Thank you for the answer, actually when I turn ignition ON, I can hear the fuel pump turning, a friend of mine advised me to put some injectors cleanser liquid in the fuel tank and force the ignition because it did not really run for two years so still same fuel.
Also, when I try to start the engine several times, I can smell fuel vapors at a time.
What about if I change the fuel pump relay, where is its location?
Thanks a lot again.

If you can hear the pump the relay is fine, i would drain the tank, lines and replace filter, add a little metho to the tank and fill with fresh fuel see how that helps.

Ok then, I will try this, could it be the inertia switch or cut off, something like this that I have to reset, I've heard about this also, I will let you know what happens.
Thank you for the help!

P0503 = Vehicle Speed Sensor "A" Intermittent/Erratic/High
P0628 Fuel Pump Relay Control Circuit Low Voltage

I would be checking the fuel pump first. see if you have pressuer in the system with the ignition turned on.
