MY ARMADA CUTS OUT AT 60MPH IS IT FUEL FILTER

I looked fuel filter for your vehicle in my database. 5.6L engine, fuel filter is park of fuel pump assembly. With your model year, I replace whole assembly. I don't know if you can replace filter separately?

Fuel injectors need cleaning or fuel filter needs to be replaced. The most obvious things.

upon researching this make & model of car it seem that the fuel filter is located in the fuel tank on the fuel pump & should not need replacing unless your tank is dirty.

Check your in line fuel filter.

I would consider testing the fuel pump pressure, check all fuel lines under car and unplug the fuel pressure regulator once to see if there is a change when you start it. If there is a check engine light after doing that simply remove your neg battery terminal for a few (IF YOU HAVE THE ANTI-THEFT STEREO IN YOUR CAR MAKE SURE YOU HAVE THE RESET CODE FOR YOUR RADIO)

I had this before but you said you already changed the fuel filter. It was giving me a code that pointed to the injectors because they were starving for fuel. After changing the filter it worked. Your problem must be in fuel delivery somewhere.

flashing normally means some kind of severe missfire you need to get the code pulled to know what direction to go in you can also try checking fuel pressure

Change fuel filter.

could be fuel delivery problem. change fuel filter, flush fuel lines.

check the fuel filter, fuel pump, fuel pump relay, also check the main relay located behind the centre console, behind the radio

A RESTRICTED FUEL FILTER WILL PROHIBIT PROPER FUEL DELIVERY....CHECK THE FUEL FILTER OR POSSIBLE A WEAK FUEL PUMP...THE ENGINE MAY BE STARVING FOR FUEL AT HIGHER FUEL DEMANDS
