98 ford explorer fuel pump pressure

The relay is under the hood in the power dist. box, the cut off switch is located in the side panel in the rear cargo area

Have a shop check fuel trim & determine if you
have fuel injectors that leak & need to be removed,
mailed away & cleaned & tested

check the yel/blk yel/red yel/wht wires from control mod to the coil

Just becouse you ear the fuel pump runing when you crank the engine,does`n mean that has the right pressure,make sure you have the right pressure.

Check the fuel pump relay connections, the Explorer is bad about connection corrosion at the relays, try unplugging it and sticking it back in. Hope this help, let me know.

take it to a mechinc shop and have them do a pressure test

I would next check the fuel pressure regulator if the pump was not pumping, or the filter was plugged some of the leftover waste in the lines from one or the other of these issues may have plugged the regulator causing inconsistent fuel pressure that would cause the engine to run rough, or possibley cut out fuel entirely, causing the vehicle to die

22 is a map/baro sensor code. They have a high failure rate often seen by GOOP or silicon in the vacuum hose near the sensor (it leaked out of the sensor when the sensor innards failed). 98 is a fuel pump circuit code. I would tend to think your main problem is the map, they can get very iffy and intermittant when they go bad. as usual, have an expert diagnose both codes properly.

Your fuel filter is probably clogged

You most likely have a faulty fuel pump. You could try replacing the fuel filter first just in case it's a clogged filter. If that doesn't work replace the pump.
