SOURCE: Replace heater core in 1988 Ford Ranger

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

SOURCE: no fuel pressure on 2.9 litre ford ranger

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.

SOURCE: 1988 ford truck f-150 xlt lariat cant get current to fuel pump

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 :)

A guy just told me that there is a internal fuel pump and a external fuel pump on my 1988 ford ranger xlt 2.9 4x4. is this true?


In some applications, yes there is two.


On the 2.3L and the 2.9L engines to model year 1988 the electric fuel pump system used on these EFI engines consisted of two fuel pumps: a low pressure boost pump mounted in the fuel tank, and a high pressure fuel pump mounted on the frame rail.
The low pressure electric fuel pump is located in the fuel tank and is a part of the fuel gauge sending unit.

1988 ford ranger fuel pumps both come on for 2 seconds and go off.\r\nevery time i turn the key this happens. can i wire the pumps to a hot wire whenever the key is on they will run?


the pumps should run for a couple of seconds then shut off when the regulator determines the fuel pressure is correct. If you wire it, it will probably shorten the life of the regulator since pressure will constantly be applied to the regulator.

What fires injectors 1988 ford ranger have fuel pressure and volume but will not run will run as long as i add fuel through air intake


Remove and test ignition module bolted to the side of distributor. If that is okay then it is more than likely the pick-up coil. Both can be tested for free at any major parts house

1988 ranger 2.9 no fuel pressure new pump


check the pulse on the injector wire with a noid lite or a meter. If no flash then you most likely need a computer. Its called a quad driver in the PCM thats fried. You may have a shorted component that caused it to fail.

Since you say it will run if you add fuel manually I don't suspect the crank sensor because you have spark.
