How do you know it is the fuel pump system? Did you have it diaged or is it a guess

Have a helper get underneath and listen to the fuel pump while you turn key on-is it humming? If so -check the fuel pressure and injector pulses

I have checked the fuel pump and it has the proper amount of pressure. Could it be the main relay or something electrical

Are the injectors opening and closing? If so -look for ignition spark

Check for compression first. You need to start at basics. Then go to speark, check for spark at the plugs.

You said the fuel pressure is good-again are the injectors pulsing meaning being snchronized by the computer providing fuel into the cylinders

We had pressure in the fuel pump yesterday and now it isn't registering anything.
