Fuse box diagrams are on pages 170-172. I hope this helps, you can save and print this manual so that you have a copy of an owners manual for your vehicle.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?

You dont need another fuel tank. Running a vehicle out of gas allows any trash or goo to get in the fuel system. Trash mostly is trapped at the pump inlet screen and in the filter. GOO can make its way into the injectors. Throw in a bottle of injector cleaner. A sure indication of a bad fuel pump is an audible constant change in rpm's. It sounds like it's changing gears.

tho only difference would be the electrical connections for the radiator fan (your 70's truck had a belt), it is pretty much the same thing and probably somewhat easier. Drain it first, then you'll need to remove the trans lines, hoses, the top support, bolts that hold the radiator to the frame and the attachments of the fan to the radiator-it shouldn't be a hard job, the

the mass air flow sensor is inside the plastic housing that the air filter ins installed in. The housing separates with a metal band and the rear half contains the sensor. there should be 3 or 4 tabs that have to be depressed with a screwdriver to open the rear half of the housing.

yes that is called blow bye you need to change the pcv valve and make shore the hose is clean inside and that will take care of it .take care mart

The factory code is usually listed in the owner's manual.
If someone changed the code, then you will have to take it to a dealership to have the code reset.

Are you check fuses and voltage? Also I suggest check ground.

check fuse but after that the master switch on the drivers door needs tested and replaced

In the fuse box located on the drivers side of the dashboard, you want to check fuse 18 - it is a 25 amp fuse for running the power seats and also the auto-lock relays if I remember correctly.

YOU CAN REPLACE THE TIMING CHAIN AND GEARS, OR CHANGE ENGINES! CHECK THE PRICE OF THE TIMING CHAIN AND GEARS, AND GASKETS! THEN COMPARE TO COST TO CHANGING THE ENGINE!

If you have Coil -On Plug system,you remove the
coils,the plugs are under them

Don't put any pipe dope on them as it may return to the Auto transmission and foul the valve body. The lines may be rusty under the fittings and have corroded to the point of leaking. For the price of a Rebuilt transmission it is probably better to replace the 2 lines.

There is usually no warning that the fluid is low in the transmission. With a 12 Year old vehicle, rust is always a possibility. I would say you can try to snug up the fittings at the Radiator, but so much is plastic or soft metal that the new lines are probably cheaper than a Radiator too.

I am about ready to do the same job on my 1999 F150. While you are under the Mountaineer check out your Brakelines. I had 1 let go and the rest were scary bad. I painted the Autotrans lines to get through Winter, as well as the oilpan. Also check out your Power steering Reservoir line that goes under the ABS unit. The metal part of that line likes to rust at the plastic body clip.

Go to salvage yard and get the proper one and put back in or go to parts store or dealer and get a new one, check around the new heater control valve and see if there is any wires or lines to go to the original one, compare to one complete in salvage yard or a car lot to see what you'll all need to get it done right.
