allow the system to cool down
take radiator cap loose to release pressure
once pressure is released tighten cap
loosen clamps on the heater hoses in the engine compartment on the pass. side of firewall.
plug or cap off the heater core tubes to prevent spillage when you pull it into the truck
place a trash bag on floorboard in case spillage occurs
remove the five screws holding the heatre core access cover, three on top and two on bottom
carefully pull heater core back and down and remove it from the dash
install is reverse
Hope this helps

is the pumps running have you checked fuel comes out of it? if it does you will have to move on further along fuel line check next connection (fuel filter maybe) check there is stuff coming through there. Next goto other side of filter check there. Just go along the fuel line checking for fuel pressure. if there is fuel going all the way to the rail check the pressure regulator it may be stuck open therefore the gas would be getting pumped to the rail and going straight back to the tank i.e. no pressure.

Have you checked the 'inertia switch' which in the event of an accident shuts off the fuel supply to prevent a fire . It's usually located in the cab on pass. side. Some models have one reset button, some 2 which have to be pressed at the same time. If that's not it, here's how the power to the pump SHOULD work, you will have to follow the path to see where it stops. When you turn the key on it turns on the EEC power relay on, this relay then provides power to the PCM (power control module) and the control side of the fuel pump relay. Power for the fuel pump is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse current flows thru the fuel pump relay and inertia switch to the fuel pump. The fuel pump relay is controlled by the PCM. When the ignition switch is turned on the fuel pump will operate, if the switch is NOT turned to start position, the PCM will shut off the fuel pump off after 1 second. This is to avoid flooding the engine when it is not running, just key on. So check out to see if you have a fuse link or a high current fuse and if they are blown.

Though it's a bit late from when this question was asked... But... I replaced my timing belt before it broke. Like anything else on my 88 ford ranger it was the easiest thing! If your really carefull and remove the plugs! You must remove the plugs because of the compression that's there waiting to fire when you next start the car. Dissasemble the fan, fan cover, and the pulley and the plastic cover. Not exactly in that order, just what you need to access the belt. Score or mark or paint where one or two teeth of each pulley is in reference to a non moving part of the truck (you can rotate the whole thing to a convient setup by hand) make sure when you rotate the assembly it feels somewhat free you can see and feel that there is no tension on the belt in ANY area. When you have all the marks set up loosen the bolt holding the tensioner use a bar to move the tensioner out of the way just enough then tighten the bolt on the tensioner, that will keep it locked open while you simply and carefully slide out the belt then slide in the new belt keeping the marks 'still', just go slow and keep your eyes open. Maybe I just got lucky...But the theory is sound and worked for me.
Probably could use a diming light to make sure but I don't have one and the truck still runs fine. Oh and by the way... if you ever need to replace the heater core it'll take you all of 20 mins if you have even the basic of abilities and the right screw driver :)
