuel lines inside that can leak also. When either of these leak, the engine should run REAL BAD/RICH. Black smoke coming from tail pipe.

This happens due to a failed or failing antitheft system. When the system cant communicate properly, it will disable your starter or injectors and show the SECURITY light. Go to this link for info and ways to beat this system yourself.
